Parathyroid hormone-related protein, bone metastases and hypercalcaemia of malignancy


Breast cancer patients frequently develop bone metastases. A newly discovered peptide, Parathyroid Hormone Related Protein (PTHrP), causes humoral hypercalcaemia of malignancy. We have studied whether production of this protein by breast cancers leads to the development of bone metastases or hypercalcaemia. PTHrP was produced by nearly 60% of early breast cancers and its production by the tumours was associated with malignant mammographic microcalcification, and the development of both bone metastases and hypercalcaemia. The hypercalcaemia associated with bone metastases has been shown to have a significant humoral component and measurement of plasma PTHrP in patients with hypercalcaemia is diagnostically useful. Potential mechanisms of preventing bone metastasis are discussed.

Solute carrier family's Profile



The solute carrier (SLC) group of membrane transport proteins include over 300 members organized into 52 families.  Most members of the SLC group are located in the cell membrane. The SLC gene nomenclature system was originally proposed by the HUGO Gene Nomenclature Committee (HGNC) and is the basis for the official HGNC names of the genes that encode these transporters. A more general transmembrane transporter classification can be found in TCDB database.
Solutes that are transported by the various SLC group members are extraordinarily diverse and include both charged and uncharged organic molecules as well as inorganic ions and the gas ammonia.
As is typical of integral membrane proteins, SLCs contain a number of hydrophobic transmembrane alpha helices connected to each other by hydrophilic intra- and extra-cellular loops. Depending on the SLC, these transporters are functional as either monomers or obligate homo- or hetero- oligomers.

Introduction of sex hormones


Have a common biosynthetic pathway hormones: cholesterol precursor, by reducing the side chain to produce the first 21 carbon pregnenolone or progesterone, then the side chain to 19 carbon Evolution androgen, and then through the A-ring 18 generated by the carbon aromatized estrogen. Metabolic inactivation of sex hormones are basically the same way, that the formation of glucuronic acid ester or sulfate conjugates, such as water-soluble strong in the liver, kidney and other metabolic organ, and then with the urine, or with the bile into the intestines from the feces .
Sex hormones in the mode of action at the molecular level, as with the other steroid hormones, in combination with a specific receptor protein into the cell, the formation of the hormone - receptor complex then binds to the nucleus, acts on the chromatin DNA affects the transcription activity of Consequently, new or increased existing protein biosynthesis, and thus the regulation of cell metabolism, growth or differentiation. Hormones for small molecules, with a fat-soluble, mainly by free diffusion (passive transport) into the cell, combined with cytoplasmic receptors, forming a hormone - cytoplasmic receptor complexes, conformational changes and heat shock protein from the solution obtained by entering ability of the nucleus, transfer into the cytoplasm by the nucleus, nuclear hormone receptor binding with the formation of the hormone - receptor complex nucleus to stimulate transcription of the DNA to produce a specific mRNA, and then into the cytoplasm, the ribosome formation of protein translation play biological effects.
