PXDN Reduces Autophagic Flux in Insulin-Resistant Cardiomyocytes via Modulating FoxO1

Scientists report the suppression of cell viability and autophagic flux, as shown by autophagosomes accumulation and increased expression level of LC3-II and p62 in cultured H9C2 and human AC16 cells treated with 400 μM palmitate acid for 24 h.

POU2F2 Regulates Glycolytic Reprogramming and Glioblastoma Progression via PDPK1-Dependent Activation of PI3K/AKT/mTOR Pathway

Researchers identified that the highly expressed POU Class Homeobox 2 (POU2F2) significantly correlated with poor prognosis of glioblastoma patients. POU2F2 promoted cell proliferation and regulated glycolytic reprogramming.

PD-L1 Signaling on Human Memory CD4+ T Cells Induces a Regulatory Phenotype

Researchers demonstrated that programmed death cell receptor 1 (PD-1) ligation on human CD25-depleted CD4+ T cells, combined with CD3/TCR stimulation, induced their conversion into highly suppressive T cells.
