Article Abstract
Background: Hepatocellular carcinoma (HCC) is the most common primary malignancy. Peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PPARGC1A) plays a crucial role in regulating the biogenesis of mitochondria. We aimed to assess the association between PPARGC1A polymorphisms and HCC risk in a Moroccan population.
Methods: In this case-control study, 147 patients with HCC and 147 controls without pre-existing liver disease were matched for ethnicity. TaqMan SNP allelic discrimination assays were used for genotyping of PPARGC1A rs8192678 and rs12640088 polymorphisms.
Results: The result revealed that individuals with the GA/AA genotypes for rs8192678 had a significantly higher risk of HCC compared to those with the GG genotype (OR=6.68; P<0.0001, and OR=9.78; P<0.0001, respectively). In particular, the A allele of rs8192678 was over-represented in HCC patients compared to controls (40% versus 12%, P<0.0001, respectively). With respect to PPARGC1A rs12640088 variant, two genetic models (codominant and dominant) were tested to explore any potential variations in the distribution of SNP A>C among HCC cases and control subjects group. Overall, no significant association between rs12640088 and HCC was found (P>0.05). Interestingly, a significantly higher level of aspartate aminotransferase was observed in HCC patients with GG-GA genotypes (280 IU/L) compared to those with GG genotype (164 IU/L) at rs8192678 (P=0.0019).
Conclusion: Our results suggest that the PPARGC1A rs8192678 polymorphism is associated with an increased risk of HCC in Moroccan population and may serve as a prognostic marker for liver cancer.

RNF128 regulates the adaptive metabolic response to fasting by modulating PPARα function.

Peroxisome proliferator-activated receptor alpha (PPARα) is a crucial transcriptional factor that regulates fatty acid β-oxidation and ketogenesis in response to fasting. However, the mechanisms underlying PPARα function remain unclear. This study identified a novel PPARα-binding protein-RING finger protein 128 (RNF128)-that facilitates PPARα polyubiquitination, resulting in the degradation and suppression of PPARα function during fasting.

MR409, a synthetic growth hormone-releasing hormone (GHRH) analogue, has demonstrated therapeutic potential in enhancing islet cell transplantation efficacy in diabetes mice and exerts beneficial effects on cardiovascular diseases. The present study investigated the renoprotective effects of MR409 on db/db and streptozotocin (STZ)-induced diabetic mice, focusing on its role in modulating oxidative stress and ferroptosis. db/db or STZ mice combined with high fat diet were used to establish the type 2 diabetic models.

Myelin is a lipid-rich substance that is crucial for neural function. Neonatal anesthesia has been linked to neurological impairments associated with myelination dysfunction. This study sought to evaluate whether disrupted fatty acid homeostasis is involved in the mechanism of sevoflurane developmental neurotoxicity.

Background: We conducted a transcriptomic analysis to examine cerebellar transcriptional changes in a mouse model of chronic intermittent alcohol exposure.
Methods: We established a mouse model of chronic intermittent alcohol exposure and conducted a cerebellar transcriptomic analysis. After identifying differentially expressed genes, we analyzed pathway enrichment using the Kyoto Encyclopedia of Genes and Genomes and Gene Ontology.
Adrenal lipoma formation via PI(3,4,5)P/AKT-dependent transdifferentiation of adrenocortical cells into adipocytes.

Adrenal lipomas are benign tumors containing ectopic adipose tissue in the adrenal gland, an organ that normally lacks both adipocytes and their progenitors. The origin of this ectopic fat remains enigmatic, and the absence of a genetic animal model has hindered its investigation. Phosphatidylinositol 3,4,5-trisphosphate [PI(3,4,5)P], a key signaling lipid that regulates cellular growth and differentiation, is tightly regulated by the lipid phosphatases PTEN (phosphatase and tensin homolog) and SHIP2 (SH2-containing inositol phosphatase 2).
