Sodium arsenite impairs sperm quality via downregulating the ZMYND15 and ZMYND10.

Zinc finger MYND-type containing 15 (ZMYND15) has been documented to play important roles in spermatogenesis, and mutants contribute to recessive azoospermia, severe oligozoospermia, non-obstructive azoospermia, teratozoospermia, even male infertility. ZMYND10 is involved in sperm motility. Whether environmental pollutants impair male fertility via regulating the expression of ZMYND15 and ZMYND10 has not been studied.

Sodium arsenite exposure enhances H3K14 acetylation and impairs male spermatogenesis in rat testes.

Histone modifications play important roles in the epigenetic regulation of spermatogenesis via mediating gene transcription. Steroidogenic regulatory enzymes control testosterone biosynthesis, which are essential for spermatogenesis. Arsenic exposure inhibits the expression of steroidogenic genes by significantly increasing tri-methylation of H3K9 (H3K9me3) level in rat testis, finally diminishes testosterone release and lowers the rat sperm quality.

Intergenerational differences in the urban vibrancy of TOD: Impacts of the built environment on the activities of different age groups.

Transit-oriented development (TOD) has been regarded as an effective way to improve urban vibrancy and facilitate affordable, equitable, and livable communities in metro station areas (MSAs). Previous studies placed great attention on the interplay between the MSA-level built environment and overall human activities while neglecting the heterogeneity among different age groups. To address this gap, we leverage the mobile phone signaling data to quantify the spatio-temporal distribution of the MSA-level human activities among different age groups as measured by the vibrancy index (VI).

A novel antibody-TCR (AbTCR) T-cell therapy is safe and effective against CD19-positive relapsed/refractory B-cell lymphoma.

Purpose: A barrier to widespread adoption of chimeric antigen receptor (CAR) T-cell therapy is toxicity. To address this, we recently developed a novel antibody-T-cell receptor (AbTCR) platform (trademarked as ARTEMIS) which was designed to leverage natural immune receptor signaling and regulation. The AbTCR platform includes a gamma/delta (γδ) TCR-based AbTCR construct and a separate co-stimulatory molecule, both engineered to be tumor-specific.
