LncRNA Gm35585 transcriptionally activates the peroxidase EHHADH against diet-induced fatty liver.

Metabolic-dysfunction-associated steatotic liver disease is one of the most common chronic liver diseases worldwide and has no approved treatment thus far. Here we report that the hepatic overexpression of Gm35585, a novel lncRNA downregulated in the livers of mice fed a high-fat diet, is functionally important in alleviating hepatic lipid accumulation pathologies. Gm35585 activates the peroxisome proliferator-activated receptor α (PPARα) signaling pathway and promotes the expression of downstream PPARα-target gene, enoyl-CoA hydratase and 3-hydroxyacyl CoA dehydrogenase (EHHADH), which is one of the four enzymes of the peroxisomal β-oxidation pathway.

Safe and Balanced: A Framework for Constrained Multi-Objective Reinforcement Learning.

In numerous reinforcement learning (RL) problems involving safety-critical systems, a key challenge lies in balancing multiple objectives while simultaneously meeting all stringent safety constraints. To tackle this issue, we propose a primal-based framework that orchestrates policy optimization between multi-objective learning and constraint adherence. Our method employs a novel natural policy gradient manipulation method to optimize multiple RL objectives and overcome conflicting gradients between different tasks, since the simple weighted average gradient direction may not be beneficial for specific tasks' performance due to misaligned gradients of different task objectives.
