Summary: The study demonstrated the regulatory role of PAQR9 in hepatic ketogenesis and showed that deletion of PAQR9 attenuated ketogenesis and fatty acid oxidation during fasting by decreasing PPARa protein stability and competing with HUWE1 for interaction with PPAR alpha.

Summary: mRNA display is a powerful technique for discovering high-affinity ligands, but limited cyclization chemistries are compatible with it. Here, we demonstrate that peptides containing tyrosine and cysteine can be rapidly cyclized using the copper-dependent oxidase tyrosinase. This tyrosinase-mediated cyclization combined with mRNA display enables the discovery of potent macrocyclic ligands for MAGE-A4 with nanomolar IC50 values, showing a significant advantage over noncyclized analogues.

Summary: Fasting induces lipid accumulation in the liver, with endogenous dicarboxylic acids playing a role in controlling mitochondrial beta-oxidation. Excessive beta-oxidation of dicarboxylic acids leads to succinate production, which suppresses mitochondrial beta-oxidation, promotes hepatic lipid deposition, and identifies cross talk between peroxisomal and mitochondrial fatty acid oxidation.

Summary: The study found that fasting-induced β-OHB and FGF21 coordinately regulate oxidative stress response gene expression in the heart by modulating the expression of PPARα and oxidative stress response genes. Additionally, the absence of FGF21 exacerbates the expression levels of β-OHB and PPG1α in the heart.

Summary: This study reports a method to identify covalent cyclic peptide inhibitors in mRNA display. By combining co- and post-translational library diversification strategies, cyclic libraries with reactive dehydroalanines (Dhas) were created and used for selections against two model targets. The most potent hits showed low nanomolar inhibitory activities and disrupted known protein-protein interactions with their selected targets. Overall, this study establishes Dhas as electrophiles for covalent inhibition and demonstrates the synergy of separate library diversification methods in mRNA display for novel applications like covalent inhibitor discovery.

Summary: Lipin 1 regulates cellular lipid homeostasis through roles in glycerolipid synthesis and transcriptional coactivation, but its deficiency can lead to episodic disease symptoms triggered by metabolic stress. Fasting exacerbates the deleterious effects of lipin 1 deficiency on metabolic homeostasis, mainly through its influence on mRNA splicing in the liver.

Summary: Alternate day fasting (ADF) attenuated high-fat diet (HFD)-induced nonalcoholic fatty liver disease (NAFLD) in mice by reducing hepatic inflammation and lipid accumulation. Fasting increased expression of serum and hepatic fibroblast growth Factor 21 (Fgf21) and prevented FFA-induced lipid storage in hepatocytes. Refeeding inhibited the increase in Fgf21 expression induced by fasting, suggesting a potential role of PPAR alpha/Fgf21 signaling in protecting against NAFLD.

Summary: Sodium-glucose co-transporter 2 inhibitors have shown potential anticancer activities in selected cancer types, possibly through mechanisms like reducing glucose uptake into cancer cells and modulating signaling pathways. Clinical findings suggest that canagliflozin and dapagliflozin may have anticancer properties in patients with liver and colon cancers.

Summary: <br>Gene expression changes are inevitable in cancer development, and this study aimed to investigate the potential of rectal swab specimens as a tool for detecting dysregulation of cancer stem cells and evaluating it as a screening method. The study found that a panel of Oct4 and CD26 could distinguish CRC from normal and polyp patients, while a panel of c-MYC and CXCR4 may identify polyp and CRC patients from normal individuals.

Summary: This study investigated the potential of DPP4-inhibitors in treating CRC patients, and found that DPP4-inhibitor treatment was associated with a significantly better 5-year prognosis following curative resection compared to metformin treatment. The study also showed an association between patient prognosis and immune cell population features, suggesting that immune cell profiles may serve as a biomarker for predicting patient prognosis in response to DPP4-inhibitor treatment.

Summary: MiR-509-3p is overexpressed in colorectal cancer and associated with aggressive disease presentation. It inhibits the expression of tumor suppressor PHLPP2 by directly binding to its 3'UTR. The high expression of miR-509-3p in tumor-adjacent normal tissues is associated with poor prognosis in CRC.

Summary: Non-alcoholic fatty liver disease (NAFLD) is a common chronic liver disease that is increasing worldwide, and it is associated with colorectal polyps. This study aimed to investigate the potential of serum microRNAs (miRNAs) in identifying NAFLD in colorectal polyp patients. The results showed that a serum miRNA panel composed of four miRNA pairs significantly identified NAFLD in colorectal polyp patients, and its performance improved when patients with other concurrent metabolic disorders were removed from the analysis. The serum miRNA panel could be a potential diagnostic biomarker for screening NAFLD in colorectal polyp patients for early diagnosis and prevention of disease progression.

Summary: Mitochondria are the central metabolic hubs in cells, relying on proteins encoded by nuclear DNA and mitochondrial DNA (mtDNA) for their function. The maintenance and distribution of mtDNA are crucial for proper mitochondrial function and are associated with mitochondrial diseases. mtDNA is organized into nucleoids that dynamically move and interact with each other. The replication and distribution of mtDNA nucleoids are regulated by the complex interplay of mitochondrial dynamics, ER-mitochondria contact sites, and cytoskeletal networks.

Summary: The overexpression of TPD52 is associated with the emergence of neuroendocrine prostate cancer (NEPC). TPD52 activates the NF-kappa B - STAT3 axis to induce neuroendocrine differentiation (NED) of prostate cancer cells. Therapeutic targeting of TPD52 is important for the treatment of prostate cancer.
