1. The significance of urokinase-type plasminogen activator (u-PA) in tumour growth and Linomide-induced upregulation of u-PA's endogenous inhibitor PAI-2
Abstract : The progressive process of tumour invasion and generation of metastases is the primary cause of death for most patients with cancer. Some of the regulatory components of this progressive process are adhesion, migration, and proteolysis. READ MORE

Abstract : DNA methylation is an epigenetic mechanism that regulates the gene transcription. Folate is used in cellular synthesis of methyl groups, nucleic acids and amino acids.

Of all the known HERV groups, the HERV-K supergroup apparently comes closest to encoding functional retroviral proteins, although infectious particles have not been demonstrated. READ MORE
