Systemic surfaceome profiling identifies target antigens for immune-based therapy in subtypes of advanced prostate cancer.

abstract：:The influx of Ca2+ ions controls many important processes in excitable cells, including the regulation of the gating of Ca(2+)-activated K+ channels (the current IK[Ca]). Various IK[Ca] channels contribute to the regulation of the action-potential waveform, the repetitive discharge of spikes, and the secretion of neur...
