Letrozole, sold under the brand name Femara among others, is an aromatase inhibitor medication that is used in the treatment of breast cancer for post-menopausal women. [1]It was patented in 1986 and approved for medical use in 1996. [4]
Molecular classification of breast cancer from mRNA expression profiles. DNA microarrays have compared normal cells to breast cancer cells and found differences in the expression of hundreds of genes. Although the significance of many of those genetic differences is unknown, independent analyses by different research groups has found that ...
Worldwide, breast cancer is the leading type of cancer in women, accounting for 25% of all cases. [5] It is most common in women over age 50. Signs of breast cancer may include a lump in the breast, a change in breast shape, dimpling of the skin, fluid coming from the nipple, a newly inverted nipple, or a red or scaly patch of skin. [6]
In triple-negative breast cancer (TNBC), oncogenic activation of the PI3K/AKT/mTOR pathway can happen as a function of overexpression of upstream regulators like EGFR, activating mutations of PIK3CA, loss of function or expression of phosphatase and tensin homolog (PTEN), and the proline-rich inositol polyphosphatase, which are downregulators ...
Tissue differentiation antigens are those that are specific to a certain type of tissue. Mutant protein antigens are likely to be much more specific to cancer cells because normal cells shouldn't contain these proteins. Normal cells will display the normal protein antigen on their MHC molecules, whereas cancer cells will display the mutant version.
The individual does not develop cancer at this point because the remaining TSG allele on the other locus is still functioning normally. Second Hit: While the second hit is commonly assumed to be a deletion that results in loss of the remaining functioning TSG allele, the original published mechanism of RB1 LOH was mitotic recombination / gene ...
The filtration cassette captures a plethora of different cancer cell types. In May 2022, the Parsortix PC1 system was cleared by the FDA as a medical device for the capture and harvest of circulating tumor cells (CTCs) from metastatic breast cancer patient blood for subsequent analysis.
