KITLG


Also found in: Dictionary.

KITLG

A gene on chromosome 12q22 that encodes KIT tyrosine kinase receptor ligand, which plays a key role in regulating cellular activities (such as: cell survival and proliferation; haematopoiesis; stem cell maintenance; gametogenesis; mast cell development; migration and function; and in melanogenesis) by activating multiple signalling pathways.

Molecular pathology
KITLG mutations cause familial progressive hyperpigmentation.

The 4 major GWAS performed to date have demonstrated the association of testicular cancers with genes such as KITLG, SPRY4, BAK1, TERT, ATF1IP, and DMRT1, which are generally recognized as important in cancer pathogenesis (6,7,21,22).
As PGCs migrate from the midgut to the GR, somatic KIT ligand (KITLG) secretion induces rapid PGC proliferation and suppresses apoptotic pathways used to clear ectopic cells [56].
Conclusion: In conclusion, the results revealed that niche cells respond to SSCs removal by upregulation of GDNF and FGF2, and downregulation of KITLG in order to stimulate self-renewal and arrest differentiation.
This change affects how much KITLG is expressed in the hair follicles without changing how it's expressed in the rest of the body.
They found that KITLG activation by p53 is crucial for cancer processes, including cell proliferation, and found it was much more common in Caucasians than Africans, explaining why testicular cancer is more common among the latter.

Men with two copies of "common" KITLG are 4.5 times more likely to suffer testicular cancer than men with two copies of a rarer version.

The relative mRNA expression levels of StAR, CYP11a, AMH, and Kitlg were calculated by setting the mRNAs levels of [beta]-actin as one.
It then must bind a specific sequence of DNA located in a gene called the KIT ligand oncogene (KITLG), which stimulates melanocyte production, causing the skin to tan.
Conversely, KITLG was found to be upregulated in HTB82 holoclones, but no differences were observed in CW9019 for this marker (Figure 6).
In other cattle breeds, there are many SNPs reported in color related genes such as TYP, TYRP1, ASIP, DCT, melanophilin (MLPH), c-Kit (KIT), cKit ligand (KITLG), which caused phenotypic variations in hair follicles (Van den Bossche et al., 2012).
