Research Overview 1
Regulation of Transcription and Molecular Mechanisms of Tumourigenesis
The ‘master weaver of the genome’ protein CTCF is responsible for co-ordinating three-dimensional DNA architecture within the cell nucleus. We have shown that CTCF is a tumour suppressor protein which is frequently inactivated in many cancers. CTCF tightly binds DNA through a central DNA binding domain but has terminal domains on either side with poorly defined function. CTCF has a closely related ‘brother’ protein called BORIS that binds similar DNA sites in the genome. CTCF was reported to be 95% homolog to BORIS in the central DNA binding domain. The similarity present in both proteins draw a possibility of both competing with each other to bind to the same targeted region in the cell. BORIS is a gene which is normally express in the testis and repress in the somatic cell however, it is aberrantly expressed in cancer.
Both proteins CTCF and BORIS exhibit ‘sibling rivalry’ by competing for the same sites in DNA which interferes with CTCF’s tumour suppressor function. Thus, this could lead to the functional differences outcome upon binding to the central region of the DNA and this could be due to the dissimilar sequences present in terminal domains of both DNA. The activation of a gene by CTCF when replace with BORIS at the same targeted region could result in the repression. Hence this could alter the normal physiological functions of the cell and leads to the tumour development. As a cancer testis antigen, restriction BORIS expression to cancer cells and spermatocytes represent an immunotherapeutic avenue for the treatment of many cancers. Hence, BORIS could be potential explore as a new therapeutic marker for the cancer treatment.
