Mineralocorticoid receptors (MR) trigger ethanol-induced vascular hypercontractility through pro-oxidative and pro-inflammatory effects. However, the contribution of MR to ethanol-induced perivascular adipose tissue (PVAT) dysfunction is unknown. Appreciating the importance of MR to PVAT dysfunction in distinctive pathological conditions, we investigated whether MR would play a role in ethanol-induced PVAT dysfunction. With this purpose, male Wistar Hannover rats were treated with ethanol 20% (in volume ratio) and/or potassium canrenoate [a MR antagonist (MRA); 30 mg/kg/day, gavage] for 5 weeks. Ethanol increased the circulating levels of aldosterone and impaired acetylcholine-induced relaxation of mesenteric arteries with, but not without PVAT. Antagonism of MR prevented ethanol-induced impairment in acetylcholine relaxation as well as the reduction of leptin levels and reactive oxygen species (ROS) overproduction in the mesenteric PVAT (mPVAT) from ethanol-treated rats. Ethanol promoted neutrophil accumulation and augmented the concentration of tumor necrosis factor (TNF)-α in the mPVAT and these responses were prevented by the MRA. Functional assays showed that tiron [a scavenger of superoxide (O<sub>2</sub><sup>•-</sup>)] and etanercept (an antibody anti-TNF-α) failed to reverse the impairment of acetylcholine-induced relaxation promoted by ethanol. In mesenteric arteries, antagonism of MR prevented ROS generation, lipoperoxidation, and increased TNF-α levels induced by ethanol. In conclusion, our findings suggest that MR is involved in ethanol-induced dysfunction of mPVAT.

The C-terminal domain is essential for the temperature activation of TREK channels, but the mechanism of temperature sensation and the nature of the temperature sensor are unknown. We studied the thermosensitivity of representatives of all K2P channel subfamilies and identified TREK-1 and TREK-2 as the only thermosensitive K2P channels, while TRAAK, the third member of the mechano-gated subfamily, showed no temperature dependence. We transferred the thermosensitivity of TREK-1 to TRAAK channels by exchanging the C-termini, demonstrating that the C-terminal domain is sufficient to confer thermosensitivity. By gradually truncating the C-terminus, we isolated a specific temperature responsive element (TRE) consisting of 18 amino acids that constitutes a unique feature in mammalian thermosensitive channels. Within this TRE lie both the binding domain for microtubule associated protein 2 (MAP2) and the PKA phosphorylation site. Pharmacological disruption of the microtubular network as well as the loss of the MAP2 binding site suppressed the temperature response, and PKA activation completely abolished temperature sensitivity. Thus, the connection to the microtubular network enables the thermosensitivity of TREK channels, which is not intrinsic to the channel itself, while the PKA-mediated phosphorylation status acts as a switch that determines if TREK channels are thermosensitive at all.</p>","PeriodicalId":19954,"journal":{"name":"Pflugers Archiv : European journal of physiology","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144079403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the remaining TAL, only about 60% of the TAL cells had strong apical ROMK staining, while 40% lacked apical ROMK but showed weak perinuclear signals. ISH revealed that apical ROMK-positive cells express Ptger3 mRNA, whereas apical ROMK-negative cells express Foxq1 mRNA. Multiplexing analysis showed that ROMK-positive cells form Claudin-10b-positive tight junctions, while ROMK-negative cells form Claudin-16/19-positive junctions and express basolateral Kir4.1.

