BIO 2133 Lecture Notes - Lecture 6: Adipose Tissue, Gene Expression, Mitosis
Document Summary
Spatial regulation: red blood cells, neurons, connective tissues, bone cells, adipose tissue, intestinal cells, muscle. Temporal regulation: based on time, different times of the life cycle, different cell development, temporal regulation of globin, fetal hemoglobin can extract more oxygen from blood than adult hemoglobin. Conditional regulation: training / conditions that will help enhance certain phenotypes and appearances, unnatural factors, example: steroids, tanning, pregnancy, learning depending on the condition we can have different gene expression. Deficiency in pathways can affect how something is metabolized, or how a gene is expressed. In an entire pathway, not all the cells will express a certain step at once, only certain ones. Cell differentiation: single cell: mitosis, turns into daughter cell, turns into a muscle or a skin cell, stress response, no stress no expression of stress response genes, stress expression. Example: fish adaptation in response to stressful situations.
