Interaction of PASTICCINO2 with Golgi anti-apoptotic proteins confers resistance to endoplasmic reticulum stress and is dependent on very-long-chain fatty acids.

The endoplasmic reticulum (ER) is crucial for maintaining cell homeostasis because it is the primary site for synthesizing secreted and transmembrane proteins and lipids. The unfolded protein response (UPR) is activated to restore the homeostasis of the ER when it is under stress; however, the relationship between lipids and the ER stress response in plants is not well understood. Arabidopsis GOLGI ANTI-APOPTOTIC PROTEINS (GAAPs) are involved in resisting ER stress, and in this study, we found that PASTICCINO2 (PAS2), which is involved in very-long-chain fatty acid (VLCFA) synthesis, interacts with GAAPs and INOSITOL REQUIRING ENZYME 1.

With a specific focus on addressing the unique needs of HI children, the design strategies and interaction strategies were derived from the previous studies.

VCAM-1 mediates proximal tubule-immune cell cross talk in failed tubule recovery during AKI-to-CKD transition.

Studies in animal models have suggested a linkage between the inflammatory response to injury and subsequent nephron loss during the acute kidney injury (AKI) to chronic kidney disease (CKD) transition. Failure of normal repair during the CKD transition correlates with de novo expression of vascular cell adhesion protein-1 (VCAM-1) by a subset of injured proximal tubule cells. This study identified the role of VCAM-1 expression in promoting the failed repair state.

Effect of parenteral lipids on essential fatty acid deficiency in pediatric intestinal failure: A retrospective cohort study.

Background: Pediatric patients with intestinal failure require long-term parenteral nutrition owing to impaired enteral nutrition absorption. A potential complication is essential fatty acid deficiency (EFAD), resulting from decreased linoleic and α-linolenic acid concentrations and defined by an increased triene:tetraene ratio (TTR; Mead acid:arachidonic acid). Historically, soybean oil lipid emulsion (SOLE) was the only commercially available parenteral lipid in the United States.

GGNBP2 regulates histone ubiquitination and methylation in spermatogenesis.

Gametogenetin binding protein 2 (GGNBP2) was indispensable in normal spermatids for transformation into mature spermatozoa in mice, and when Gametogenetin binding protein 2 is bound to BRCC36 and RAD51, the complex participates in repairing DNA double-strand breaks (DSB) during the meiotic progression of spermatocytes. Ggnbp2 knockout resulted in the up-regulation of H2A and down-regulation of H2B in GC-2 cells (mouse spermatogonia-derived cell line) and postnatal day 18 testis lysate. Our results also demonstrated that Gametogenetin binding protein 2 inducedASXL1 to activate the deubiquitinating enzyme BAP1 in deubiquitinating H2A, while Gametogenetin binding protein 2 knockout disrupted the interaction between ASXL1 and BAP1, resulting in BAP1 localization change.

Leucosceptrane sesterterpenoids from Tibetan Leucosceptrum canum and their immunosuppressive activity.

Substrate Channeling in Compartmentalized Nanoreactors.

Thermo- and photoresponsive nanoreactors based on shell cross-linked micelles (SCMs) for the rhodium-catalyzed asymmetric transfer hydrogenation (ATH) of ketones have been developed from poly(2-oxazoline) triblock terpolymers. The nanoreactors incorporate thermoresponsive poly(2-isopropyl-2-oxazoline) as the hydrophilic corona and are covalently cross-linked with a photoswitchable spiropyran molecule. UV irradiation or changes in temperature trigger morphology switching of the polymer-based nanoreactors that alters the hydrophobicity in separate layers of the SCMs, resulting in dynamic substrate selectivity of the ATH in water.
