- Mitochondrial calcium homeostasis involves coordinated uptake via the mitochondrial calcium uniporter (MCU) and efflux through sodium-dependent NCLX (encoded by SLC8B1) and/or TMEM65. We investigated TMBIM5, a proposed bidirectional mitochondrial calcium/proton transporter, by generating zebrafish lacking tmbim5, slc8b1, plus tmbim5/mcu and tmbim5/slc8b1 double knockouts. Tmbim5-deficient fish exhibited growth impairment, muscle atrophy, and increased brain cell death. tmbim5/mcu double knockouts showed no additive effects, arguing against Tmbim5 functioning as an independent calcium uptake pathway. slc8b1 knockouts had no major phenotype but showed attenuated, although not abolished sodium-dependent mitochondrial calcium efflux. tmbim5/slc8b1 double knockouts showed altered mitochondrial calcium handling with reduced uptake and efflux. Remarkably, brain phenotypes were rescued while muscle dysfunction was exacerbated in double mutants, corresponding to restored mitochondrial membrane potential in brain tissue and decreased calcium levels in muscle. These findings suggest that TMBIM5 functions as an auxiliary calcium efflux pathway cooperating with NCLX in a tissue-specific manner. - Source: PubMed

Wasilewska IgaMajewski ŁukaszAdamek-Urbańska DobrochnaBaranykova SofiiaCastañeda-Tamez PaulinaWittig IlkaMacias MatyldaSzybińska AleksandraMethner Axel - As a key mitochondrial Ca transporter, NCLX regulates intracellular Ca signalling and vital mitochondrial processes. The importance of NCLX in cardiac and nervous-system physiology is reflected by acute heart failure and neurodegenerative disorders caused by its malfunction. Despite substantial advances in the field, the transport mechanisms of NCLX remain unclear. Here we report the cryo-electron microscopy structures of NCLX, revealing its architecture, assembly, major conformational states and a previously undescribed mechanism for alternating access. Functional analyses further reveal an unexpected transport function of NCLX as a H/Ca exchanger, rather than as a Na/Ca exchanger as widely believed. These findings provide critical insights into mitochondrial Ca homeostasis and signalling, offering clues for developing therapies to treat diseases related to abnormal mitochondrial Ca. - Source: PubMed

We conducted GWASs on various semen traits of Duroc boars, including MOT, DEN, ABN, MMP, AIR, and ROS levels. These traits were assessed using FCM and CASA. A total of 1183 Duroc boars were genotyped using the GeneSeek GGP Porcine 50 K SNP BeadChip. The GWAS was performed using three different models: GLM, MLM, and FarmCPU. Additionally, trait heritability was estimated using single- and multiple-trait PBLUP models, yielding 0.19, 0.29, 0.13, 0.18, 0.11, and 0.14 heritability for MOT, DEN, ABN, MMP, AIR, and ROS, respectively. All semen traits exhibited low heritability except ABN, which demonstrated medium heritability. Nine candidate genes (, , , , , , , , and ) were potentially associated with semen traits. These genes are associated with antioxidant and mitochondrial functions in porcine sperm. Our findings provide insight into the genetic architecture of semen traits in Duroc boars, and the identified SNPs and candidate genes may enhance economic outcomes in the pig breeding industry while improving sperm quality through targeted breeding strategies. - Source: PubMed

Yang XiyanNie JingkunZhang YaxuanWang SuqingZhu XiaopingLi ZhiliZhao YunxiangShang Xiuguo - Eukaryotic cells and organisms depend on oxygen for basic living functions, and they display a panoply of adaptations to situations in which oxygen availability is diminished (hypoxia). A number of these responses in animals are mediated by changes in gene expression programs directed by hypoxia-inducible factors (HIFs), whose main mechanism of stabilization and functional activation in response to decreased cytosolic oxygen concentration was elucidated two decades ago. Human acute responses to hypoxia have been known for decades, although their precise molecular mechanism for oxygen sensing is not fully understood. It is already known that a redox component, linked with reactive oxygen species (ROS) production of mitochondrial origin, is implied in these responses. We have recently described a mechanism by which the mitochondrial sodium/calcium exchanger, NCLX, participates in mitochondrial electron transport chain regulation and ROS production in response to acute hypoxia. Here we show that NCLX is also implied in the response to hypoxia mediated by the HIFs. By using a NCLX inhibitor and interference RNA we show that NCLX activity is necessary for HIF-α subunits stabilization in hypoxia and for HIF-1-dependent transcriptional activity. We also show that hypoxic mitochondrial ROS production is not required for HIF-1α stabilization under all circumstances, suggesting that the basal cytosolic redox state or other mechanism(s) could be operating in the NCLX-mediated response to hypoxia that operates through HIF-α stabilization. This finding provides a link between acute and medium-term responses to hypoxia, reinforcing a central role of mitochondrial cell signalling in the response to hypoxia. - Source: PubMed

However, the construction of prognostic models using calcium extrusion-related genes in colon adenocarcinoma (COAD) has not been well studied. We aimed to identify whether calcium extrusion-related genes serve as a potential prognostic biomarker in the COAD progression. - Source: PubMed
