Anginex is a novel artificial peptide that can inhibit angiogenesis. AdNT4-anginex was constructed by inserting the artificial anginex gene into a recombinant adenoviral vector. We demonstrated that AdNT4-anginex inhibited migration of human endothelial cells, angiogenesis and tumor growth in in vitro and in vivo studies. Tumor growth of human H22 hepatoma in mice was inhibited after AdNT4-anginex treatment for 4 weeks, and a significant decrease in tumor size was observed as compared with the control group. Overall, these studies indicate that AdNT4-anginex is an effective anti-tumor agent, and deserves more attention and research.

Importance: Cardiovascular disease (CVD) and cancer are the leading causes of mortality in the US. Large-scale population-based and mechanistic studies support a direct effect of CVD on accelerated tumor growth and spread, specifically in breast cancer.
Objective: To assess whether individuals presenting with advanced breast cancers are more likely to have prevalent CVD compared with those with early-stage breast cancers at the time of diagnosis.

The present study aimed to unveil the gastroprotective potential of Vaccinium macrocarpon (VM) extract and its mechanism of action against indomethacin (INDO)-induced gastric ulcers in rats. To achieve this goal, rats were pretreated with either omeprazole (20 mg/kg) or VM (100 mg/kg) orally for 14 consecutive days. Gastric tissue samples were collected and various parameters were evaluated to understand the mechanism of VM's action, including the levels of superoxide dismutase, malondialdehyde, glutathione, CAT and transforming growth factor beta (TGF-β), as well as the mRNA expression levels of tumour necrosis factor alpha, interleukin 1 beta, nuclear factor kappa B (NF-κB) and inhibitor kappa B (IκB).

Tumor cell-intrinsic signaling pathways can drastically affect the tumor immune microenvironment, promoting tumor progression and resistance to immunotherapy by excluding immune-cell populations from the tumor. Several tumor cell-intrinsic pathways have been reported to modulate myeloid-cell and T-cell infiltration creating "cold" tumors. However, clinical evidence suggests that excluding cytotoxic T cells from the tumor core also mediates immune evasion.

Pancreatic ductal adenocarcinoma (PDAC) remains one of the deadliest solid cancers; thus, identifying more effective therapies is a major unmet need. In this study, we characterized the super enhancer (SE) landscape of human PDAC to identify drivers of the disease that might be targetable. This analysis revealed MICAL2 as a super enhancer-associated gene in human PDAC, which encodes the flavin monooxygenase MICAL2 that induces actin depolymerization and indirectly promotes SRF transcription by modulating the availability of serum response factor coactivators myocardin-related transcription factors (MRTF-A and MRTF-B).

Ten cytochalasin derivatives, including six new methylthioether-containing chaetoglobosins (thiochaetoglobosins A-F, ), a new related congener (18-nor-prochaetoglobosin II, ), and three known unsulfured counterparts (), were isolated and identified from AS-506, an endozoic fungus isolated from a deep-sea sponge, which was collected from Magellan Seamounts in the Western Pacific Ocean. Their structures were determined by extensive interpretation of the spectroscopic and X-ray crystallographic data, as well as by ECD calculations. Structurally, thiochaetoglobosins A-F () represent the first examples of chaetoglobosin derivatives containing a methylthioether group in the molecules, while 18-nor-prochaetoglobosin II () is the first 18-nor-chaetoglobosin derivative.
