Open AccessInvolvement of polypyrimidine tract-binding protein (PTBP1) in maintaining breast cancer cell growth and malignant properties
We have investigated some roles of splicing factor polypyrimidine tract-binding protein (PTBP1) in human breast cancer. We found that PTBP1 was upregulated in progressively transformed human mammary epithelial...

Knockdown of splicing factor SRp20 causes apoptosis in ovarian cancer cells and its expression is associated with malignancy of epithelial ovarian cancer
Our previous study revealed that two splicing factors, polypyrimidine tract-binding protein (PTB) and SRp20, were upregulated in epithelial ovarian cancer (EOC) and knockdown of PTB expression inhibited ovaria...

Knockdown of polypyrimidine tract-binding protein suppresses ovarian tumor cell growth and invasiveness in vitro
Polypyrimidine tract-binding protein (PTB) is an RNA-binding protein with multiple functions in the regulation of RNA processing and IRES-mediated translation. We report here overexpression of PTB in a majorit...

Alkaloids
Despite the historic roles of colchicine (and certain of its derivatives) and, subsequently, of the Vinca alkaloids, not only as probes that have expanded our fundamental knowledge of cell biology, but also as im...

Why Is Tumor tRNA Hypomodified with Respect to Q Nucleoside?
Nucleoside Q is found exclusively in the first position of the anticodon in tRNATyr, tRNAHis, tRNAAsn, and tRNAAsp (Kasai et al. 1975b, 1976). Its function is unknown, and long-term Q-deficient, germ-free mice ap...
