These external cues can be celestial cues, such as the sun or polarized light, which are processed in a brain region termed the central complex (CX). Previous research typically focused on how individual simulated celestial cues are encoded in the butterfly's CX. However, in nature, the butterflies perceive several celestial cues at the same time and need to integrate them to effectively use the compound of all cues for orientation. In addition, a recent behavioral study revealed that monarch butterflies can rely on terrestrial cues, such as the panoramic skyline, for orientation and use them in combination with the sun to maintain a directed flight course. How the CX encodes a combination of celestial and terrestrial cues and how they are weighted in the butterfly's CX is still unknown. Here, we examined how input neurons of the CX, termed TL neurons, combine celestial and terrestrial information. While recording intracellularly from the neurons, we presented a sun stimulus and polarized light to the butterflies as well as a simulated sun and a panoramic scene simultaneously. Our results show that celestial cues are integrated linearly in these cells, while the combination of the sun and a panoramic skyline did not always follow a linear integration of action potential rates. Interestingly, while the sun and polarized light were invariantly weighted between individual neurons, the sun stimulus and panoramic skyline were dynamically weighted when both stimuli were simultaneously presented. Taken together, this dynamic weighting between celestial and terrestrial cues may allow the butterflies to flexibly set their cue preference during navigation.

T1 - Variation in nectar quality across 34 grassland plant species JF - Plant Biology N2 - Floral nectar is considered the most important floral reward for attracting pollinators. It contains large amounts of carbohydrates besides variable concentrations of amino acids and thus represents an important food source for many pollinators. Its nutrient content and composition can, however, strongly vary within and between plant species. The factors driving this variation in nectar quality are still largely unclear. We investigated factors underlying interspecific variation in macronutrient composition of floral nectar in 34 different grassland plant species. Specifically, we tested for correlations between the phylogenetic relatedness and morphology of plants and the carbohydrate (C) and total amino acid (AA) composition and C:AA ratios of nectar. We found that compositions of carbohydrates and (essential) amino acids as well as C:AA ratios in nectar varied significantly within and between plant species. They showed no clear phylogenetic signal. Moreover, variation in carbohydrate composition was related to family‐specific structural characteristics and combinations of morphological traits. Plants with nectar‐exposing flowers, bowl‐ or parabolic‐shaped flowers, as often found in the Apiaceae and Asteraceae, had nectar with higher proportions of hexoses, indicating a selective pressure to decelerate evaporation by increasing nectar osmolality. Our study suggests that variation in nectar nutrient composition is, among others, affected by family‐specific combinations of morphological traits. However, even within species, variation in nectar quality is high. As nectar quality can strongly affect visitation patterns of pollinators and thus pollination success, this intra‐ and interspecific variation requires more studies to fully elucidate the underlying causes and the consequences for pollinator behaviour.

