The corpus luteum (CL) is a transient endocrine structure formed from the remnants of an ovulated follicle with the primary purpose of producing progesterone (P4), a hormone vital for the establishment and maintenance of ...

A large number of evolutionarily conserved genes have been identified by comparative genomics approaches. However, a considerable fraction of these genes lack functional characterization despite the availability of several ...

Cancer progression is a multi-step process requiring cells to acquire specific properties that aid the neoplastic growth. One such property is the ability to survive in the absence of matrix-attachment, a critical necessity ...

Transforming growth factor-β (TGF-β) superfamily of cytokines comprises of several members, which can broadly be sub-divided into three classes [TGF-βs, Activin/Nodal, and Bone morphogenetic proteins (BMPs)]. Most members ...

Bacteria lack nucleus and any other membrane-bound organelles. Hence all the cellular components, including proteins, DNA, RNA and other components are located within the cytoplasm. The region of the cell which encompasses ...

RAGs (Recombination Activating Genes) are responsible for generation of antigen receptor diversity in case of B-cells and T-cells, through the process of combinatorial joining of different V (variable), D (diversity) and ...

The sequence of a polypeptide chain determines its structure which in turns determines its function. A protein is stabilized by multiple forces; hydrophobic interaction, electrostatic interactions and hydrogen bond formation ...

Melanosome biogenesis is a highly regulated endosomal maturation process wherein structural fibers harbouring immature melanosomes acquires its biosynthetic proteins through the secretory pathway and finally matures into ...

The transition to flowering is an important decision for plants since seed-setting and the survival of the progeny depend on the environmental conditions prevalent during this transition. Therefore, to ensure maximum ...

Vision is computationally challenging because objects in the real world can change in size, position, viewpoint etc., and therefore cast a myriad images on the retina. Viewpoint changes are particularly challenging because ...
