WitrynaA screen of 119 CS patients negative for PTEN mutation at the coding region showed that 10% had mutations located at the promoter region between −1344 and −745 bp upstream of the translation start codon. 4 It was estimated that mutations at the promoter might result in post-translational modifications or targeted PTEN degradation, thereby ... WitrynaThe surface area of the plasma membrane limits the exchange of materials between a cell and its environment. Some cells are specialized in the exchange of wastes or nutrients and have modifications to increase the area of the plasma membrane. For instance, the membranes of some nutrient-absorbing cells are folded into fingerlike …

WitrynaAs the blood is pumped through this capillary network, gas exchange occurs. Although a small amount of the oxygen is able to dissolve directly into plasma from the alveoli, most of the oxygen is picked up by erythrocytes (red blood cells) and binds to a protein called hemoglobin, a process described later in this chapter. WitrynaFunctionally, gap junctions in animal cells are a lot like plasmodesmata in plant cells: they are channels between neighboring cells that allow for the transport of ions, water, and other substances ^3 3. Structurally, however, gap junctions and plasmodesmata are quite different. In vertebrates, gap junctions develop when a set of six membrane ...
