Parvalbumin affects skeletal muscle trophism through modulation of mitochondrial calcium uptake

Cell Reports, 2021
Summary: Parvalbumin (PV) is a cytosolic Ca2+-binding protein highly expressed in fast skeletal muscle, contributing to an increased relaxation rate. Moreover, PV is an “atrogene” downregulated in most muscle atrophy conditions.

Rag GTPases are cardioprotective by regulating lysosomal function. [PDF]

, 2014
The Rag family proteins are Ras-like small GTPases that have a critical role in amino-acid-stimulated mTORC1 activation by recruiting mTORC1 to lysosome.

4D Bioprinted Self‐Folding Scaffolds Enhance Cartilage Formation in the Engineering of Trachea

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A bilayer self‐folding scaffold, triggerable by humidity, is fabricated via 4D bioprinting for trachea engineering. An analytical model is derived to predict its radius of curvature, enabling its scalability. Cartilage progenitor cells seeded on the scaffold perceive scaffold final curvature and react to it, by enhancing the upregulation of pro ...

Sarcoplasmic Hypertrophy in Skeletal Muscle: A Scientific “Unicorn” or Resistance Training Adaptation?

Frontiers in Physiology, 2020
Skeletal muscle fibers are multinucleated cells that contain mostly myofibrils suspended in an aqueous media termed the sarcoplasm. Select evidence suggests sarcoplasmic hypertrophy, or a disproportionate expansion of the sarcoplasm relative to myofibril

CRISPR‐MI and scRNA‐Seq Reveal TREM2's Function in Monocyte Infiltration and Macrophage Apoptosis During Abdominal Aortic Aneurysm Development

Advanced Science, EarlyView.
A method is developed for conducting genome‐wide CRISPR/Cas9 screening of monocyte infiltration in vivo (CRISPR‐MI) that is easily adaptable across a variety of disease models. Through the combination of CRISPR‐MI and scRNA‐Seq, this study discovers that Trem2 is a key regulator of early monocyte infiltration in abdominal aortic aneurysm (AAA ...

PRDM16 Reduces Cellular Senescence by Upregulating GSTM1

Advanced Science, EarlyView.
Cellular senescence drives aging and aging‐related organ disorders, yet PRDM16's role remains unexplored. This work uncovers that PRDM16 decreases significantly in aged organs, while its loss accelerates cellular senescence and aging‐related organ injury.

Cell-based gene therapy for mending infarcted hearts [PDF]

, 2011
The goal of this study was to analyse the efficiency of a combinatorial cell/growth factor therapy to improve function of infarcted murine hearts. The Insulin-like Growth Factor-1 (IGF-1) isoform, IGF-1Ea, has been shown to reduce scar formation and ...

Life Factors and Melanoma: From the Macroscopic State to the Molecular Mechanism

Advanced Science, EarlyView.
Melanoma, an aggressive skin cancer, arises from dynamic interactions between genetic, environmental, and lifestyle factors. This review explores how age, gender, obesity, diet, exercise, smoking, alcohol, UV exposure, circadian rhythms, and medications influence melanoma risk and progression.

Myonuclear Domain Flexibility Challenges Rigid Assumptions on Satellite Cell Contribution to Skeletal Muscle Fiber Hypertrophy

Frontiers in Physiology, 2018
Satellite cell-mediated myonuclear accretion is thought to be required for skeletal muscle fiber hypertrophy, and even drive hypertrophy by preceding growth. Recent studies in humans and rodents provide evidence that challenge this axiom.
