RNA silencing refers to a conserved RNA-directed gene regulatory mechanism in a wide range of eukaryotes. It plays an important role in many processes including growth, development, genome stability, and antiviral defense in the plants. Geminivirus encoded AC2 is identified as an RNA silencing suppressor protein, however, the mechanism of action has not(More)
Site-specific recombination tools such as the Cre–loxP system are used to create animal models where conditional gene deletion/activation studies are required. In the current proof of principle study, we have demonstrated that a PET reporter gene (PRG), the herpes simplex virus type 1 thymidine kinase (HSV1-tk), can be made to remain silent and can be(More)
INTRODUCTION Human immunodeficiency virus type 1 (HIV-1), HIV-2, and simian immunodeficiency virus all use chemokine receptors (CCR5, CXCR4, and minor receptors) to gain entry into a susceptible cell and establish infection successfully by way of membrane fusion. Many such chemokine receptors that can act as entry cofactors under in vitro conditions have(More)
