(Submitter supplied) We identify two quiescent stem-cell states through relative CD34 expression: CD34High, with stemness properties (genuine state), and CD34Low, more committed to myogenic differentiation (primed state). The genuine-quiescent state is preserved into later life succumbing only in extreme old age due to acquisition of primed-state traits. We identified niche-derived IGF1-dependent Akt activation as detrimental to the genuine stem-cell state by imposing primed-state features via FoxO inhibition. more...

(Submitter supplied) Insulin deficiency and uncontrolled diabetes lead to a catabolic state with decreased muscle strength, contributing to disease-related morbidity. FoxO transcription factors are suppressed by insulin and thus are key mediators of insulin action. To study their role in diabetic muscle wasting, we created mice with muscle-specific triple knockout of FoxO1/3/4 and induced diabetes in these M-FoxO-TKO mice with streptozotocin (STZ). more...

(Submitter supplied) Forkhead box class O (FoxO) transcription factors regulate whole body energy metabolism, skeletal muscle mass and substrate switching. To elucidate the role of FOXO in skeletal muscle, dominant negative (dn) constructs for FOXO1 (FOXO1dn) or FOXO3 (FOXO3dn) were transfected by electroporation into mouse tibialis anterior muscle and glucose uptake, signal transduction, and glucose stimulated gene expression profiles were assessed. more...

(Submitter supplied) We report that whole body PRMT7-/- adult mice display a significant reduction in in muscle mass. RNA sequencing was performed to identify potential PRMT7 targets. We found that top canonical pathways affected by the loss of PRMT7 includes cell cycle and senescence.

(Submitter supplied) Muscle stem cells (MuSC) change molecular and functional properties during development. Using a transgenic Tg:Pax7-nGFP mice, we FACS-isolated MuSC from embryonic (E12.5) and foetal (E17.5) stages to understand the differences and similarities amongst the myogenic stem/progenitor populations.

(Submitter supplied) Notch signalling plays crucial roles in mediating cell fate choices in all metazoans largely by specifying the transcriptional output of one cell in response to a neighbouring cell. The DNA-binding protein RBPJ is the principle effector of this pathway in mammals and together with the transcription factor moiety of Notch (NICD) it regulates the expression of target genes. The prevalent view presumes that RBPJ statically occupies consensus binding sites while exchanging repressors for activators in response to NICD. more...

(Submitter supplied) We identify sestrins, a family of stress-inducible metabolic regulators, as protective factors against muscle wasting. Sestrin expression decreases during inactivity and its genetic deficiency exacerbates muscle wasting; conversely, sestrin overexpression suffices to prevent atrophy.

(Submitter supplied) Sustainable muscle regeneration necessitates proper maintenance of the quiescence-reversible SCs pool. Activation of p16Ink4a-associated senescence pathway during aging breaks muscle homeostasis and causes degenerative muscle disease by irreversibly dampening satellite cell (SC) self-renewal capacity. We performed microarrays analysis to compare the genome-wide gene expression profiles of wild-type and Slug-deficient SCs and identified distinct classes of up-regulated genes upon deletion of Slug gene.

(Submitter supplied) (Abstract of publication submitted currently) To clarify molecular regulation of satellite cells, we performed genome-wide gene expression analysis of quiescent satellite cells isolated from mouse skeletal muscle by flow cytometry. We identified 53 novel quiescent satellite cell-specific genes whose expressions are sharply down-regulated upon activation. The gene list contains a number of cell surface molecules, transcriptional factors, and cytokines and other signal transduction molecules. more...

(Submitter supplied) Skeletal muscle possesses remarkable regenerative potential due to satellite cells, a stem cell population located beneath the muscle basal lamina. By lineage tracing of progenitor cells expressing the Twist2 (Tw2) transcription factor in mice, we discovered a unique myogenic lineage that resides outside the basal lamina of adult muscle and contributes specifically to type IIb/x myofibers during adulthood and muscle regeneration. more...

(Submitter supplied) Regeneration of skeletal muscle depends on a population of adult stem cells (satellite cells) that remain quiescent throughout life. Satellite cell regenerative functions decline with aging and in progeric conditions. Here we show that geriatric satellite cells, compared to old cells, are incapable of maintaining their normal quiescent state in muscle homeostatic conditions, and this irreversibly affects their intrinsic regenerative and self-renewal capacities.
