(Submitter supplied) Human pluripotent stem cells (hPSCs) tend to acquire genetic aberrations upon culture in vitro. Common aberrations are mutations in the tumor suppressor TP53, suspected to confer a growth-advantage to the mutant cells. However, their full impact in the development of malignant features and safety of hPSCs for downstream applications is yet to be elucidated. Here, we knock-out TP53 in hPSCs using CRISPR-Cas9 and compare them with isogenic wild-type hPSCs and human germ cell tumor lines as models of malignancy. more...

(Submitter supplied) As ontogeny does not recapitulate phylogeny and little developmental restraint exists prior to gastrulation, early mammalian development differs significantly between species. A prime example is the temporal difference in the first emergence of extra-embryonic mesenchymal cells (ExMC) between mouse and human. Here, we report a fast and efficient in vitro cell model of human ExMC formation from induced pluripotent stem cells. more...

(Submitter supplied) Tertiary lymphoid structures (TLSs) are formed in many cancer types and have been correlated with better prognosis and response to immunotherapy. In liver cancer, TLSs have been reported to be pro-tumorigenic as they harbor tumor progenitor cells and nurture their growth. The processes involved in TLS development and acquisition of pro- or anti-tumorigenic phenotype in cancer are largely unknown. RORc expressing immune cells have been previously implicated in TLS formation, however we find that they are not necessary for TLS neogenesis in the context of liver inflammation. more...

(Submitter supplied) Sepsis-induced acute lung injury (ALI) is prevalent in septic patients and has a high mortality rate. Considering ALI’s close link to sepsis, we used a Pseudomonas aeruginosa (PA) pneumonia-induced sepsis mouse model to investigate alveolar microenvironment alterations and lung injury post-sepsis. Peptidyl arginine deiminase (PADI) 2 and PADI4 are highly expressed in immune cells, and play substantial roles in the immune response to sepsis, but their specific functions remain unclear.We employed single-cell RNA sequencing (scRNA-seq) technology to map immune cell populations in bronchoalveolar lavage fluid (BALF) cells from Wild type (WT) and Padi2 and Padi4 double knock-out (DKO)mice in PA pneumonia-induced sepsis and sham conditions.

(Submitter supplied) To investigate how gradual differences in the tight junction formation could be linked to an altered gene expression, wildtype and PALS1 knockout cell lines were grown under non-confluent and in 3D cyst cultures. After preparation of the mRNA samples, mRNASeq was performed. Normalized gene expression data was then was analyzed for differentially expressed genes, and GO-Term enrichment studies were used to elucidate involved pathways.

(Submitter supplied) We apply ribosome profiling here to assess the role of eIF2A in translation initiation. For this we test the change in translation efficiency between HeLa control and eIF2A-KO cells, however we do not find any transcript to depend on eIF2A. Since eIF2A is thought to take over the function of eIF2 when eIF2 is inhibited, we also test conditions where the integrated stress response is activated, thereby leading to eIF2 inactivation. more...

(Submitter supplied) Transcription-coupled DNA repair (TCR) removes bulky DNA lesions impeding RNA polymerase II (RNAPII) transcription. Recent studies have outlined the stepwise assembly of TCR factors CSB, CSA, UVSSA, and TFIIH around lesion-stalled RNAPII. However, the mechanism and factors required for the transition to downstream repair steps, including RNAPII removal to provide repair proteins access to the DNA lesion, remain unclear. more...

(Submitter supplied) Unfolded protein response (UPR) is a central intracellular stress response pathway that is hijacked by tumor cells for their survival. However, how activation of UPR in cancer cells may shape the tumor microenvironment (TME) remains largely unexplored. Here, we investigated the potential role of IRE1α signaling on modulation of TME dynamics in prostate cancer (PCa). We found that IRE1α is increased in PCa patient tumors and genetic inhibition of IRE1α in syngeneic mouse PCa models, as well as in an orthotopic model, dramatically reduced tumor growth. more...

(Submitter supplied) The link between DNA methylation and neurodevelopmental disorders is well established. However, how DNA methylation is fine-tuned – ensuring precise gene expression and developmental fidelity – remains poorly understood. PROSER1, a known TET2 interactor, was recently linked to a severe neurodevelopmental disorder. Here, we demonstrate that PROSER1 interacts with all TET enzymes and stabilizes chromatin-bound TET-OGT-PROSER1-DBHS (TOPD) complexes, which regulate DNA demethylation and developmental gene expression. more...

(Submitter supplied) In melanoma, lymphangiogenesis correlates with metastasis and poor prognosis and promotes immunosuppression. However, it also potentiates immunotherapy by supporting trafficking of immune cells. Lymphatic endothelial cells (LECs) are highly plastic cells that shape their phenotype according to distinct microenvironments, which likely define their functional properties, such as immunomodulation. Here, we show in a lymphangiogenic murine melanoma model that LECs upregulate the enzyme Ch25h, which catalyzes the formation of 25-hydroxycholesterol (25-HC) from cholesterol and plays important roles in regulating lipid metabolism, gene expression, and immune activation. more...

(Submitter supplied) Sp140 is a lymphocytic-restricted protein, an epigenetic reader working as a corepressor of genes implicated in inflammation and orchestrating macrophage transcriptional programs to maintain cellular identity. Reduced Sp140 expression is associated both to autoimmune diseases and blood cancer. However, the molecular mechanisms that link Sp140 altered protein levels to detrimental effects on the immune response and cellular growth, as well as the interactors through which Sp140 promotes gene silencing, remain elusive. more...

(Submitter supplied) Canonically PD-L1 functions as the inhibitory immune checkpoint on cell surface. Recent studies observed PD-L1 expression in the nucleus of cancer cells. But the biological function of nuclear PD-L1 (nPD-L1) in tumor growth and antitumor immunity is unclear. Here we enforced nPD-L1 expression and established stable cells. nPD-L1 suppressed tumorigenesis and aggressiveness in vitro and in vivo. Compared with PD-L1 deletion, nPD-L1 expression repressed tumor growth and improved survival more significantly in immunocompetent mice. more...

(Submitter supplied) The prospect of repairing the heart after a myocardial infarction by promoting cardiomyocyte proliferation has gained momentum from studies showing the heart's regenerative ability in fish, amphibians and neonatal mammals. Despite evidence of varying cardiomyocyte proliferation rates among species, the molecular mechanisms driving cardiomyocyte cell cycle re-entry remain insufficiently understood. In this study, we employed spatial transcriptomics and identified high-mobility group AT-hook 1a (Hmga1a) as being upregulated in cardiomyocytes of the injury border zone in zebrafish, but not in mice. more...

(Submitter supplied) SETDB1 is a major H3K9 methyltransferase. It contains a unique Triple Tudor Domain (3TD) which specifically bind the dual modification of H3K14ac in the presence of H3K9me1/2/3. In this study, we explored the role of the 3TD H3K14ac interaction in the H3K9 methylation activity by SETDB1. We generated the 3TD binding reduced F332A mutant and demonstrate in biochemical methylation assays on recombinant nucleosomes containing H3K14ac analogs, that H3K14 acetylation is crucial for the 3TD mediated recruitment of SETDB1. more...
