Summary of Research
Cancer metastasis is a hallmark of malignancy, contributing to about 90% of human cancer deaths. Tumor cells often uses vascular as well as lymphatic system for their metastatic spread. Therefore, understanding the underlying molecular mechanisms of angiogenesis and lymphangiogenesis is highly important. Previously we have shown thatC/EBP-d (CCAAT/enhancer-binding protein-d),a transcription factor along with hypoxia inducible factor 1 (HIF-1) plays a pivotal role in regulation of angiogenesis as well as lymph-angiogenesis through respective vascular growth factors. Furthermore, inactivation of C/EBP-d in mice model led to a significant reduction of VEGF-C /VEGFR3 signalling in the lymphatic endothelium and pulmonary metastasis. Our findings also provided a molecular mechanism for supporting the role of C/EBP-d in cell motility, vascular network formation, cell survival in lymphatic endothelium and finally towards tumor progression.
Subsequent work also revealed thathow an adherent junction protein, d-catenin regulates lymphatic endothelial cell motility and lymphangiogenesis with the involvement of RhoGTPase. Significantly there were a delay of tumor formation, growth and metastasis due to absence of single or both allele of d-catenin, suggesting vitalparticipation ofd-catenin in tumor metastasis.
Our work on endothelial dysfunction in relation to pulmonary arterial hypertension implicated the contribution of SRC kinase -dependent caveolar mis-trafficking in pulmonary endothelial cells during pulmonary endothelial barrier dysfunction among pulmonary arterial hypertension patients.
- Investigating the angiogenic signalling pathway involve in hepatocellular carcinoma (HCC).
- Find out the specific anti-angiogenic factors to develop strategies for effective antitumor effect.
My long term research goals:
- Identify specific growth factors in blood or bone marrow, whichcan be useful as biomarkers for early diagnosis of cancer in new patients as well as in case of relapse.
