Cardiomyocyte-Restricted Deletion of PPARβ/δ in PPARα-Null Mice Causes Impaired Mitochondrial Biogenesis and Defense, but No Further Depression of Myocardial Fatty Acid Oxidation... by Jian Liu, Peiyong Wang, Lan He, Yuquan Li, Jinwen Luo, Lihong Cheng, Qianhong Qin, Lawrence A. Brako, Woo-kuen Lo, William Lewis, Qinglin Yang

“…However, previous studies demonstrated that cardiomyocyte-restricted PPARβ/δ deficiency in mice leads to severe cardiac pathological development, whereas global PPARα knockout shows a benign cardiac phenotype. It is unknown whether a PPARα-null background would alter the pathological development in mice with cardiomyocyte-restricted PPARβ/δ deficiency. …”

Invasion of pancreatic ductal epithelial cells by Enterococcus faecalis is mediated by fibronectin and enterococcal fibronectin-binding protein A by Munefumi Shimosaka, Jumpei Kondo, Mamika Sonoda, Rui Kawaguchi, Emika Noda, Kaho Nishikori, Asuka Ogata, Shinji Takamatsu, Ken Sasai, Hirofumi Akita, Hidetoshi Eguchi, Yoshihiro Kamada, Shigefumi Okamoto, Eiji Miyoshi

“…Mechanistically, bacterial expression of enterococcal fibronectin-binding protein A (EfbA) was correlated with adhesive potential of E. faecalis strains. Knockout of fibronectin 1, a binding partner of EfbA, in iPDECs resulted in suppressed E. faecalis adhesion and invasion, suggesting the importance of the EfbA-fibronectin axis in infection of pancreatic ductal epithelial lineage cells. …”

Betacoronaviruses Differentially Activate the Integrated Stress Response to Optimize Viral Replication in Lung-Derived Cell Lines by David M. Renner, Nicholas A. Parenti, Nicole Bracci, Susan R. Weiss

“…Interestingly, genetic ablation of growth arrest and DNA damage-inducible protein (GADD34) expression, an inducible protein phosphatase 1 (PP1)-interacting partner targeting eIF2α for dephosphorylation, did not significantly alter HCoV-OC43 or SARS-CoV-2 replication, while siRNA knockdown of the constitutive PP1 partner, constitutive repressor of eIF2α phosphorylation (CReP), dramatically reduced HCoV-OC43 replication. Combining GADD34 knockout with CReP knockdown had the maximum impact on HCoV-OC43 replication, while SARS-CoV-2 replication was unaffected. …”
