Cyclin D1b in human breast carcinoma and coexpression with cyclin D1a is associated with poor outcome.
BACKGROUND/AIM Cyclin D1 is a mediator of cell-cycle control that is frequently overexpressed in primary ductal breast carcinomas, but its role is controversial. A polymorphism in the CCND1 gene, G870A, results in an aberrantly spliced protein (cyclin D1b) lacking the Thr-286 phosphorylation site necessary for nuclear export. Studies of murine fibroblasts have shown that although overexpression...
متن کاملPredictive Factors of Quality of Life in Patients with Colorectal cancer
Introduction: Colorectal cancer is one of the most common invasive cancers, and is ‎responsible for physical and psychosocial morbidity. Therefore, Quality of Life (QOL) is an ‎important outcome for these patients. Although extensive research has examined QOL in ‎patients with colorectal cancer, less research has examined factors that predict QOL. ‎ Objective: The aim o...
متن کاملPrognostic and predictive factors in colorectal cancer.
Prognostication of newly diagnosed colorectal cancer (CRC) predominantly relies on stage as defined by the UICC-TNM and American Joint Committee on Cancer classifications. Tumour extent, lymph node status, tumour grade and the assessment of lymphatic and venous invasion are still the most important morphological prognostic factors. Evidence suggests that tumour budding and tumour border configu...
متن کاملCyclin D1b variant influences prostate cancer growth through aberrant androgen receptor regulation.
Cyclin D1 is a multifaceted regulator of both transcription and cell-cycle progression that exists in two distinct isoforms, cyclin D1a and D1b. In the prostate, cyclin D1a acts through discrete mechanisms to negatively regulate androgen receptor (AR) activity and thus limit androgen-dependent proliferation. Accordingly, cyclin D1a is rarely overexpressed in prostatic adenocarcinoma and holds l...