Its involvement in various renal and pulmonary disorders makes ENaC a potential drug target. High-throughput screening using the automated patch-clamp (APC) technique appears to be a promising approach to discover novel ENaC modulators with (patho-)physiological and therapeutic implications. The aim of this methodological study was to establish APC measurements of ENaC-mediated currents. First, we confirmed functional expression of ENaC in a HEK293 cell line stably transfected with human αβγ-ENaC using conventional manual whole-cell patch-clamp recordings. For APC measurements, a standard enzymatic cell-detachment procedure was used to prepare single cell suspensions. This resulted in a high success rate of APC recordings with amiloride inhibitable ENaC currents. Using a γ-inhibitory peptide and the small molecule ENaC activator S3969, we demonstrate that APC recordings could reveal inhibitory as well as stimulatory effects on ENaC. Interestingly, the enzymatic cell-detachment protocol resulted in partial proteolytic ENaC activation. The portion of proteolytically activated channels could be reduced by prolonged incubation of suspended cells in cell culture medium. This recovery protocol enhanced the relative stimulatory effect of chymotrypsin, a prototypical serine protease known to cause proteolytic ENaC activation. Thus, this protocol may be particularly useful for identifying novel ENaC activators mimicking proteolytic channel activation. In conclusion, we have established a high-throughput screening method for the identification of novel ENaC activators and inhibitors using APC.</p>","PeriodicalId":19954,"journal":{"name":"Pflugers Archiv : European journal of physiology","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144032747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with pure shortening contractions, the SSC effect is characterised by increased force, work, and power output during the SSC shortening phase. Few studies have investigated whether SSC effects transfer across consecutive SSCs. Therefore, we investigated SSC effects over three consecutive SSCs in skinned rat muscle fibres by analysing the isometric force immediately before stretch onset (F<sub>onset</sub>), the peak force at the end of stretching (F<sub>peak</sub>), and the minimum force at the end of shortening (F<sub>min</sub>), along with mechanical (Work<sub>SSC</sub>) and shortening work (Work<sub>SHO</sub>) at different activation levels (20%, 60%, and 100%). Each SSC was followed by an isometric hold phase, allowing force to return to a steady state. Results indicated an increase in both F<sub>peak</sub> (20.3%) and Work<sub>SSC</sub> (60.9%) from SSC1 to SSC3 across all activation levels tested. At 20% and 60% activation, F<sub>onset</sub>, F<sub>min</sub>, and Work<sub>SHO</sub> increased (range: 4.5-28.5%) from SSC1 to SSC3. However, at 100% activation, F<sub>onset</sub> and Work<sub>SHO</sub> remained unchanged, while F<sub>min</sub> decreased (- 8.5%) from SSC1 to SSC3. These results suggest that the increase in SSC effects at submaximal activation may be primarily due to increased cross-bridge forces. The absence of increases in F<sub>onset</sub>, F<sub>min</sub>, and Work<sub>SHO</sub> at 100% activation suggests that increases in F<sub>peak</sub> and Work<sub>SSC</sub> may not be attributed to increased cross-bridge force but could instead be caused by additional effects, possibly involving modulation of non-cross-bridge structures, likely titin, and their stiffness.</p>","PeriodicalId":19954,"journal":{"name":"Pflugers Archiv : European journal of physiology","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144037767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the exact mechanisms connecting gut dysbiosis to these conditions are not fully understood, various lines of evidence strongly suggest a substantial role for the interaction between the gut microbiome, mitochondria, and epigenetics. Current studies suggest that the gut microbiome has the potential to affect mitochondrial function and biogenesis through the production of metabolites. A well-balanced microbiota plays a pivotal role in supporting normal mitochondrial and cellular functions by providing metabolites that are essential for mitochondrial bioenergetics and signaling pathways. Conversely, in the context of illnesses, an unbalanced microbiota can impact mitochondrial function, leading to increased aerobic glycolysis, reduced oxidative phosphorylation and fatty acid oxidation, alterations in mitochondrial membrane permeability, and heightened resistance to cellular apoptosis. Mitochondrial activity can also influence the composition and function of the gut microbiota. Because of the intricate interplay between nuclear and mitochondrial communication, the nuclear epigenome can regulate mitochondrial function, and conversely, mitochondria can produce metabolic signals that initiate epigenetic changes within the nucleus.