Its contribution to coordinating the expression of genes involved in oncogenesis, epithelial identity, DNA repair, and genome stability has been extensively studied and characterized. For SCC, the expression of ∆Np63 is an essential requirement to maintain the malignant phenotype. Additionally, ∆Np63 functionally contributes to the development of cancer resistance toward therapies inducing DNA damage. SCC patients are currently treated with the same conventional Cisplatin therapy as they would have been treated 30 years ago. In contrast to patients with other tumor entities, the survival of SCC patients is limited, and the efficacy of the current therapies is rather low. Considering the rising incidences of these tumor entities, the development of novel SCC therapies is urgently required. Targeting ∆Np63, the transcription factor, is a potential alternative to improve the therapeutic response and clinical outcomes of SCC patients. However, ∆Np63 is considered “undruggable.” As is commonly observed in transcription factors, ∆Np63 does not provide any suitable domains for the binding of small molecule inhibitors. ∆Np63 regulates a plethora of different pathways and cellular processes, making it difficult to counteract its function by targeting downstream effectors. As ∆Np63 is strongly regulated by the ubiquitin–proteasome system (UPS), the development of deubiquitinating enzyme inhibitors has emerged as a promising therapeutic strategy to target ∆Np63 in SCC treatment. This work involved identifying the first deubiquitinating enzyme that regulates ∆Np63 protein stability. Stateof-the-art SCC models were used to prove that USP28 deubiquitinates ∆Np63, regulates its protein stability, and affects squamous transcriptional profiles in vivo and ex vivo. Accordingly, SCC depends on USP28 to maintain essential levels of ∆Np63 protein abundance in tumor formation and maintenance. For the first time, ∆Np63, the transcription factor, was targeted in vivo using a small molecule inhibitor targeting the activity of USP28. The pharmacological inhibition of USP28 was sufficient to hinder the growth of SCC tumors in preclinical mouse models. Finally, this work demonstrated that the combination of Cisplatin with USP28 inhibitors as a novel therapeutic alternative could expand the limited available portfolio of SCC therapeutics. Collectively, the data presented within this dissertation demonstrates that the inhibition of USP28 in SCC decreases ∆Np63 protein abundance, thus downregulating the Fanconi anemia (FA) pathway and recombinational DNA repair. Accordingly, USP28 inhibition reduces the DNA damage response, thereby sensitizing SCC tumors to DNA damage therapies, such as Cisplatin. N2 - ∆Np63 ist ein Hauptregulator der Plattenepithelzellidentität und reguliert mehrere Signalwege, die entscheidend zur Entstehung von Plattenepithelkarzinomen (SCC) beitragen. Sein Beitrag zur Koordination der Expression von Genen, die an der Onkogenese, der epithelialen Identität, der DNA-Reparatur und der Genomstabilität beteiligt sind, wurde umfassend untersucht und charakterisiert. Für SCC ist die Expression von ∆Np63 eine wesentliche Voraussetzung, um den malignen Phänotyp zu erhalten. Darüber hinaus trägt ∆Np63 funktionell zur Entwicklung einer Krebsresistenz gegenüber Therapien bei, die DNA-Schäden induzieren. SCC-Patienten werden derzeit mit der gleichen konventionellen Cisplatin-Therapie behandelt, wie sie vor 30 Jahren behandelt worden wären. Im Gegensatz zu Patienten mit anderen Tumorentitäten ist das Überleben von SCC-Patienten begrenzt und die Wirksamkeit der aktuellen Therapien eher gering. Angesichts der steigenden Inzidenz dieser Tumorentitäten ist die Entwicklung neuer Therapien für das Plattenepithelkarzinom dringend erforderlich. Das Targeting von ∆Np63, dem Transkriptionsfaktor, ist eine potenzielle Alternative zur Verbesserung des therapeutischen Ansprechens und der klinischen Ergebnisse von SCC-Patienten. ∆Np63 gilt jedoch als „nicht medikamentös“. Wie bei Transkriptionsfaktoren häufig beobachtet, bietet ∆Np63 keine geeigneten Domänen für die Bindung von niedermolekularen Inhibitoren. ∆Np63 reguliert eine Vielzahl von verschiedenen Signalwegen und zellulären Prozessen, was es schwierig macht, seiner Funktion entgegenzuwirken, indem es nachgeschaltete Effektoren angreift. Da ∆Np63 stark durch das Ubiquitin-Proteasom-System (UPS) reguliert wird, hat sich die Entwicklung von deubiquitinierenden Enzyminhibitoren als vielversprechende therapeutische Strategie erwiesen, um ∆Np63 bei der Behandlung von Plattenepithelkarzinomen zu bekämpfen. Diese Arbeit beinhaltete die Identifizierung des ersten deubiquitinierenden Enzyms, das die Stabilität des ∆Np63-Proteins reguliert. Hochmoderne SCC-Modelle wurden verwendet, um zu beweisen, dass USP28 ∆Np63 deubiquitiniert, seine Proteinstabilität reguliert und Plattenepithel-Transkriptionsprofile in vivo und ex vivo beeinflusst. Dementsprechend hängt SCC von USP28 ab, um wesentliche Mengen des Np63-Proteinüberflusses bei der Tumorbildung und -erhaltung aufrechtzuerhalten. Zum ersten Mal wurde ∆Np63, der Transkriptionsfaktor, in vivo mit einem niedermolekularen Inhibitor gezielt, der auf die Aktivität von USP28 abzielt. Die pharmakologische Hemmung von USP28 war ausreichend, um das Wachstum von SCC-Tumoren in präklinischen Mausmodellen zu verhindern. Schließlich zeigte diese Arbeit, dass die Kombination von Cisplatin mit USP28-Inhibitoren als neuartige therapeutische Alternative das begrenzt verfügbare Portfolio an SCC-Therapeutika erweitern könnte. Zusammengefasst zeigen die in dieser Dissertation präsentierten Daten, dass die Hemmung von USP28 in SCC die Np63-Proteinhäufigkeit verringert, wodurch der Fanconi-Anämie (FA)-Signalweg und die rekombinatorische DNA-Reparatur herunterreguliert werden. Dementsprechend reduziert die Hemmung von USP28 die Reaktion auf DNA-Schäden und sensibilisiert dadurch SCC- Tumoren für DNA-Schädigungstherapien wie Cisplatin.

