In vitro investigation of putative interactions between the RING finger domain of Retinoblastoma Binding Protein 6 (RBBP6) and various substrates
(University of the Western Cape, 2015)Retinoblastoma Binding Protein 6 (RBBP6) is a RING finger-containing protein which plays a critical role in the 3'-end processing of mRNA transcripts. It is a constituent of the human pre-mRNA processing complex but also ... -
An in vitro investigation of the effects of camellia sinensis and aspalathus linearis on benign (RPWE 1) and malignant (LNCaP) prostate cell lines
(University of the Western Cape, 2015)The prostate is prone to three pathological processes that include inflammation, benign prostate hyperplasia (BPH) and tumors. According to the center for Disease and Control 1999-2012 report, prostate cancer is the second ... -
In vitro investigation of the ubiquitination and degradation of p53 by Murine Double Minute 2 (MDM2) and Retinoblastoma Binding Protein 6 (RBBP6)
(University of the Western Cape, 2015)P53 is one of the most important tumour suppressor proteins in the body which protects the cell against the tumourigenic effects of DNA damage by initiating processes such as apoptosis, senescence and cell cycle arrest. ... -
In vitro modulatory effects of fermented rooibos extract (Aspalathus linearis) against ethanol-induced effects on the mouse blood-brain barrier
(University of the Western Cape, 2014)Alcohol abuse is a growing crisis within South Africa, with severe health and socio-economic implications. Alcohol compromises the function of the blood-brain barrier (BBB), and thus its ability to regulate the homeostatic ... -
