After completing a masters from Mumbai University, Farjana worked as a researcher in molecular microbiology at PD Hinduja National hospital & MRC (Mumbai). Her research career in UK started with a doctorate at Keele.

Currently as a brain tumour UK postdoctoral fellow, Farjana is investigating molecular mechanisms underlying chemo-resistance in WHO grade IV astrocytoma.

Micro-RNA Expression Profiling to identify Novel Therapeutic targets in High-Grade Astrocytoma Cultures

Introduction
Malignant astrocytoma is most common and aggressive type of tumour of the central nervous system. Despite improvements in surgery, radiation and chemotherapy, prognosis of patients   is <1 year. miRNAs are anti-gene molecules which alter expression of specific genes. They are implicated in the initiation and progression of multiple cancers and in the development of resistance to chemotherapeutic drugs.

Aims & Objectives
The primary aim was to investigate the expression of these miRNAs in aggressive brain tumour cells (short-term high grade astrocytoma cultures) derived from patients. Secondly to investigate the role of specific miRNA in the development of resistance to common chemotherapeutic drugs.                                         

Methods
miRNA was extracted from the panel of aggressive brain tumour cells and were tested for their miRNA expression pattern on microarrays chips. Microarray is a high throughput technology that allowed rapid and multiple testing of these anti-gene molecules.

Research design
The data generated were analyzed to recognize miRNA expression pattern that are specific for cells resistant to chemotherapeutic drugs.

Summary findings
The current study enabled identification of handful of miRNA targets that may be useful in predicting p53 status of the tumours (miR-145, miR221), chemo-sensitivity to Vincristine (miR-145, miR221) and Doxorubicin (miR-3960, miR-21) which could potentially allow customization of treatment strategy. In addition, the current study also has enabled identification of cell growth associated (miR-22, miR125b) and oncogenic (miR-221, miR-125b, miR-23a, miR-720) miRNAs. The validation experiments for these target miRNAs are being currently conducted.

Conclusion
These results potentially could lead to the development of novel therapeutic strategies to treat patients with aggressive type of adult brain tumour.
