Embryoid body: hESCs in culture spontaneously form ball-like embryo-like structures termed "embryoid bodies", which consist of a core of mitotically active and differentiating hESCs and a periphery of fully differentiated cells from all three germ layers. iPSCs also form embryoid bodies and have peripheral differentiated cells.
p53, also known as Tumor protein P53, cellular tumor antigen p53 (UniProt name), or transformation-related protein 53 (TRP53) is a regulatory protein that is often mutated in human cancers. The p53 proteins (originally thought to be, and often spoken of as, a single protein) are crucial in vertebrates , where they prevent cancer formation. [ 5 ]
For example ESCs have been differentiated into insulin-producing cells, [26] and researchers at Harvard University were able to produce large quantities of pancreatic beta cells from ESCs. [ 27 ] An article published in the European Heart Journal describes a translational process of generating human embryonic stem cell-derived cardiac ...
The symbols for the thirteen macronutrient elements in biology spell CHOPKINS CaFe Mg NaCl, or C. Hopkins Cafe [food tastes] m[ighty] g[ood] with salt (NaCl). Note however, that this popular and useful mnemonic [ 1 ] is typical in that it is neither comprehensive nor context-free.
The p53 upregulated modulator of apoptosis (PUMA) also known as Bcl-2-binding component 3 (BBC3), is a pro-apoptotic protein, member of the Bcl-2 protein family. [5] [6] In humans, the Bcl-2-binding component 3 protein is encoded by the BBC3 gene. [5] [6] The expression of PUMA is regulated by the tumor suppressor p53.
However, as pointed out earlier, many authors make little attempt to follow the letter case or italic guidelines; and regarding protein symbols, they often will not use the official symbol at all. For example, although the guidelines would call p53 protein "TP53" in humans or "Trp53" in mice, most authors call it "p53" in both (and even refuse ...
Specific genes such as p53, NME1, BRCA and PIK3CA/Akt may be associated with responsiveness of the cancer cells to innovative research pharmaceuticals. BRCA1 and BRCA2 polymorphic variants can increase the risk of breast cancer, and these cancers tend to express a pr ofile of genes, such as p53, in a pattern that has been called "BRCA-ness."
There is also debate on if there can be a defined distinction between therapeutic and non-therapeutic germline editing. An example would be if two embryos are predicted to grow up to be very short in height. Boy 1 will be short because of a mutation in his Human Growth Hormone gene, while boy 2 will be short because his parents are very short.
