Part Descriptions
LP61787-5 PTEN gene
Phosphatidylinositol 3,4,5-trisphosphate 3-phosphatase and dual-specificity protein phosphatase PTEN, also known as phosphate and tensin homolog or PTEN protein, is encoded by the PTEN gene on chromosome10q23.31. PTEN protein has multiple functions, including protein phosphatase and lipid phosphatase activity. The lipid phosphatase function is critical for its role as a tumor suppressor and modulating cell cycle progression and cell survival. It also plays a role in correct neuron positioning, dendritic development and synapse formation, and may be a negative regulator of insulin signaling and glucose metabolism in adipose tissue. Mutations in the PTEN gene are associated with multiple disorders, including PTEN hamartoma tumor syndromes, which include Cowden syndrome and Lhermitte-Duclos disease, squamous cell carcinoma of the head and neck, endometrial carcinoma, prostate cancer, and VACTERL with hydrocephalus. [UniProt: P60484] Loss of the PTEN gene can be determined by various techniques, including FISH, and loss of the PTEN protein can be detected by immunohistochemistry techniques.

LP62864-1 FISH
FISH (fluorescence in situ hybridization) is a cytogenetic technique used to detect and localize the presence or absence of specific DNA sequences on chromosomes. FISH uses fluorescent probes that bind to only those parts of the chromosome with which they show a high degree of sequence similarity. Fluorescence microscopy can be used to find out where the fluorescent probe bound to the chromosomes. FISH is often used for finding specific features in DNA for use in genetic counseling, medicine, and species identification. FISH can also be used to detect and localize specific mRNAs within tissue samples. In this context, it can help define the spatial-temporal patterns of gene expression within cells and tissues.
