The BDNF Val66Met polymorphism serves as a potential marker of body weight in patients with psychiatric disorders.

Brain-derived neurotrophic factor (BDNF) is a predominant neurotrophic factor in the brain, indispensable for neuronal growth, synaptic development, neuronal repair, and hippocampal neuroplasticity. Among its genetic variants, the BDNF Val66Met polymorphism is widespread in the population and has been associated with the onset and aggravation of diverse pathologies, including metabolic conditions like obesity and diabetes, cardiovascular ailments, cancer, and an array of psychiatric disorders. Psychiatric disorders constitute a broad category of mental health issues that influence mood, cognition, and behavior.

Perspectives on miRNAs directly targeting BDNF for cancer diagnosis and treatment (Review).

MicroRNA (miRNA), a non‑coding single‑stranded RNA molecule with a length of 21‑25 nucleotides transcripts, has been identified to play important roles in tumorigenesis and shows great potential applications in cancer diagnosis, prognosis and therapy. Brain derived neurotrophic factor (BDNF) is a member of the nerve growth factor family and usually serves as a biomarker in neurological and neuropsychiatric diseases for diagnosis and treatment by regulating its high‑affinity receptor TrkB (Tyrosine Kinase Receptor B). Abnormal expression of BDNF is also closely related to the development of cancer, cancer‑related pain and depression.

Caveolin-1 affects tumor drug resistance in esophageal squamous cell carcinoma by regulating expressions of P-gp and MRP1.

Esophageal squamous cell carcinoma (ESCC) is the most common cancer in China, and multidrug resistance (MDR) remains one of the biggest problems in ESCC chemotherapy. In this study, we aimed to investigate the mechanism of Caveolin-1, an integral membrane protein, on regulating ESCC MDR. First, immunohistochemistry was used to check the protein expression of Caveolin-1, MDR-related protein of P-glycoprotein (P-gp), and multidrug resistance protein 1 (MRP1) in 84 pathologically characterized ESCC tissues, matched adjacent tumor, and adjacent normal-looking tissues.

Identification of Z-OTU protein during zebrafish oogenesis and early embryogenesis.

Zebrafish (Danio rerio) Z-OTU, containing OTU and TUDOR domains, was predicted to be a member of OTU-related protease, a family of the deubiquitylating enzymes (DUBs). A previous report from our laboratory clearly describes the expression patterns of z-otu mRNA. Here, we characterized the Z-OTU protein during zebrafish oogenesis and early embryogenesis.

Identification and characterization of TSAP, a novel gene specifically expressed in testis during spermatogenesis.

Through in silico screens, we have identified many previously uncharacterized genes that display similar expression patterns as the mouse Dazl gene, a germ line-specific marker. Here, we report the identification and characterization of one of these novel genes. TSAP gene encodes a protein with 350 amino acids and contains five ankyrin repeats and a PEST sequence motif.
