Haploinsufficiency in the prometastasis Kiss1 receptor Gpr54 delays breast tumor initiation, progression, and lung metastasis.

Activation of KISS1 receptor (KISS1R or GPR54) by its ligands (Kisspeptins) regulates a diverse function both in normal physiology and pathophysiology. In cancer, KISS1R has been implicated in tumor angiogenesis and metastasis, but a broader evaluation of KISS1R in tumorigenesis and tumor progression is yet to be conducted. In this study, we used mouse models of Kiss1r gene knockout and mouse m...

The Role of Matrix Metalloproteinase-3 Functional 5A/6A Promoter Polymorphism in Tumor Cell Progression and Metastasis of Breast Cancer

In the human genome, chromosome 11 contains a cluster of matrix metalloproteinase (MMP) genes. Single nucleotide polymorphisms in the promoter region of MMP genes are important for MMP expression. A common adenine deletion polymorphism (5A) at position -1171 of the MMP-3 gene promoter (5´-AAAAAACCAT-3´ change to 5´-AAAAACCAT-3´) facilitates transcriptional factor binding and MMP-3 promoter acti...

PTHrP drives breast tumor initiation, progression, and metastasis in mice and is a potential therapy target.

Parathyroid hormone-related protein (PTHrP) is a secreted factor expressed in almost all normal fetal and adult tissues. It is involved in a wide range of developmental and physiological processes, including serum calcium regulation. PTHrP is also associated with the progression of skeletal metastases, and its dysregulated expression in advanced cancers causes malignancy-associated hypercalcemi...

Kisspeptin/Gpr54-independent GnRH activity in Kiss1 and Gpr54 mutant mice

The kisspeptin/Gpr54 signaling pathway plays a critical role in reproduction by stimulating the secretion of GnRH, yet mice carrying mutations in Kiss1 (which encodes kisspeptin) or Gpr54 exhibit partial sexual maturation. For instance, a proportion of female Kiss1−/− and Gpr54−/− mice exhibit vaginal oestrus, and some male Kiss1−/− and Gpr54−/− mice exhibit spermatogenesis. To characterise thi...
