PTCSC3, shorted for papillary thyroid carcinoma susceptibility candidate 3, is involved in Papillary thyroid carcinoma.
PTCSC3: Papillary thyroid carcinoma susceptibility candidate 3 (HGNC nomenclature)
LncBook ID: HSALNT0209589
PTCSC3 consists of 4 exons with a total length of 1152 bp, located on a human chromosome 14q13.3 and spanning more than 40 kb of genomic region in a linkage disequilibrium block with a GWAS-derived SNP (rs944289) .
PTCSC3 regulate the expression of genes involved in DNA replication, recombination, repair, cellular movement, tumor morphology, and cell death especially the genes that are important for papillary thyroid carcinoma (PTC) development and progression such as S100A4, RHOB, MOAP1, AKT, CTSA, MECP2, FLNA, C19orf33, GDF15, and others .
PTCSC3 expression is highly thyroid specific suggests that it is involved in thyroid function . overexpression of PTCSC3 significantly downregulates miR-574-5p expression in thyroid cancer cells that are of papillary, follicular and anaplastic origin .
PTCSC3 expression is significantly down-regulated in tumor compared with unaffected thyroid tissue, and the risk allele is associated with significantly stronger suppression of PTCSC3. The restoration of PTCSC3 expression in PTC cell line affects genes involved in thyroid tumorigenesis and inhibits cell growth .
rs944289 predisposes to PTC by dysregulating the expression of PTCSC3, which acts as a tumor suppressor.
PTCSC3 is almost uniquely expressed in thyroid tissue with very low expression additionally in kidney tissue.
The cDNA of PTCSC3 was amplified by PCR,
C/EBPα and C/EBPβ regulate the transcriptional activity of the PTCSC3 promoter .
