Summary: The study discovered that GPV infection and NS1 protein transfection can significantly induce apoptosis in goose embryo fibroblast cells, mediated by the apoptotic pathway involving apoptosis-inducing factors (AIFs) and internal factors that influence the release of AIFs. The results also highlighted the importance of mitochondrial depolarization, ROS content, and cathepsin D activities in influencing apoptosis in GEF cells.

Summary: The study demonstrates a synergy between the small rigid crosslinker plastin and the large flexible crosslinker spectrin in the C. elegans embryo, showing that their combined action stabilizes the actomyosin network in cytokinesis. Co-inhibition of plastin and beta H-spectrin results in cytokinesis failure, highlighting the importance of crosslinker interplay for network integrity.

Summary: This study investigates the role of BNIP3 in white spot syndrome virus (WSSV) infection in mud crabs. The results show that knockdown of SpBNIP3 increases apoptosis rate and Caspase 3 activity, while decreasing mitochondrial membrane potential and autophagy levels. WSSV infection leads to down-regulation of SpBNIP3 and reduces autophagy, which in turn enriches viral copy number.

Summary: The study revealed that PAK5 inhibits apoptosis in breast cancer cells by preventing the nuclear translocation of AIF. PAK5 phosphorylates AIF to inhibit its complex formation with importin β3, leading to decreased nuclear translocation. The expression of PAK5 and AIF in breast cancer is positively correlated with poor patient prognosis, while PAK5 expression is negatively correlated with AIF nuclear translocation.

Summary: This study investigated the role of apoptosis and ferroptosis in nickel oxide nanoparticles (NiONPs)-induced acute lung injury (ALI). The findings showed that NiONPs exposure led to apoptosis and ferroptosis in lung tissues and elevated levels of pro-inflammatory cytokines, neutrophils, and proteins in bronchoalveolar lavage fluid. Further experiments revealed that NiONPs exposure upregulated the expression of activating transcription factor 3 (ATF3) in murine lung tissues and human lung epithelial cells, and cells lacking ATF3 exhibited lower levels of apoptosis and ferroptosis when exposed to NiONPs. These results suggest that ATF3 may serve as a potential therapeutic target and biomarker for NiONPs-associated ALI.

Summary: Liver diseases have become a major health concern for people living with HIV-1 (PLWH) treated with combination antiretroviral therapy (cART). Through studying a humanized mouse model, it was discovered that chronic HIV-1 infection with cART treatment resulted in hepatitis and liver fibrosis, associated with accumulation of M2-like macrophages, elevated TGF-β and IFN signaling in the liver. Similar changes were found in blood specimens from PLWH. Therefore, inhibiting IFN-I signaling or M2-like macrophages may provide a novel therapeutic strategy for treating HIV/cART-associated liver diseases.

Summary: This study presents a 2D vertex model of thyroid growth, angiogenesis, and folliculogenesis that accurately simulates the differential growth of epithelial cells, migration of endothelial cells, and formation of follicular lumens during thyroid embryonic development. The model highlights the importance of cellular adhesion, movement, and polarization in organogenesis, providing valuable insights into the roles of these processes in thyroid function. By incorporating theoretical and experimental approaches, in silico models like the one described in this study have the potential to advance the fields of developmental biology and regenerative medicine.

Summary: With the rapid development of nanotechnology, the potential adverse health effects of nanoparticles have become global concerns. This study investigated the effects of nickel nanoparticles (Nano-Ni) and titanium dioxide nanoparticles (Nano-TiO2) on autophagy and apoptosis levels in human bronchial epithelial cells. The results showed dysregulation of autophagy and apoptosis-associated proteins in cells exposed to Nano-Ni, while Nano-TiO2 had no significant effects. Nano-Ni exposure led to nuclear accumulation of HIF-1a and decreased phosphorylation of mTOR, and inhibition of HIF-1a abolished Nano-Ni-induced decreased phosphorylation of mTOR. Moreover, Nano-Ni-induced autophagy played a protective role against Nano-Ni-induced apoptosis.

Summary: Transcytosis is a specialized form of transport where extracellular cargo is endocytosed, transported through the cytoplasm in vesicles, and secreted at a different plasma membrane surface. It allows membrane-impermeable macromolecules to pass through cells and become accessible to adjacent cells and tissues. Moreover, transcytosis also plays a role in redistributing plasma membrane proteins and lipids to different regions of the cell surface.

Summary: Vasculogenic mimicry (VM) refers to the ability of aggressive tumor cells to develop pseudovascular structures without endothelial cells. This study investigated the role of hypoxia and PARP inhibition in VM. Results showed that the PARP inhibitor olaparib improved pericyte coverage and reduced metastasis in uveal melanoma xenografts with VM. PARP inhibition and hypoxia induced changes in melanoma tube formation and gene expression related to vasculogenesis, enhancing the endothelial-like phenotype of VM+ melanoma cells. Overall, PARP inhibitors have the potential to modulate VM characteristics and reduce metastatic spread in melanoma.

Summary: This review examines the mechanisms of angiogenesis in brain development, brain vascular malformations, and brain tumors. The CNS critically relies on the formation and proper function of its vasculature during different stages, and angiogenesis plays a key role in vascular-dependent brain diseases. However, the exact molecular pathways and mechanisms underlying angiogenesis in the CNS are not fully understood.

Summary: Airway epithelial repair requires a shift from glycolysis to fatty acid oxidation. Promoting fatty acid oxidation enhances epithelial differentiation, offering potential therapeutic options. Defects in mucociliary clearance or barrier integrity lead to recurrent infections and chronic inflammation in the airway epithelium.

Summary: Astrocytes, a type of glial cells in the brain, primarily rely on glycolysis for energy production, indicating glucose as their main metabolic precursor. However, recent studies have shown that astrocytes also have the ability to metabolize fatty acids, and this metabolic pathway may play a role in preserving mitochondrial function and cognitive performance.

Summary: Although the angiogenic effect of VEGF-B is not well understood, inhibitors of VEGF-B are being used in the treatment of neovascular diseases. In this study, we reveal a previously unrecognized function of VEGF-B as an endogenous inhibitor of angiogenesis by inhibiting the FGF2/FGFR1 pathway. We found that VEGF-B binds to FGFR1, induces FGFR1/VEGFR1 complex formation, suppresses FGF2-induced Erk activation, and inhibits FGF2-driven angiogenesis and tumor growth.
