BRD3OS and skin squamous cell carcinoma: Paraffin-embedded formalin-fixed TMA samples containing normal skin (n = 24), premalignant AK (n = 67), precancerous cSCCIS (n = 60), UV-induced primary non-metastatic invasive cSCC (n = 119), primary metastatic cSCC (n = 76) and cSCC metastases (n = 8) were analyzed with RNA-ISH for the expression of BRD3OS (LINC00094) in cSCC carcinogenesis in vivo.
