PRKCQ and triple-negative breast carcinoma: LncRNA PRKCQ-AS1, previously associated with colorectal cancer cells progression and migration, and paclitaxel resistance in triple negative breast cancer cells [40, 41], was found to be upregulated in 30 tamoxifen-resistant samples of bulk RNA-seq. Moreover, PRKCQ-AS1 expression was higher in CAFs-derived exosomes than in NF-derived exosomes.
