Recently, macrophage metabolism has been recognized as attractive targets to develop novel immunomodulatory therapy for sepsis research. However, the fine-tuning regulators dictating macrophage functions and the specific mechanisms underlying macrophage metabolic reprogramming remain largely obscure. Sphingosine-1-phosphate (S1P), a metabolic mediator of sphingolipid catabolism, predominantly formed through sphingosine kinase 1 (SphK1) catalyzing, mediates inflammation in sepsis by binding to S1P receptor 3 (S1PR3) expressed in macrophages. Here we demonstrate that SphK1/S1PR3 axis was upregulated in lipopolysaccharide (LPS)-induced macrophages and septic mice lungs, cascading the activation of proglycolytic signaling such as HIF-1α, HK2 and PFKFB3. Targeted inhibition of Sphk1 by PF-543 effectively abrogated upregulated SphK1/S1PR3 axis in vitro and in vivo. In addition, PF-543 significantly suppressed sepsis-related inflammation and multi-organ injury in vivo. Furthermore, PF-543 not only blunted key glycolytic enzymes HIF-1α, HK2, and PFKFB3 in LPS-treated macrophages but also inhibited HK2 and PFKFB3 in septic mice. Silencing or inhibiting SphK1 tempered pro-inflammatory M1 macrophages while boosted anti-inflammatory M2 macrophages. Intriguingly, S1PR3 knockdown proficiently dampened glycolysis-associated markers, retrieved LPS-modulated M1/M2 polarization and attenuated NF-κB p65 activation. In conclusion, our study provides the first evidence that PF-543 orchestrates proportional imbalance of macrophage polarization and the Warburg effect in a SphK1/S1PR3 dependent manner during sepsis, mitigating both hyperinflammation and multi-organ failure, adding a novel puzzle piece to pharmacologically exploitable therapy for sepsis.</p>","PeriodicalId":8754,"journal":{"name":"Biochimica et biophysica acta.

Here we describe the consequences of inducing type 3 diabetes by feeding <em>Drosophila</em> on a high sucrose diet, which effectively mimics the pathophysiology of diabetes. A high sucrose diet increases glycogen and lipid accumulation.

The results showed that creating diabetic conditions by using insulin receptor (InR) knockdown in the eyes of <em>Drosophila</em> led to a degenerative phenotype, indicating a genetic interaction between the insulin signaling pathway and Alzheimer's disease. The expression of PERK reflects disruption in the endoplasmic reticulum homeostasis due to amyloid-β (Aβ) under a high sucrose diet.

Oncogenic mutations in KRAS are considered the most common gain-of-function mutations, affecting 30–50 % of colorectal cancer (CRC) patients. While RAS proteins usually play an anti-apoptotic role, little is known about the involvement of KRAS mutations in apoptosis regulation. Here, we aimed to elucidate the role of mutated human KRAS in the regulation of BAX, a key pro-apoptotic member of the Bcl-2 family. For this purpose, we took advantage of the simpler yeast model <em>Saccharomyces cerevisiae</em>, using cells deficient in the main yeast RAS isoform (<em>ras2</em>Δ) co-expressing wild-type KRAS (KRAS^WT) or the most frequent KRAS mutations found in CRC - KRAS^G12D, KRAS^G12V or KRAS^G13D, along with human BAX. We show that, in comparison with KRAS^WT, KRAS mutants confer resistance to BAX-induced death and cytochrome <em>c</em> (cyt <em>c</em>) release. The modulation of BAX by KRAS isoforms seems to result from a direct interaction between these proteins, as they co-localize at the mitochondria and there is evidence they may physically interact. We further show that acetic acid significantly increased cell death in cells expressing BAX and co-expressing oncogenic KRAS mutants, but not KRAS^WT. This suggests a potential mechanism explaining the increased sensitivity of CRC cells harboring a KRAS-activated pathway to acetate. These findings contribute to a clearer understanding of how KRAS regulate BAX function, a relevant aspect in tumor progression.</div></div>","PeriodicalId":8754,"journal":{"name":"Biochimica et biophysica acta.

To this end, the tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is a promising anticancer strategy. Some CRC cell lines such as SW620 have low sensitivity to TRAIL, so additional sensitizers are required to make the strategy effective. Therefore, we focused on the apoptotic effect of combinational metformin and TRAIL treatment on TRAIL-resistant SW620 cells. Treatment with TRAIL alone did not induce apoptosis whereas combined treatment with metformin and TRAIL significantly increased it. TRAIL activated caspases through an extrinsic pathway but increased resistance to apoptosis through the protein kinase B or AKT (PKB/AKT)/mammalian target of rapamycin (mTOR) pathway. On the other hand, metformin reduced the inhibitory effect of X-linked inhibitor of apoptosis (XIAP) by blocking the AKT and nuclear factor kappa B (NF-κB) pathways and activated CCAAT-enhancer-binding protein homologous protein (CHOP) via endoplasmic reticulum (ER) stress but without inducing apoptosis. In addition, metformin induced cell-cycle arrest, thereby blocking cell proliferation and growth. These results were also confirmed through an in vivo mouse xenograft CRC model, in which combined treatment with metformin and TRAIL induced tumor cell death, thus demonstrating the anticancer effect of their coadministration. Therefore, cotreatment of metformin and TRAIL could be an effective anticancer treatment strategy for TRAIL-resistant CRC.</div></div>","PeriodicalId":8754,"journal":{"name":"Biochimica et biophysica acta.

These proteins feature a conserved AAA+ domain essential for ATPase activity and a hexameric assembly. This review provides an in-depth analysis of the evolution and functional divergence of the FIGN family members, highlighting their role in the dynamic organization of the cytoskeleton. We further explore their broader biological functions across various species, systems, and subcellular localization. Although the FIGN family is conserved, each member exhibits unique structural characteristics and functions that reflect their evolutionary adaptations. FIGNL1 is found across animal species, while FIGNL2 is specific to vertebrates, thereby indicating its more recent evolutionary origin. Moreover, synteny analysis has revealed that FIGN is located in a more conserved genomic region compared to FIGNL2, which has undergone substantial evolutionary changes. The expression patterns of the FIGN members also vary across organisms and tissues. For example, FIGNL2 shows a notably reduced expression in the mammalian nervous system compared to that in lower vertebrates. The FIGN family members have distinct roles in microtubule severing, cell division, and DNA repair. Specifically, FIGN is involved in cell division and neuronal regeneration, FIGNL1 in axonal growth and DNA repair, and FIGNL2 in cell migration and vascular development. Their involvement in these processes underscores their role as potential biomarkers for certain cancers as well as therapeutic targets for diseases affecting the nervous system and cardiovascular development. All these evolutionary insights and functional distinctions of the FIGN family offer a comprehensive framework for understanding cytoskeletal regulation and its implications in health and disease.</div></div>","PeriodicalId":8754,"journal":{"name":"Biochimica et biophysica acta.
