As the most common mutation in papillary thyroid cancer (PTC), B-type Raf kinase V600E mutation ( ) has become an important target for the clinical treatment of PTC. However, the clinical application still faces the problem of resistance to BRAF inhibitors (BRAFi). Therefore, exploring BRAF-associated prognostic factors to providing potential joint targets is important for combined targeted therapy with BRAFi.

The foremost among these is the threat posed by oxidative stress, which arises from an imbalance in reactive oxygen species and can elicit damage to cellular lipids, proteins, and nucleic acids. In mice, the risk of oxidative damage to spermatozoa is mitigated through the expression and secretion of glutathione peroxidase 5 (GPX5) as a major luminal scavenger in the proximal caput epididymidal segment.

Renal tubule cells can recover after they undergo AKI (acute kidney injury). An incomplete repair of renal tubules can result in progressive fibrotic CKD (chronic kidney disease). Studies have revealed the relationship between tubular epithelial cells and kidney fibrogenesis.

The purpose of this study was to construct a conditional murine polyomavirus middle T antigen gene (PyMT) transgenic mice model, in order to provide a basis for the treatment of vascular anomalies in vivo, as well as the study of PyMT's molecular function. A new conditional transgenic vector based on Tet-On system was constructed successfully.

Objective: To construct the doxycycline-inducible MT transgenic mice model, and provide a basis for the study of hemangioma as well as MT molecular function in vivo.
Methods: Tetracycline-controlled expression systems were employed to this study. A conditional transgenic vector combining the two transcriptional units on a single plasmid was constructed, and the MT gene was subcloned into this vector.
