CTPS1 and triple-negative breast carcinoma: To further explore the molecular mechanism of CTPS1 in triple-negative breast cancer, we used JASPAR database (http://jaspar.genereg.net/) and PROMO software (http://alggen.lsi.upc.es/cgi-bin/promo_v3/promo/promoinit.cgi?dirDB=TF_8.3) to predict potential transcription factors of CTPS1 [16–18].
