Seltmann et al. discovered that the transmembrane protein CLCA2 is transported to the nucleus of keratinocytes via extracellular vesicles (EVs). Nuclear CLCA2 promotes expression of Wnt target genes and is required for the suppression of keratinocyte migration and for survival of these cells under hyperosmotic stress conditions.

Hiebert et al. used a collagen peptide sensor to visualize lysyl oxidase-dependent collagen formation and remodeling during wound healing. The probe selectively detects newly produced or remodeling collagen, but not matured collagen fibers, and can be applied for in vivo wound imaging and for discerning differential remodeling in mice with altered collagen dynamics.  

The orgaizing committee of the IMHS Seminar Series "The New Generation Scientists Invite" is pleased to invite you to the first Seminar held by Dr. Jürgen Knoblich, who pioneered organoid research and is the current director of the IMBA in Vienna. The Seminar will take place on Tuesday, 27.02.2024, at 10:30, in the seminar room HPM H33.

Cords and colleagues report a spatial resolved single-cell imaging mass cytometry analysis of cancer-associated fibroblasts (CAFs) in a non-small cell lung cancer (NSCLC) cohort of 1’070 patients. Their data identify phenotypic and spatial features of CAFs that are associates with patient outcome in NSCLC.

The ETH student association VSETH has recently awarded Prof. Helmuth Gehart with the Golden Owl for best teaching in the Department of Biology, ETH ZUrich, in 2023.

Authors identify TRIM21 as a negative regulator of liver steatosis in nonalcoholic steatohepatitis (NASH) and provides mechanistic insights into an immunometabolic crosstalk that limits fatty acid synthesis and fructose metabolism during metabolic stress. Thus, providing new insights for therapeutic opportunity to treat NASH.

Gurri et al. found that the NRF3 protein is downregulated or even absent in invasively growing cancer cells of non-melanoma skin cancer (NMSC) patients. NRF3-deficient cancer cells showed enhanced malignancy due to the upregulation of the unfolded protein response regulator HSPA5, which was found as potential NRF3 interactor. Pharmacological inhibition or knock-down of HSPA5 rescued the malignant features of NRF3-deficient cells, suggesting HSPA5 as promising target for the treatment of NMSC.

The swiss cancer league have awarded Prof. Nicola Aceto with the Robert-Wenner Prize, an award for young cancer researchers, for his research on cancer metastasis.

Prof. Judi Allen, University of Manchester, UK. Hosts: Prof. Manfred Kopf and Prof. Sabine Werner.

Sänger et al. found that hyperosmotic stress induces expression of serine protease 35 (PRSS35) in skin fibroblasts, affecting the extracellular matrix proteome and limiting cell proliferation. The in vivo relevance of these findings is reflected by the co-expression of PRSS35 and its binding partners in human skin wounds. The results identify PRSS35 as a key regulator of the matrisome under hyperosmotic stress conditions.

High-resolution temporal analysis of β-cells reveals a role of FoxM1 in protein synthesis and mitochondrial activity during metabolic stress.

Guccini et al. showed that ketohexokinase, the rate-limiting enzyme of fructose metabolism, is a driver of pancreatic ductal adenocarcinoma (PDAC) development.

Using single-cell and spatial proteomics data, Cords and colleagues usuggest a novel classification system for cancer-associated fibroblasts (CAFs) that can be used for the comparison of CAF types across cancer types and studies, contributing in inderstanding the functional role of this cell type.

Recently published eLife paper by the Corn group (IMHS) demonstrates that using CRISPR-​Cas9 gene-​editing to insert transcription factor binding sites can increase transcriptional activity and expression of Hemoglobin A2.

Vatandaslar et al. establish a new viP-CLIP method to  identify physiologically relevant RNA binding protein targets by finding a factor implicated in the negative feedback regulation of cholesterol biosynthesis.

Saini et al. showed that: EPCAM-high cells from metastatic biopsies can propagate breast cancer in vivo; resistance to EMT sustains tumorigenesis and metastatic spread of the human disease; irreversible EMT results in restrained tumorigenic potential in clonal subsets.
