Connexin43 Deficiency Leads to Ventricular Arrhythmias by Reprogramming Proline Metabolism

Advanced Science, EarlyView.
The study demonstrated that connexin43 (Cx43) knockout caused arrhythmic phenotype and decreased proline content in vitro and in vivo. Mechanistically, Cx43 interacts with the amino acid transporter SNAT2 (sodium‐dependent neutral amino acid transporter), and its deficiency disrupts proline transport and metabolism.

Embryonal carcinoma in androgen insensitivity syndrome

Indian Journal of Medical and Paediatric Oncology, 2011
Embryonal cell carcinoma is a rare clinical entity. We report a case of a 20-year-old patient who presented with lump lower abdomen for last two months with primary amenorrhea and poorly developed secondary sexual characteristics.

Serum free culture and characterization of human embryonic germ cells [PDF]

Cell Research, 2008
Many proteins and growth factors in serum play important roles in the propagation of embryonic stem (ES) cells. But there are some disadvantages in using the serum to culture ES cells. We examined the effects of a chemically-defined culture system knock-out serum replacement (KSR) in the absence of FBS on the growth and differentiation of human ...

A Testis‐Specific Aralkylamine N‐Acetyltransferase Regulates Dimorphic Sperm Function and Male Fertility in Moths

Advanced Science, EarlyView.
We identify a Lepidoptera‐conserved testis‐specific arylalkylamine N‐acetyltransferase (LTNAT) that governs male moth fertility via a novel mechanism. LTNAT loss disrupts eupyrene sperm mitochondrial derivatives and impairs apyrene sperm motility, offering a safe molecular target for innovative pesticides and genetic pest control.

Nephroblastoma Arising from Primary Testicular Germ Cell Tumor: A Case Report and Literature Review

Case Reports in Pathology, 2016
Adult extrarenal nephroblastoma is a very rare tumor. Nephroblastoma arising from primary testicular germ cell tumor is exceedingly rare. To our knowledge, only three cases have been reported in the English literature.

BMP Inhibition in Seminomas Initiates Acquisition of Pluripotency via NODAL Signaling Resulting in Reprogramming to an Embryonal Carcinoma [PDF]

, 2017
Type II germ cell cancers (GCC) can be subdivided into seminomas and non-seminomas. Seminomas are similar to carcinoma in situ (CIS) cells, the common precursor of type II GCCs, with regard to epigenetics and expression, while embryonal carcinomas (EC ...

β‐Adrenergic Signaling Promotes Anti‐Tumor Immunity in TP53‐mutant Oral Squamous Cell Carcinoma

Advanced Science, EarlyView.
β‐adrenergic stimulation enhances anti‐tumor immunity in TP53‐deficient oral squamous cell carcinoma by inducing tumor‐derived secretion of CXCL10, which attracts and activates cytotoxic CD8+ T cells. The findings demonstrate that β‐adrenergic signaling alters tumor–immune interactions via CXCL10‐mediated paracrine activation, revealing a neuro‐immune ...

Germ-layer commitment and axis formation in sea anemone embryonic cell aggregates [PDF]

Proceedings of the National Academy of Sciences, 2018
Significance Embryonic development of any animal species is a robust series of morphogenetic events tightly controlled by molecular signals. However, the variety of developmental trajectories undertaken by different members of the same phylum suggests that normal development in each particular species might involve only a subset ...

Comparative Single‐Cell Transcriptomic Atlas Reveals the Genetic Regulation of Reproductive Traits

Advanced Science, EarlyView.
A cross‐species single‐cell transcriptomic atlas of reproductive and central nervous system tissues from sheep and humans reveals conserved cellular programs and regulatory networks that regulated fertility. Integration with GWAS for sheep lifetime average litter size identifies UNC5–SLIT–BMP signaling as a core pathway coordinating neuroendocrine ...
