MicroRNA-dependent inhibition of WEE1 controls cancer stem-like characteristics and malignant behavior in ovarian cancer.

Cancer stem-like cells (CSCs) have been suggested to be responsible for chemoresistance and tumor recurrence owing to their self-renewal capacity and differentiation potential. Although WEE1 is a strong candidate target for anticancer therapies, its role in ovarian CSCs is yet to be elucidated. Here, we show that WEE1 plays a key role in regulating CSC properties and tumor resistance to carboplatin via a microRNA-dependent mechanism.

Total vaginectomy and radical vulvectomy for extension of extra-mammary Paget's disease.

Extra-mammary Paget's disease of the vulva is a rare non-invasive adenocarcinoma that usually occurs in postmenopausal women. Histologically, it often extends beyond the visible lesion, leading to positive surgical margins and frequent recurrences, but can be managed by simple vulvectomy or wide local excision. Although current evidence supports the use of radical surgery as an alternative to the generally performed wide local excision in the treatment of widely extended extra mammary Paget's disease of the vulva, nonetheless there controversy still exists regarding the extent of an adequate resection margin.

Cyclophilin A regulates JNK/p38-MAPK signaling through its physical interaction with ASK1.

Cyclophilin A (CypA), a member of the immunophilin family, is predominantly localized in the cytoplasm. The peptidylprolyl isomerase (PPIase) activity of CypA has been demonstrated to be involved in diverse cellular processes, including intracellular protein trafficking, mitochondrial function, pre-mRNA processing, and maintenance of multiprotein complex stability. In this study, we have demonstrated that CypA regulates apoptosis signaling-regulating kinase 1 (ASK1) through its direct binding.

Umbilical cord tissue-derived mesenchymal stem cells induce apoptosis in PC-3 prostate cancer cells through activation of JNK and downregulation of PI3K/AKT signaling.

Introduction: Although mesenchymal stem cells (MSCs) have antitumor potential in hepatocellular carcinoma and breast cancer cells, the antitumor mechanism of human umbilical cord mesenchymal stem cells (hUCMSCs) in prostate cancer cells still remains unclear. Thus, in the present study, we elucidated the antitumor activity of hUCMSCs in PC-3 prostate cancer cells in vitro and in vivo.

Methods: hUCMSCs were isolated from Wharton jelly of umbilical cord and characterized via induction of differentiations, osteogenesis, and adipogenesis.
