AURKA and small cell carcinoma: We observed that expression of a majority of the HOTPAM9 kinase expression was significantly impacted when HOXB13 expression was silenced with HOXB13 siRNAs in C4-2B and LNCaP and in VCaP cells to a certain extent (BUB1, NEK2, and AURKA) growing in charcoal stripped media, but not in the small cell carcinoma cell line PC3 (Fig. 2e,f, Supplementary Fig. 2e).
