Abstract

Apoptotic markers in breast cancer are reported to have prognostic significance. The aim of this study was to assess the prognostic value of Akt, phospho-Akt and BAD expression in primary tumours from breast cancer patients. Expression of phospho-Akt did not correlate with menopausal status, nodal involvement or tumour size, although there was a significant correlation between phospho-Akt and oestrogen receptor status and tumour grade. No association was found between phospho-Akt and BAD. However, a significant correlation was found between Akt and BAD. Akt and phospho-Akt expression did not correlate with either disease-free survival (DFS) or overall survival (OS). Conversely, BAD immunostaining correlated significantly with increasing tumour size and with oestrogen receptor (ER) immunostaining in both frozen and paraffin sections. Expression of BAD appeared to be nucleolar in addition to its cytoplasmic and nuclear staining. Comparison of immunohistochemical staining on frozen sections and paraffin sections showed a reasonable concordance in Akt and BAD immunoreactivity. However, the results showed for the first time that strong BAD expression is related to a favourable prognosis but is not an independent prognostic factor. I...Continue Reading

AKT Pathway

This feed focuses on the AKT serine/threonine kinase, which is an important signaling pathway involved in processes such as glucose metabolism and cell survival.

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