T1 - USP28 enables oncogenic transformation of respiratory cells, and its inhibition potentiates molecular therapy targeting mutant EGFR, BRAF and PI3K JF - Molecular Oncology N2 - Oncogenic transformation of lung epithelial cells is a multistep process, frequently starting with the inactivation of tumour suppressors and subsequent development of activating mutations in proto-oncogenes, such as members of the PI3K or MAPK families. Cells undergoing transformation have to adjust to changes, including altered metabolic requirements. This is achieved, in part, by modulating the protein abundance of transcription factors. Here, we report that the ubiquitin carboxyl-terminal hydrolase 28 (USP28) enables oncogenic reprogramming by regulating the protein abundance of proto-oncogenes such as c-JUN, c-MYC, NOTCH and ∆NP63 at early stages of malignant transformation. USP28 levels are increased in cancer compared with in normal cells due to a feed-forward loop, driven by increased amounts of oncogenic transcription factors such as c-MYC and c-JUN. Irrespective of oncogenic driver, interference with USP28 abundance or activity suppresses growth and survival of transformed lung cells. Furthermore, inhibition of USP28 via a small-molecule inhibitor resets the proteome of transformed cells towards a ‘premalignant’ state, and its inhibition synergizes with clinically established compounds used to target EGFR\(^{L858R}\)-, BRAF\(^{V600E}\)- or PI3K\(^{H1047R}\)-driven tumour cells. Targeting USP28 protein abundance at an early stage via inhibition of its activity is therefore a feasible strategy for the treatment of early-stage lung tumours, and the observed synergism with current standard-of-care inhibitors holds the potential for improved targeting of established tumours.

T1 - Unraveling the hidden temporal range of fast β2-adrenergic receptor mobility by time-resolved fluorescence JF - Communications Biology N2 - G-protein-coupled receptors (GPCRs) are hypothesized to possess molecular mobility over a wide temporal range. Until now the temporal range has not been fully accessible due to the crucially limited temporal range of available methods. This in turn, may lead relevant dynamic constants to remain masked. Here, we expand this dynamic range by combining fluorescent techniques using a spot confocal setup. We decipher mobility constants of β\(_{2}\)-adrenergic receptor over a wide time range (nanosecond to second). Particularly, a translational mobility (10 µm\(^{2}\)/s), one order of magnitude faster than membrane associated lateral mobility that explains membrane protein turnover and suggests a wider picture of the GPCR availability on the plasma membrane. And a so far elusive rotational mobility (1-200 µs) which depicts a previously overlooked dynamic component that, despite all complexity, behaves largely as predicted by the Saffman-Delbrück model.

Moreover, several conditions with phenotypes overlapping Usher syndrome have been described. This makes the molecular diagnosis of hereditary deaf-blindness challenging. Here, we performed exome sequencing and analysis on 7 Mexican and 52 Iranian probands with combined retinal degeneration and hearing impairment (without intellectual disability). Clinical assessment involved ophthalmological examination and hearing loss questionnaire. Usher syndrome, most frequently due to biallelic variants in MYO7A (USH1B in 16 probands), USH2A (17 probands), and ADGRV1 (USH2C in 7 probands), was diagnosed in 44 of 59 (75%) unrelated probands. Almost half of the identified variants were novel. Nine of 59 (15%) probands displayed other genetic entities with dual sensory impairment, including Alström syndrome (3 patients), cone-rod dystrophy and hearing loss 1 (2 probands), and Heimler syndrome (1 patient). Unexpected findings included one proband each with Scheie syndrome, coenzyme Q10 deficiency, and pseudoxanthoma elasticum. In four probands, including three Usher cases, dual sensory impairment was either modified/aggravated or caused by variants in distinct genes associated with retinal degeneration and/or hearing loss. The overall diagnostic yield of whole exome analysis in our deaf-blind cohort was 92%. Two (3%) probands were partially solved and only 3 (5%) remained without any molecular diagnosis. In many cases, the molecular diagnosis is important to guide genetic counseling, to support prognostic outcomes and decisions with currently available and evolving treatment modalities.

