Phospholipase C-β3 is dispensable for vascular constriction but indispensable for vascular hyperplasia.

Angiotensin II (AngII) induces the contraction and proliferation of vascular smooth muscle cells (VSMCs). AngII activates phospholipase C-β (PLC-β), thereby inducing Ca mobilization as well as the production of reactive oxygen species (ROS). Since contraction is a unique property of contractile VSMCs, signaling cascades related to the proliferation of VSMCs may differ.

Scyllatoxin-based peptide design for E. coli expression and HIV gp120 binding.

Targeting the hydrophobic Phe43 pocket of HIV's envelope glycoprotein gp120 is a critical strategy for antiviral interventions due to its role in interacting with the host cell's CD4. Previous inhibitors, including small molecules and CD4 mimetic peptides based on scyllatoxin, have demonstrated significant binding and neutralization capabilities but were often chemically synthesized or contained non-canonical amino acids. Microbial expression using natural amino acids offers advantages such as cost-effectiveness, scalability, and efficient production of fusion proteins.

Estrogen-related receptor alpha promotes thyroid tumor cell survival via a tumor subtype-specific regulation of target gene networks.

Mortalin (encoded by HSPA9) is a mitochondrial chaperone often overexpressed in cancer through as-yet-unknown mechanisms. By searching different RNA-sequencing datasets, we found that ESRRA is a transcription factor highly correlated with HSPA9 in thyroid cancer, especially in follicular, but not C cell-originated, tumors. Consistent with this correlation, ESRRA depletion decreased mortalin expression only in follicular thyroid tumor cells.

SETDB1 deletion causes DNA demethylation and upregulation of multiple zinc-finger genes.

Background: SETDB1 (SET domain bifurcated-1) is a histone H3-lysine 9 (H3K9)-specific methyltransferase that mediates heterochromatin formation and repression of target genes. Despite the assumed functional link between DNA methylation and SETDB1-mediated H3K9 trimethylations, several studies have shown that SETDB1 operates autonomously of DNA methylation in a region- and cell-specific manner. This study analyzes SETDB1-null HAP1 cells through a linked methylome and transcriptome analysis, intending to explore genes controlled by SETDB1-involved DNA methylation.
