WebPTHrP appears to have a paracrine or autocrine role because serum levels are low except in a few clinical situations. Cord blood contains levels of PTHrP that are 3-fold higher than in serum from adults; it is produced by the fetal parathyroid glands and appears to be the main agent stimulating maternal-fetal calcium transfer.
WebApr 28, 2024 · Malignancy related hypercalcemia can be broadly divided into three categories: (1) humoral hypercalcemia of malignancy which is PTHrP mediated, (2) local osteolytic hypercalcemia, and (3) dysregulated calcitriol production [ 4 ]. See Table 1. Table 1 Hypercalcemia of malignancy. baterai nikon z50WebThe production of PTHrP is regulated by TGF-β released from the resorbing bone ( Kakonen et al., 2002; Yin et al., 1999) as described above. Factors which regulate PTHrP production are therefore important potential mediators of bone resorption. This was demonstrated by studies using PTHrP antibodies. baterai nokia n8WebVarious malignancies secrete PTHrP resulting in HHM. PTHrP production is most commonly seen in carcinomas of breast, lung (squamous), head and neck (squamous), kidney, bladder, cervix, uterus, and ovary.
