 Evaluation of nanoformulation Encapsulating Anti-neoplastic Drugs against Oral Squamous Cell Carcinoma

Oral Squamous Cell Carcinoma is one of the most common type of cancer in Indian subcontinent and the current therapy used for its treatment often suffers drawbacks like recurrence of cancer and numerous side effects after the treatment period. This research approach aims to make nanoparticles encapsulating chemotherapeutic agents and their effective combination to combat oral squamous cell carcinoma. The formulation of the nanoparticles aims to provide site specific delivery of the chemotherapeutic drugs directly to the cancer cells thus minimizing the conventional chemotherapy induced side effects. The combination of the chemotherapeutic drugs encapsulated nanoparticles will be evaluated in animal model induced with oral squamous cell carcinoma. In-vivo study involves the study of histopathological changes, pharmacokinetic parameters and bio-distribution studies for the best effective combination of chemotherapeutic drugs. The site specific delivery and the efficacy of the chemotherapeutic drugs will be further confirmed by studying the m-RNA expression levels of different cell cycle regulating genes in the cancer affected tissues. The best combination obtained from the aforementioned studies will be then used in a novel drug delivery system for local application directly to the site of oral cancer. The delivery system will be evaluated both for in-vitro and in-vivo in oral cancer induced animal model to check its efficacy for site specific delivery. The present research study aims to minimize the health cost and side effect associated with the treatment of oral cancer.

Association of Genetic and Immunological markers for prediction of treatment response in Hepatitis C Virus Infection from North East India.


 HCV infection is an important cause of liver disease and remains a major public health problem worldwide. More than 170 million people are chronic carriers of HCV and at high risk of developing liver cirrhosis and/or hepatocellular carcinoma. In India it is estimated that around 1 million people are chronically infected with HCV, with areas such as Northeast India and Punjab representing hotspots of HCV infection.  The backbone of therapy of HCV infection until recently was exogenous addition of antiviral molecule Peg-IFN along with daily Ribavirin, but nowadays direct acting antiviral drugs such as Sofosbuvir and Daclastavir are being used widely along with Ribavirin. The rate of treatment response which was around 80 percent in Peg-IFN/Ribavirin combination therapy although has increased significantly with newer treatment regimes studies have also reported the generation of resistance in HCV strains against some of these new combination therapies. The aim of my research is to identify host factors that influence the effectiveness of treatment in Chronic HCV patients and determine unique predictive markers of treatment response.

Association of Genetic polymorphism towards its predisposition to Nasopharyngeal Carcinoma in Nagaland


 The etiology of NPC is a complex process, with significant interaction of genetic, viral, environmental and dietary factors. Nagaland has the highest incidence of NPC in India. Among host genetic markers implicated with NPC, the major histocompatibility complex (MHC) genes located on chromosome 6 has extensively studied. These genes encode for the very polymorphic human leukocyte antigens (HLA) as well as other genes.HLA complex plays an important role in regulating inflammation, the complement cascade and the innate and adaptive immune responses using the natural killer (NK) and T-cell systems. HLA has shown to have strong and consistent association with NPC in China, Taiwan, Tunisian, etc populations. This study seeks to carry out high resolution typing of the HLA class I and class II to understand its role with NPC in Nagaland. DNA repair systems are indispensable for the maintenance of genome integrity. The genetic polymorphisms in DNA repair genes can lead altered efficiency of DNA repair. This can result in increased genetic instability, and hence susceptibility in developing cancer. Study of the polymorphisms of nucleotide-excision repair and base excision repair genes for their implication in NPC will be carried out. The dietary habits of the Nagas are quite peculiar, which mainly includes fermented and smoked dried food items which might be play a crucial role for the onset of NPC. Analysis of the local dietary food samples will be done to detect the presence of poly aromatic hydrocarbons and nitrosamines.

Association of certain genes in the Transforming Growth Factor-β Signaling Pathway and risk of esophageal Cancer in Northeast India


The transforming growth factor-β (TGF-β) superfamily, which comprises 33 different ligands in mammalian cells, plays a fundamental role in development and maintenance of tissue homeostasis. These ligands regulate key cellular processes, such as proliferation, motility, differentiation, and apoptosis. Dysregulation- of the TGF-b signal transduction pathway resulting from mutations of its core components has been associated with a number of human diseases, including cancer and vascular disorders. As a result, a significant effort of clinical research focuses on developing therapies targeting the TGF-β pathway .

Smad family members play an essential role in regulation of gene expression in the TGF β signalling pathway. Activated smads causes their translocation from the cytoplasm to the nucleus and act as transcription factors. The importance of the TGF-β signalling pathway in cancer has been supported in numerous studies. It is plausible biologically that this pathway may influence prognosis as well as initial disease development given its role in influencing angiogenesis, inflammation, and growth factors. The role of TGF-β signalling in oesophageal cancer has recently been elucidated. Although mutation of these genes is rare in esophageal cancer, alteration of the expression of these mediators correlates with tumour progression and poor prognosis. This study will focus on the associations between genetic variability in the TGF-β signalling pathway and risks of esophageal cancer. We also focus on how diet  and lifestyle factors in combination with genetic variation in key elements of the TGF-β signalling pathway, including Smad genes alters esophageal cancer risk.

Role of Anaphase promoting complex or cyclosome, local food habits and environmental factors in the development of Esophageal cancer from Northeast India

The multimeric protein( Anaphase promoting Complex) needs coactivator to activate. Its activity depends on the association of one of two coactivator subunits (either Cdc20 or Cdh1) that specify substrate recognition and stimulate the catalytic activity of APC/C–E2 complexes the large core protein APC/C  Many regulatory protein  such as cyclins, CDK  inhibitors, transcription factors are regulated by ubiquitin- dependent proteolytic pathway.The  Cascade of enzymes E1,E2 and E3 that catalyze the substrate ubiquitin attachment to form polyubiquitinated conjugate that are rapidly  detected and degraded by 26s proteasome. Knowledge UbE3 ligase are very limited at present. The best characterized E3 ligase is the APC (Anaphase Promoting Complex), which plays a crucial role to promote the cell through anaphase.My aim to study  the expression, the different subunit of Anaphase Promoting Complex in oesopahgeal cancer patients compairing with controll.

Genetic Polymorphism of Human Leucocyte Antigen (HLA) and Immunomodulation of Inflammatory Cytokines in Influenza Infected Population of Assam.

Influenza virus remains a significant health concern affecting millions each year with the threat of newly emerging strains that are diverse enough to be virulent, affecting different human populations differently. Many genetic components impact the severity of influenza disease. One such component is a person’s human leukocyte antigen (HLA) which are very diverse and binds pathogen antigens to which our immune response can depend heavily. Thus differences in one’s HLA alleles can drastically affect immune responses and disease outcome. So the present study is aimed to identify the genetic polymorphism of HLA class I and class II alleles in severe and mild cases of influenza positive and their immune response by cytokine production, in correlation with healthy controls. While sequence analysis between severe and mild cases will be done to point the mutation pattern of HLA. Identification of such host factor may be used as a target for therapeutic development with changing influenza pathogenicity.
