Skeletal Muscle HSF1 Alleviates Age‐Associated Sarcopenia and Mitochondrial Function Decline via SIRT3‐PGC1α Axis

open access: yesAdvanced Science, EarlyView.
Aged HSF1 muscle‐specific knockout mice show deteriorated muscle atrophy and metabolic dysfunction, while active HSF1 overexpression improves muscle function via activating SIRT3 to deacetylate both PGC1α1 and PGC1α4, which boosts mitochondrial function and muscle hypertrophy in a fiber‐type specific manner, and induces FNDC5/Irisin for tissue ...

Still Heart Encodes a Structural HMT, SMYD1b, with Chaperone-Like Function during Fast Muscle Sarcomere Assembly. [PDF]

open access: yesPLoS ONE, 2015
The vertebrate sarcomere is a complex and highly organized contractile structure whose assembly and function requires the coordination of hundreds of proteins.

A Systemic Selective Modified mRNA Delivery Platform for Preventing Chemotherapy‐Induced Cardiotoxicity

open access: yesAdvanced Science, EarlyView.
In Yoo and Mainkar et al., we present a minimally invasive, CM‐selective modRNA delivery system encapsulated in lipid nanoparticles for intravenous (IV) administration. This platform enables selective cardiac translation of therapeutic modRNA but suppresses expression in off‐target tissues, including tumors.

Promoting Autophagy Mitigates Stress‐Induced Remodeling in Patient iPSC‐CMs with the Phospholamban R9C Mutation

open access: yesAdvanced Science, EarlyView.
The Phospholamban (PLN) R9C mutation reduces SERCA2a binding, increasing calcium recycling and baseline contractility. However, the excess of free PLN promotes pentamer formation, limiting phosphorylation and blunting β‐adrenergic signaling. Under cardiac stress, enhanced functional demands overwhelm proteostasis in PLN R9C cells, leading to misfolded ...

Reprogramming the Myocardial Infarction Conductive Microenvironment with Superconductive Ionic Patch for Cardiac Function Repair

open access: yesAdvanced Science, EarlyView.
A super‐conductive ionic patch reprograms the post‐infarction microenvironment by enabling stable ionic migration and electrical signal transmission within damaged myocardium. The patch rapidly adheres to cardiac tissue, enhances conduction velocity, suppresses excitation‐contraction decoupling, and promotes structural and functional cardiac repair in ...

Formin’ muscle sarcomeres [PDF]

open access: yesJournal of Cell Biology, 2012
![Figure][1] Actin filaments (magenta) show a striated pattern in wild-type body wall muscle cells (left) but are disorganized in cells lacking CYK-1 (right). Mi-Mi et al. describe two actin-nucleating proteins that assemble actin filaments into the sarcomeres of worm muscle cells ...

The Evolutionarily Conserved TPM1 Super‐Enhancer Drives Skeletal Muscle Regeneration via Mechanotransduction Signaling

open access: yesAdvanced Science, EarlyView.
By integrating biomechanical and epigenetic cues, the evolutionarily conserved TPM1 super‐enhancer drives myogenesis via TEAD4‐mediated chromatin looping. This mechanism produces species‐specific outputs (linear TPM1 mRNA in mice and CircTPM1 in bovine) that activate PI3K/AKT mechanotransduction and the MYH10/MYL3 axis to execute cytoskeletal ...

Magnetically Responsive Piezoelectric Nanocapacitors Enhance Neural Recovery Following Spinal Cord Injury via Targeted Spinal Magnetic Stimulation

open access: yesAdvanced Science, EarlyView.
This study presents a novel “in vivo–in vitro” therapeutic strategy for spinal cord injury by leveraging magnetically responsive piezoelectric nanomaterials. These nanomaterials enable targeted delivery of localized electrical stimulation at the injury site through noninvasive external magnetic actuation, thereby promoting axonal regeneration and ...

Peripheral thickening of the sarcomeres and pointed end elongation of the thin filaments are both promoted by SALS and its formin interaction partners.

open access: yesPLoS Genetics
During striated muscle development the first periodically repeated units appear in the premyofibrils, consisting of immature sarcomeres that must undergo a substantial growth both in length and width, to reach their final size.
