The adeno-associated virus serotype 9 (AAV9)-delivered gene expression driven by the cardiac troponin T (Tnnt2) promoter is broadly considered to be cardiac-specific. However, in cases where low AAV expression is sufficient to trigger a profound biological effect in CRISPR/Cas9 gene editing, the ectopic AAV9-Tnnt2 expression and gene editing in the liver becomes non-negligible. MicroRNA122 is a microRNA that is specifically expressed in the liver.

Membrane contact sites (MCS) are specialized regions where organelles are closely interconnected through membrane structures, facilitating the transfer and exchange of ions, lipids, and other molecules. This proximity enables a synergistic regulation of cellular homeostasis and functions. The formation and maintenance of these contact sites are governed by specific proteins that bring organelle membranes into close apposition, thereby enabling functional crosstalk between cellular compartments.

After the ban on polybrominated diphenyl ethers (PBDEs), the replacement of these compounds with organophosphorus flame retardants (OPFRs) has drawn widespread attention worldwide. In arid/semi-arid regions, characteristics such as low precipitation, frequent strong winds, and low soil organic carbon content potentially influence the environmental fate of OPFRs. In this study, we investigated the concentrations of nine OPFRs in water, sediment, soil, air, and dry deposition in Lanzhou, an arid/semi-arid region in China.

Background: The genetic variants of LMNA cause an array of diseases that often affect the heart. LMNA-related cardiomyopathy exhibits high-penetrance and early-onset phenotypes that lead to late-stage heart failure or lethal arrhythmia. As a subtype of dilated cardiomyopathy and arrhythmogenic cardiomyopathy, LMNA-related cardiac dysfunction is resistant to existing cardiac therapeutic strategies, leaving a major unmet clinical need in cardiomyopathy management.

Article Synopsis
  • A coupled physical-biogeochemical model was used to study how dissolved oxygen (DO) levels change over time and space in the Bohai Sea, indicating seasonal variations with low levels in summer and high levels in winter due to ventilation.
  • The distribution of bottom DO-depleted zones is mainly influenced by water layers and the sea's topography, as well as lateral water movement, while a unique area in the Central Bank sees higher DO due to turbulence and weaker stratification.
  • Resuspension of sediments has a minimal effect (<5%) on DO levels, and the Yellow River contributes extra nutrients and phytoplankton, helping maintain a consistent, though modest, oxygen production in the region.

Mutations in genes coding sarcomere components are the major causes of human inherited cardiomyopathy. Genome editing is widely applied to genetic modification of human pluripotent stem cells (hPSCs) before hPSCs were differentiated into cardiomyocytes to model cardiomyopathy. Whether genetic mutations influence the early hPSC differentiation process or solely the terminally differentiated cardiomyocytes during cardiac pathogenesis remains challenging to distinguish.
