Mesothelin-targeted CAR-NK Cells Derived From Induced Pluripotent Stem Cells Have a High Efficacy in Killing Triple-negative Breast Cancer Cells as Shown in Several Preclinical Models.

The emergence of immunotherapy has introduced a promising, novel approach to cancer treatment. While multiple chimeric antigen receptor (CAR) T-cell therapies have demonstrated remarkable clinical efficacy against leukemia, their effect on solid tumors has been limited. One potential option for treating solid tumors is the engineering of natural killer (NK) cells with CARs.

[Effect of intra-testicular testosterone withdrawal on the expression of alpha-catenin in the adult rat testis].

Objective: To study the expression of alpha-catenin in the rat testis after intra-testicular testosterone withdrawal induced by injection of testosterone undecanoate (TU).

Methods: Ten adult male SD rats received vehicle (n = 5 ) or TU (19 mg/kg every 15 days, n = 5) for 130 days. Paraffin-embedded testicular sections were used for immunohistochemistry against a polyclonal anti-alpha-catenin antibody.

Molecular phylogeny of Sinocyclocheilus (Cypriniformes: Cyprinidae) inferred from mitochondrial DNA sequences.

More than 10 species within the freshwater fish genus Sinoncyclocheilus adapt to caves and show different degrees of degeneration of eyes and pigmentation. Therefore, this genus can be useful for studying evolutionary developmental mechanisms, role of natural selection and adaptation in cave animals. To better understand these processes, it is indispensable to have background knowledge about phylogenetic relationships of surface and cave species within this genus.
