The oncogenic isoform of the p63 protein, delta Np63 (delta Np63), plays an important role in the pathogenesis of many epithelial carcinomas, and emerging evidences suggest that delta Np63 is a promising drug target. However, the functions of delta Np63 in transitional cell carcinoma of bladder (TCCB) are poorly defined. In this study, a delta Np63 shRNA expression vector was transfected into T...

Some researchs have demonstrated that the loss of delta Np63 is associated with aggressive phenotypes and poor prognosis. However, other research indicates that delta Np63 is considered to have oncogenic properties. Delta Np63 overexpression is often observed in association with the oncogenic growth of squamous cell carcinomas and bladder cancer. In this study, we investigated the oncogenic rol...

Uropathogenic E. coli (UPEC) is the primary cause of urinary tract infections (UTI) affecting approximately 150 million people worldwide. Here, we revealed the importance of transcriptional regulator hypoxia-inducible factor-1 α subunit (HIF-1α) in innate defense against UPEC-mediated UTI. The effects of AKB-4924, a HIF-1α stabilizing agent, were studied using human uroepithelial cells (5637) a...

The effects of media conditioned by leukemic cells from 11 acute myeloblastic leukemia patients on the growth of autologous blast progenitors were studied. First, it was shown that T-cell-depleted leukemic cells from some patients release high levels of colony-stimulating activity into the culture medium, whereas following further depletion of phagocytic cells, the levels of colony-stimulating ...

We studied the biological effects of pluripoietin, a human pluripotent hemopoietic colony-stimulating factor (CSF) purified from the 5637 bladder carcinoma cell line. We found that this human CSF appears to be a unique hemopoietic growth factor, differing from interleukin 3 (IL-3) by virtue of its leukemia differentiating activity in mouse and man, and from mouse granulocyte CSF, which does hav...

Platycodin D is an active component isolated from Chinese herb Platycodonis radix with various pharmacological activities, such as antitussive, expectorant, anti-inflammatory, and analgesic effects. Interestingly, platycodin also exerts anticancer effects against several types of cancer. However, few studies on the anti-tumour urinary bladder cancer have been reported. In this study, we explore...
