p27Kip1 and Ser10-phosphorylated p27Kip1 in breast cancer: clinical significance and expression

p27Kip1 and Ser10-phosphorylated p27Kip1 in breast cancer: clinical significance and expression

BACKGROUND The protein p27 (p27(Kip1)) is a member of the cyclin-dependent kinase inhibitor family, which negatively regulates cell cycle progression, and the phosphorylation of p27 has been proven to affect its stability and nuclear export. Clinical studies on the relation between p27 and phosphorylated p27 (p-p27Ser10) in breast invasive ductal carcinomas are still scarce. METHODS We examin...

Expression and Clinical Significance of Activating Transcription Factor 3 in Human Breast Cancer

  Objective(s): Breast cancer is the most common type of cancer among women worldwide. This study investigated the expression and clinical significance of activating transcription factor 3 (ATF3) in human breast cancer and its relationship with the clinical outcome of breast cancer.   Materials and Methods : ATF3 expressions were detected in 114 primary breast cancer tissues and ...

MIB-1 and p27Kip1 expression in nephroblastoma.

Augmented expression levels of lncRNAs ecCEBPA and UCA1 in gastric cancer tissues and their clinical significance

Objective(s): As the second cause of cancer death, gastric cancer (GC) is one of the eminent dilemmas all over the world, therefore investigating the molecular mechanisms involved in this cancer is pivotal. Unrestricted proliferation is one of the characteristics of cancerous cells, which is due to deficiency in cell regulatory systems. Long non-coding RNAs (lncRNAs) have emerged as critical re...

Peptide nucleic acids targeting miR-221 modulate p27Kip1 expression in breast cancer MDA-MB-231 cells.

The activity of a peptide nucleic acid (PNA) targeting cancer-associated microRNA-221 is described. PNAs against miR-221 were designed in order to bind very efficiently to the target RNA strand and to undergo efficient uptake in the cells. A polyarginine-PNA conjugate targeted against miR-221 (Rpep-PNA-a221) showed both very high affinity for RNA ...