We investigated hippocampal giant mossy fiber bouton (MFB) AZ architecture in 3D using electron tomography of rapid cryo-immobilized acute brain slices in RIM1α\(^{−/−}\) and wild-type mice. In RIM1α\(^{−/−}\), AZs are larger with increased synaptic cleft widths and a 3-fold reduced number of tightly docked SVs (0–2 nm). The distance of tightly docked SVs to the AZ center is increased from 110 to 195 nm, and the width of their electron-dense material between outer SV membrane and AZ membrane is reduced. Furthermore, the SV pool in RIM1α\(^{−/−}\) is more heterogeneous. Thus, RIM1α, besides its role in tight SV docking, is crucial for synaptic architecture and vesicle pool organization in MFBs.

A1 - Mitesser, Oliver T1 - Tracking the temporal dynamics of insect defoliation by high‐resolution radar satellite data JF - Methods in Ecology and Evolution N2 - Quantifying tree defoliation by insects over large areas is a major challenge in forest management, but it is essential in ecosystem assessments of disturbance and resistance against herbivory. However, the trajectory from leaf-flush to insect defoliation to refoliation in broadleaf trees is highly variable. Its tracking requires high temporal- and spatial-resolution data, particularly in fragmented forests. In a unique replicated field experiment manipulating gypsy moth Lymantria dispar densities in mixed-oak forests, we examined the utility of publicly accessible satellite-borne radar (Sentinel-1) to track the fine-scale temporal trajectory of defoliation. The ratio of backscatter intensity between two polarizations from radar data of the growing season constituted a canopy development index (CDI) and a normalized CDI (NCDI), which were validated by optical (Sentinel-2) and terrestrial laser scanning (TLS) data as well by intensive caterpillar sampling from canopy fogging. The CDI and NCDI strongly correlated with optical and TLS data (Spearman's ρ = 0.79 and 0.84, respectively). The ΔNCDII\(_{Defoliation(A−C)}\) significantly explained caterpillar abundance (R\(^{2}\) = 0.52). The NCDI at critical timesteps and ΔNCDI related to defoliation and refoliation well discriminated between heavily and lightly defoliated forests. We demonstrate that the high spatial and temporal resolution and the cloud independence of Sentinel-1 radar potentially enable spatially unrestricted measurements of the highly dynamic canopy herbivory. This can help monitor insect pests, improve the prediction of outbreaks and facilitate the monitoring of forest disturbance, one of the high priority Essential Biodiversity Variables, in the near future.

Arbequina leaves extract: an integrated in vitro, in silico, and in vivo investigation JF - Metabolites N2 - Olea europaea L. Cv. Arbequina (OEA) (Oleaceae) is an olive variety species that has received little attention. Besides our previous work for the chemical profiling of OEA leaves using LC–HRESIMS, an additional 23 compounds are identified. An excision wound model is used to measure wound healing action. Wounds are provided with OEA (2% w/v) or MEBO\(^®\) cream (marketed treatment). The wound closure rate related to vehicle-treated wounds is significantly increased by OEA. Comparing to vehicle wound tissues, significant levels of TGF-β in OEA and MEBO\(^®\) (p < 0.05) are displayed by gene expression patterns, with the most significant levels in OEA-treated wounds. Proinflammatory TNF-α and IL-1β levels are substantially reduced in OEA-treated wounds. The capability of several lignan-related compounds to interact with MMP-1 is revealed by extensive in silico investigation of the major OEA compounds (i.e., inverse docking, molecular dynamics simulation, and ΔG calculation), and their role in the wound-healing process is also characterized. The potential of OEA as a potent MMP-1 inhibitor is shown in subsequent in vitro testing (IC\(_{50}\) = 88.0 ± 0.1 nM). In conclusion, OEA is introduced as an interesting therapeutic candidate that can effectively manage wound healing because of its anti-inflammatory and antioxidant properties.
