microRNA-205 regulates HER3 in human breast cancer.
An increasing amount of experimental evidence shows that microRNAs can have a causal role in breast cancer tumorigenesis as a novel class of oncogenes or tumor suppressor genes, depending on the targets they regulate. HER2 overexpression is a hallmark of a particularly aggressive subset of breast tumors, and its activation is strictly dependent on the trans-interaction with other members of HER...
متن کاملEvaluation of MicroRNA-99a and MicroRNA-205 Expression Levels in Bladder Cancer
Bladder cancer is the second most common cancer in the genitourinary tract, showing often recurrence and progresse into invasive states. Epigenetic changes, such as microRNA alteration are involved in bladder cancer tumorigenesis through a variety of signaling pathways. The epigenetic state depends on geographic and lifestyle conditions. The aim of this study was to investigate the expression l...
متن کاملMicroRNA-205 signaling regulates mammary stem cell fate and tumorigenesis.
Dysregulation of epigenetic controls is associated with tumorigenesis in response to microenvironmental stimuli; however, the regulatory pathways involved in epigenetic dysfunction are largely unclear. We have determined that a critical epigenetic regulator, microRNA-205 (miR-205), is repressed by the ligand jagged1, which is secreted from the tumor stroma to promote a cancer-associated stem ce...
متن کاملRs3842530 Polymorphism in MicroRNA-205 Host Gene in Lung and Breast Cancer Patients
BACKGROUND The expression of miR-205 is closely related to the occurrence, development, and prognosis of lung cancer and breast cancer. However, studies show that it plays opposite roles in different tumor types. Because the expression and regulation of miR-205 are primarily confined to epigenetic areas, whether genetic variation of miR-205 is related to the occurrence or to the development of ...
متن کاملErbB2 signaling epigenetically suppresses microRNA‐205 transcription via Ras/Raf/MEK/ERK pathway in breast cancer
We previously reported that microRNA-205 (miR-205) is downregulated by overexpression of the receptor tyrosine kinase ErbB2 and that ectopic transfection of miR-205 precursor decreases ErbB2 tumorigenicity in soft agar. In this study, we further analyzed the regulatory mechanisms linking ErbB2 overexpression and miR-205 downregulation. In ErbB2-overexpressing breast epithelial cells, miR-205 ex...
