The data generated here in relates to the research article “CaV1.3 enhanced store operated calcium promotes resistance to androgen deprivation in prostate cancer”. A model of prostate cancer (PCa) progression to castration resistance was employed, with untreated androgen sensitive LNCaP cell line alongside two androgen deprived (bicalutamide) sublines, either 10 days (LNCaP-ADT) or 2 years (LNCaP-ABL) treatment, in addition to androgen insensitive PC3. With this PCa model, qPCR was used to examined fold change in markers linked to androgen resistance, androgen receptor (AR) and neuron specific enolase (NSE), observing an increase under androgen deprivation. In addition, the gene expression of a range of calcium channels was measured, with only the L-type Voltage gated calcium channel, CACNA1D, demonstrating an increase during androgen deprivation. With CACNA1D knockdown the channel was found not to influence the gene expression of calcium channels, ORAI1 and STIM1. The calcium channel blocker (CCB), nifedipine, was employed to determine the impact of CaV1.3 on the observed store release and calcium entry measured via Fura-2AM ratiometric dye in our outlined PCa model. In both the presence and absence of androgen deprivation, nifedipine was found to have no impact on store release induced by thapsigargin (Tg) in 0mM Ca2+ nor store operated calcium entry (SOCE) following the addition of 2mM Ca2+. However, CACNA1D siRNA knockdown was able to reduce SOCE in PC3 cells. The effect of nifedipine on CaV1.3 in PCa biology was measured through cell proliferation assay, with no observed change in the presence of CCB. While siCACNA1D reduced PC3 cell proliferation. This data can be reused to inform new studies investigating altered calcium handling in androgen resistant prostate cancer. It provides insight into the mechanism of CaV1.3 and its functional properties in altered calcium in cancer, which can be of use to researchers investigating this channel in disease. Furthermore, it could be helpful in interpreting studies investigating CCB's as a therapeutic and in the development of future drugs targeting CaV1.3.
