1. THE HYPOXIC HEMATOPOIETIC STEM CELL NICHE Consequences of Hypoxia-induced Transcription on Stem Cell Fate
Abstract : Hematopoiesis is the process of blood formation that originates with the hematopoietic stem cell (HSC), a cell type that is responsible for the life-long supply of mature blood cells. HSCs are defined by their ability to self-renew as well as giving rise to differentiated cells of all blood lineages. READ MORE

2. Directing Angiogenesis : Cellular Responses to Gradients in vitro
Abstract : Blood vessels are essential for the delivery of nutrients and oxygen to tissues, as well as for the removal of waste products. Patients with tumors, wounds or diabetes all have active angiogenesis, formation and remodeling of blood vessels, a process that is initiated and manipulated by gradients of secreted signaling proteins.

3. Responses to Tumour initiating factors and Regulation of Normal and Malignant Haematopoiesis
Abstract : The haematopoietic stem cell (HSC) resides within a specific environment enabling it to retain its self-renewal capacity or quiescent state. It is proposed that the HSC niche is hypoxic, a milieu within which the HSC is protected from intrinsic and extrinsic stimuli. READ MORE

4. The role of HIF-1alpha in epigenetic regulation of transcription
Abstract : The oxygen level inside cells, determine the amount of HIF protein. By directly being involved in HIF protein turnover rates, through a mechanism, by which, oxygen is utilized as a co-factor, for the PHD enzymes, regulating HIF protein stability. READ MORE

5. Relation between nutritional status, the outcome of infection and immune responses
Abstract : A causal interaction between nutrition and the outcome of different infections has been known since long time ago. Moreover, responses of human beings to infection are diverse and demarcated by immunity. A deficient and unappropriated nutrition allows to a deficient immune response. READ MORE
