In animals, muscle growth is a quantitative trait controlled by multiple genes. Previously, we showed that the transient receptor potential channel 1 () gene was differentially expressed in muscle tissues between pig breeds with divergent growth traits base on RNA-seq. Here, we characterized expression profiles in different tissues and pig breeds and showed that was highly expressed in the muscle. We found two single nucleotide polymorphisms (SNPs) (C-1763T and C-1604T) in that could affect the promoter region activity and regulate pig growth rate. Functionally, we used RNAi and overexpression to illustrate that promotes myoblast proliferation, migration, differentiation, fusion, and muscle hypertrophy while inhibiting muscle degradation. These processes may be mediated by the activation of Wnt signaling pathways. Altogether, our results revealed that might promote muscle growth and development and plays a key role in Wnt-mediated myogenesis.

Lymphangioleiomyomatosis (LAM) is a rare lung disease caused by hyperactivation of the mechanistic/mammalian target of rapamycin 1 (mTORC1) growth pathway in a subset of mesenchymal lung cells. Histopathologically, LAM lesions have been described as immature smooth muscle-like cells positive for the immature melanocytic marker HMB45/PMEL/gp100 and phosphorylated ribosomal protein S6 (pS6). Advances in single cell sequencing (scRNA-seq) technology allowed us to group LAM cells according to their expression of cancer stem cell (CSC) genes and identify three clusters: a high CSC-like state (SLS), an intermediate state, and a low CSC-like inflammatory state (IS).

» Early-onset scoliosis (EOS) causes restrictive lung disease, secondary to deformation of the thoracic cavity, stiffening of the chest wall, and weakening of the respiratory muscles.» Early spinal fusion has been shown to limit thoracic growth and be associated with poor pulmonary outcomes. This has led to the rise of growth-friendly surgical techniques to maximize thoracic growth.

In adult mammals and other highly developed animals, incomplete wound healing, scar formation, and fibrosis occur. No treatment for complete tissue regeneration is currently available. However, in mice, at up to 13 days of gestation, early embryonic wounds regenerate without visible scarring.

Loss of actin cytoskeleton control can hinder integral developmental and physiological processes and can be the basis for a subset of developmental defects. SHROOM3 is an actin binding protein, best characterized as being essential for neural tube closure in vertebrates. Shroom3 expression has also been identified in the developing heart, with some associated congenital heart defects.

Non-small cell lung cancer (NSCLC) continues to be the number one cause of cancer-related death for both women and men worldwide. More information needs to be gathered to understand the interactions between cancer cells, the immune system, the microenvironment within each tumor, and the host tissue to develop more effective treatment modalities. Reported here is a simple, repeatable method for inducing cancer within the mouse lung, allowing for the monitoring of tumor growth from early to late-stage disease.
