Climate change poses significant challenges to livestock production worldwide. Wherein, it affects communities in developing nations primarily dependent on agriculture and animal husbandry. Its direct and indirect deleterious effects on agriculture and animal husbandry includes aberrant changes in weather patterns resulting in disturbed homeorhetic mechanism of livestock vis a vis indirectly affecting nutrient composition of feed and fodder.

Lessons Learned: Intravenous paricalcitol did not improve the efficacy of pembrolizumab, likely related to the short half-life.
Background: Immunotherapy has limited benefit in the treatment of advanced pancreatic cancer with the tumor microenvironment playing a key role in immune resistance. In preclinical studies, vitamin D receptor (VDR) agonists have been shown to sensitize pancreatic tumors to PD-1 blockade.
Vitamin K-dependent gamma-carboxyglutamic acid protein 1 promotes pancreatic ductal adenocarcinoma progression through stabilizing oncoprotein KRAS and tyrosine kinase receptor EGFR.

Background: Vitamin K-dependent γ-glutamic acid carboxylation (Gla) proteins are calcium-binding and membrane-associated, participating in coagulation, bone turnover, and cancer biology. The molecular function of transmembrane proline-rich Gla proteins (PRRGs) remains unexplored.
Methods: Analysis of pancreatic ductal adenocarcinoma (PDAC) datasets, including transcription profiles, clinical data, and tissue microarrays, was conducted to evaluate PRRG1 expression and its clinical relevance.
Development of an environmentally responsive fluorescent ligand for vitamin D receptor.

Vitamin D receptor (VDR) plays a critical role in regulating multiple biological processes, including bone metabolism and cell differentiation, by mediating transcriptional activation in response to ligand binding. We have constructed an environmentally fluorescent probe 2 for VDR to facilitate real-time observation of its ligand-dependent conformational changes in living cells. This probe 2 was synthesized by introducing a dansyl fluorophore via an ethynyl group at the C11 position of 1α,25(OH)2D3.

Folic acid (FA), with its anti-inflammatory and antioxidant properties, may offer protection against ischemia-reperfusion (IR) injury. This study investigated whether FA safeguards rat kidneys from IR by targeting high mobility group box-1 (HMGB1), a key inflammatory mediator. Fifty adult male Wistar rats were randomly allocated into four groups: control, IR, IR + FA pretreatment, and FA alone.
