Worked on the role of LTβ/LTβR signal activation of the alternative NF-kB pathway in Head and Neck Squamous Cell Carcinomas. Established that the LTβ/LTβR alternative path way is constitutively activated and involves stabilization of NF-kB Inducing Kinase, activation of Inhibitor Kappa B Kinase-α and the processing of p100/RELB into p52/RELB.

Using genetic and pharmacologic inhibitors, obtained evidence that NIK and downstream NF-kB alternate pathway transcription factor, RELB, contribute to cell migration, a key hallmark of the malignant phenotype and metastasis of HNSCC.

ADDITIONAL INFORMATION:

Additional Research:

Gene expression in gliomas involving preparation of glioma cDNA expression library in λgt 11 vector from glioma isolated mRNA and screening with bc1-2 probe. Characterized plaque purified clones by Southern blots, Northern blots and sequence analysis, and used both manual and automatic sequencing from the forward and complementary strands.

Isolated and used genomic DNA from tumors and MNC DNA from the blood of the respective patients on the Southern blots to detect restriction fragment polymorphism using glioma library isolated cDNA clones.

Prepared Northern blots with the mRNA isolated from the gliomas and probed with the cDNA to detect the expression of the gene in gliomas. Conducted In vitro transcription and translation to detect the size of the expressed protein product of the cloned cDNA under the control of the E.coli phage T7 RNA polymerase promoter. Protein expression was done in QIA express system and the recombinant proteins were purified. Conducted Western blot analysis of the protein using bc1-2 monoclonal antibody (published).

Used purified protein as an antigen to raise poly-clonal antibody in rabbits and this antibody was affinity purified by sepharose 4B and used to screen a normal brain cDNA expression library. Isolated four normal brain clones and characterizations of these clones to determine the structure of the full-length normal RNA expressed in brain. Used antibodies in immunohistochemistry studies to analyze the expression of protein in glioma sections. Performed RT-PCR and in situ hybridization of the amplified mRNA on tissue sections to characterize the expression of the genes in glioma sections (published).

Extensive research experience with Giardia lamblia trophozoites as the antigen to detect anti- Giardia lamblia antibodies in serum of patients (published).
