Journal ArticleDOI
Subgenotypes of hepatitis B virus genotype D (D1, D2, D3 and D5) in India: differential pattern of mutations, liver injury and occult HBV infection.
Partha K. Chandra,Avik Biswas,Sibnarayan Datta,Arup Banerjee,Rajesh Panigrahi,Shekhar Chakrabarti,Binay Krishna De,Runu Chakravarty +7 more
TL;DR: Hepatitis B genotype D subgenotypes differ in their mutational patterns in the S, polymerase and the BCP/PreC regions that may influence their clinical outcomes, and these patterns were observed from both northern and eastern Indian HBV/D3 isolates.
Journal ArticleDOI
Anti-hepatitis B core antigen testing with detection and characterization of occult hepatitis B virus by an in-house nucleic acid testing among blood donors in Behrampur, Ganjam, Orissa in southeastern India: implications for transfusion.
Rajesh Panigrahi,Avik Biswas,Sibnarayan Datta,Arup Banerjee,Arup Banerjee,Partha K. Chandra,Partha K. Chandra,Pradip Kumar Mahapatra,Bharat Patnaik,Sekhar Chakrabarti,Runu Chakravarty +10 more
TL;DR: Addition of antiHBc testing for donor screening, although will lead to rejection of a large number of donor units, will definitely eliminate HBV infected donations and help in reducing HBV transmission with its potential consequences, especially among the immunocompromised population.
Journal ArticleDOI
Tumor suppressor micro RNA miR-145 and onco micro RNAs miR-21 and miR-222 expressions are differentially modulated by Hepatitis B virus X protein in malignant hepatocytes
Manikankana Bandopadhyay,Arup Banerjee,Neelakshi Sarkar,Rajesh Panigrahi,Rajesh Panigrahi,Sibnarayan Datta,Ananya Pal,SP Singh,Avik Biswas,Shekhar Chakrabarti,Runu Chakravarty +10 more
TL;DR: The study throws light into possible way by which HBx protein acts through microRNA and thereby regulates host functioning and might suggest new therapeutic strategies against hepatic cancer.
Journal ArticleDOI
Frequency and significance of hepatitis B virus surface gene variant circulating among ‘antiHBc only’ individuals in Eastern India
Arup Banerjee,Partha K. Chandra,Sibnarayan Datta,Avik Biswas,Prasun Bhattacharya,Subhasis Chakraborty,Sekhar Chakrabarti,Sujit K. Bhattacharya,Runu Chakravarty +8 more
TL;DR: The existence of occult HBV infection among antiHBc only individuals could not be explained fully by mutations in the 'a' determinant region of surface gene in the population.
Journal ArticleDOI
Genetic characterization of hepatitis B virus in peripheral blood leukocytes: evidence for selection and compartmentalization of viral variants with the immune escape G145R mutation.
Sibnarayan Datta,Rajesh Panigrahi,Avik Biswas,Partha K. Chandra,Arup Banerjee,Pradip Kumar Mahapatra,C K Panda,Shekhar Chakrabarti,Sujit K. Bhattacharya,Kuntal Biswas,Runu Chakravarty +10 more
TL;DR: Evidence is provided in favor of the compartment-specific abundance, evolution, and emergence of the potent immune escape mutant in hepatitis B virus sequences from the peripheral blood leukocytes of a large set of subjects.
