A Revised Perspective on the Evolution of Troponin I and Troponin T Gene Families in Vertebrates

Genome Biology and Evolution, 2022
Abstract The troponin (Tn) complex, responsible for the Ca2+ activation of striated muscle, is composed of three interacting protein subunits: TnC, TnI, and TnT, encoded by TNNC, TNNI, and TNNT genes. TNNI and TNNT are sister gene families, and in mammals the three TNNI paralogs (TNNI1, TNNI2, TNNI3), which encode proteins with tissue ...

Decreased Serum 5‐HT: Clinical Correlates and Regulatory Role in NMJ of MG

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Although 5‐Hydroxytryptamine (5‐HT) indirectly stimulates muscle contraction and participates in regulating Acetylcholine receptor (AChR) cluster homeostasis in cellular, animal, and clinical studies, evidence regarding its potential to modulate muscle contraction in myasthenia gravis (MG) remains limited.

Characterization of a Cardiac Troponin C-Troponin I Chimera Protein [PDF]

Biophysical Journal, 2013
Association of the regulatory N-domain of cardiac troponin C (cNTnC) with the switch region of cardiac troponin I (cTnI147-163) is a major step in Ca2+ regulation of myocardial contraction by troponin as it triggers a series of downstream events that leads to contraction.

Proximity mapping of troponin T and troponin I in cardiac troponin using molecular dynamics simulations [PDF]

Biophysical Journal, 2009
The intersite distances from cTnT residues 240, 276, and 288 to cTnI N-terminal residues 5, 17, 27, 40, and to the cTnI C-terminal residues 131, 145, 152, 160, and 167 in reconstituted cTn were determined in the presence of Mg2+ and Mg2+ plus Ca2+ using FRET.

Tapered Pillar Design for High‐Precision Force Readout in Miniaturized Engineered Heart Tissues From Human Pluripotent Stem Cells

Advanced Healthcare Materials, EarlyView.
Engineered heart tissues (EHTs) are a valuable approach in capturing human cardiac physiology and drug responses in vitro. Here, a novel tapered pillar design is developed in an EHT platform to confine tissues in a predefined position‐ at the middle of the pillar height.

Robust pH Sensing Using a Graphene Oxide and Covalent Organic Frameworks Composite for Gastro‐esophageal Reflux Disease Diagnosis

Advanced Healthcare Materials, EarlyView.
A stable composite pH sensor is developed by coating graphene oxide (GO) nanosheets with covalent organic frameworks (COFs) to improve stability and sensitivity in acidic environments. The GO/COFs sensor demonstrates high selectivity, linearity, and biocompatibility, offering a promising strategy for continuous pH monitoring in gastro‐esophageal reflux
