Cancer-derived extracellular succinate: a driver of cancer metastasis

Journal of Biomedical Science, 2022
Succinate is a tricarboxylic acid (TCA) cycle intermediate normally confined to the mitochondrial matrix. It is a substrate of succinate dehydrogenase (SDH). Mutation of SDH subunits (SDHD and SDHB) in hereditary tumors such as paraganglioma or reduction

XIAP Deficiency Impairs Colonic Tuft Cell Development and Predisposes to Crohn's Disease

MedComm, Volume 7, Issue 5, May 2026.
XIAP deficiency leads to impaired colonic tuft cells development and JAK–‐STAT pathway hyperactivation in CD patients and mice. Mechanically, XIAP regulates tuft cells development through Wnt–‐TLE4/TCF–‐ASCL2 signaling. Tuft cells deficiency predisposes XIAP‑‐deficient CD patients or Xiap−/−‐/‐ mice to hazardous microbial effects, driving colonic ...

Data on the mechanisms underlying succinate-induced aortic contraction

Data in Brief, 2016
We describe the mechanisms underlying the vascular contraction induced by succinate. The data presented here are related to the article entitled “Pharmacological characterization of the mechanisms underlying the vascular effects of succinate” (L.N. Leite,

Targeting Tumor Stroma: Current Challenges and Future Directions

MedComm, Volume 7, Issue 5, May 2026.
Figure 1. Mechanism of ECM reprogramming. Cancer‐associated fibroblasts (CAFs), cancer‐associated macrophages (CAMs), and other mesenchymal cells alter the ECM composition and increase its stiffness by depositing matrix components such as collagen and hyaluronic acid, and secreting cross‐linking agents like lysyl oxidase homolog 2 (LOXL2).

MITOCHONDRIA-CONTROLLED SIGNALING MECHANISMS OF BRAIN PROTECTION IN HYPOXIA

Frontiers in Neuroscience, 2015
The article is focused on the role of the cell bioenergetic apparatus, mitochondria, involved in development of immediate and delayed molecular mechanisms for adaptation to hypoxic stress in brain cortex.

Aging‐Driven Immunosuppression: The Role of Tregs in the Ovarian Tumor Microenvironment

Aging Cell, Volume 25, Issue 5, May 2026.
In the aged ovarian TME, cancer cells exhibit increased succinate production. Elevated extracellular succinate activates the SUCNR1 receptor on Tregs, promoting their recruitment and contributing to an immunosuppressive environment. This leads to diminished anti‐tumor T cell responses and reduced survival.

Transcription factors regulate GPR91-mediated expression of VEGF in hypoxia-induced retinopathy [PDF]

Scientific Reports, 2017
AbstractHypoxia is the most important factor in the pathogenesis of diabetic retinopathy (DR). Our previous studies demonstrated that G protein-coupled receptor 91(GPR91) participated in the regulation of vascular endothelial growth factor (VEGF) secretion in DR.

Dietary anthocyanidin pelargonidin activates G protein‐coupled receptor 35

The FEBS Journal, Volume 293, Issue 5, Page 1386-1399, March 2026.
Pelargonidin, a red‐fruit‐derived anthocyanidin, was newly identified as a dietary agonist of GPR35, a metabolite‐sensing GPCR implicated in anti‐inflammation. Through screening of dietary compounds, pelargonidin emerged as a potent GPR35 agonist, attenuating inflammation in human intestinal cells.

Deficiency in the metabolite receptor SUCNR1 (GPR91) leads to outer retinal lesions

Aging, 2013
Age-related macular degeneration (AMD) is a prominent cause of blindness in the Western world. To date, its molecular pathogenesis as well as the sequence of events leading to retinal degeneration remain largely ill-defined. While the invasion of choroidal neovessels in the retina is the primary mechanism that precipitates loss of sight, an earlier dry

Gut microbiota and central nervous system's direct bidirectional regulation: The mechanisms of the gut–brain axis in irritable bowel syndrome

Clinical and Translational Discovery, Volume 6, Issue 1, February 2026.
Gut microbiota directly modulates central nervous system activity via vagal, sympathetic and sensory neural circuits. Brainstem nuclei integrate microbial signals to regulate gut motility, secretion and visceral sensitivity. DRG neurons and stress‐responsive pathways link microbial cues to host defence and epithelial homeostasis. Dysregulated gut–brain
