Imeglimin attenuates liver fibrosis by inhibiting vesicular ATP release from hepatic stellate cells

open access: yesFEBS Letters, EarlyView.
Imeglimin, at clinically relevant concentrations, inhibits vesicular ATP accumulation and release from hepatic stellate cells, thereby attenuating purinergic signaling and reducing fibrogenic activation. This mechanism reveals a newly identified antifibrotic action of imeglimin beyond glycemic control.

Cancer cell death induced by the NAD antimetabolite Vacor discloses the antitumor potential of SARM1

open access: yesFEBS Letters, EarlyView.
Vacor, a compound converted into the toxic metabolite Vacor adenine dinucleotide (VAD) by the nicotinamide salvage pathway enzymes NAMPT and NMNAT2, exhibits antitumor activity by inducing rapid and complete NAD depletion. We report that Vacor toxicity is limited to cell lines expressing high levels of SARM1, a NAD glycohydrolase.

Protein kinase FAM20C—when subcellular localization matters

open access: yesFEBS Letters, EarlyView.
FAM20C is a Golgi‐resident kinase that phosphorylates proteins along the entire secretory pathway. The presence of potential FAM20C substrates in the cytoplasm or nucleus raises the question of how the kinase and its substrates encounter each other. Protein kinases achieve signaling specificity through consensus sequence recognition and subcellular ...

A Latent Multi-Scale Residual Transformer Approach for Cross-Modal Medical Image Synthesis

open access: yesIEEE Access
Cross-modal generation has emerged as a crucial method for addressing the challenge of filling in missing modalities in medical imaging. Existing approaches predominantly utilize convolutional neural networks (CNNs) or vision transformers (ViTs) and ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Superior Mesenteric Artery First Approach versus Conventional Pancreaticoduodenectomy in Periampullary Adenocarcinomas: A Single Institutional Observational Study

open access: yesJournal of Clinical and Diagnostic Research
Introduction: Periampullary malignancies represent a group of malignancies at and around the ampulla of Vater, whose clinical features and management are similar, with Pancreaticoduodenectomy (PD, Whipple procedure) being the standard surgical treatment.

RAD50 missense variants differentially affect the DNA damage response and mitotic progression

open access: yesFEBS Letters, EarlyView.
RAD50 incorporates into the MRN complex and initiates the DNA damage response. Furthermore, RAD50 promotes mitotic progression. RAD50 missense variants capable of forming an MRN complex supported the DNA damage response and mitotic features to different extents in complementation experiments, indicating these functions are separable and might impact ...

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
