Figure Lengend Snippet: MiR-136-3p content in cell culture medium and uptake of extracellular miR-136-3p into cultured myotubes. MiRNA content in (A) human myotubes and (B) human pancreatic islets culture media. Results were first normalized using RNU1A1 and then presented in relation to miR-23a-3p content for n = 4 different donors for myotubes cultures and n = 4 donors for human islets. Left panel (C) shows bright-field image of cultured human myotubes and right panel (C) shows a representative fluorescence image of cultured human myotubes with cells exposed to human serum-derived EVs loaded with Cy3-miR-136-3p. Cy3 fluorescence (red) is detected in the whole cytoplasm of the human myotubes. (D) Representative fluorescence image of human myotubes exposed to HEK293 culture medium with EVs loaded with Cy3-miR-136-3p (red). (E) Representative image of human myotubes exposed to EVs loaded with TexasRed-labeled with a control RNA (orange). Nuclear Hoechst staining is shown in blue. Scale bar = 100 μm. EVs = extracellular vesicles; HEK293 = human embryonic kidney; miR = microRNA; Rel = relative; RNU1A1 = U1 small nuclear RNA.

Article Title: Exercise training-induced extracellular miR-136-3p modulates glucose uptake and myogenesis through targeting of NRDC in human skeletal muscle

doi: 10.1016/j.jshs.2025.101091

Figure Lengend Snippet: NRDC is a direct target of miR-136-3p in human myotubes. Skeletal muscle NRDC mRNA is responsive to training and inactivity. (A) Tissue mRNA expression of NRDC from the Human Protein Atlas database showing enriched expression of NRDC in human skeletal muscle. (B) The miR-136-3p target site in the NRDC gene is highly conserved in mammals. (C) Luciferase activity in HEK293 cells co-transfected the NRDC 3’UTR and miR-136-3p with or without anti-miR136-3p inhibitors. miR-136-3p transfection downregulates NRDC (D) mRNA and (E) representative image of protein abundance in human myotubes. (F) Publicly available data ( GSE14413 ) showing NRDC mRNA expression in human skeletal muscle of healthy young participants after 6 weeks of endurance training ( n = 8). (G) Publicly available data ( GSE120862 ) showing NRDC mRNA expression in human skeletal muscle of healthy young participants after 2 months of aerobic training ( n = 10). (H) Publicly available data ( GSE14901 ) showing NRDC mRNA expression in human skeletal muscle of healthy young participants after 14 days of immobilization ( n = 24). * p < 0.05, ** p < 0.005. GSE = gene set enrichment; HEK293 = human embryonic kidney; miR = microRNA; NC = negative control; NRDC = nardilysin convertase; nTPM = normalized transcripts per million; si NRDC = small interfering RNA of NRDC ; UTR = untranslated region.

Article Title: The MYB-related transcription factor MYPOP acts as a selective regulator of cancer cell growth

doi: 10.1038/s42003-026-10272-2

Figure Lengend Snippet: a Endogenous protein levels of MYPOP in untreated cancer cell lines. Normal skin cells (NHEK) and normal lung cells (181576 N, 181652 N) served as controls. GAPDH or β-actin staining was used as loading control. b Cancer cells were transfected with either a MYPOP expression plasmid or a control plasmid, selected for 6–12 days with G418, fixed, and stained with crystal violet. The cell-covered area was quantified (relative area). Values are presented as mean + SD. The mean for control-transfected cells was set to 100% (dotted line). Statistical significance was determined by comparing control and MYPOP expressing cells with p = 0.0022 for Huh7 ( n = 3), p = 0.0028 for HEK293 ( n = 5), p = 0.0064 for MCF7 ( n = 4), p = 0.0294 for HCT116 ( n = 3), p = 0.0106 for HeLa ( n = 3), p = 0.0003 for A549 ( n = 3), and p = 0.0026 for 2106 T ( n = 4).
