Since the regression of s.c. implanted lung carcinoma tumors in Cav-2 KO mice started as early as after day 8, at which the tumor volume reached its maximum, these early stage tumors extracted at day 8 after LLC cell implantation became critical for our mechanistic studies examining the immune cell types using a multi-color flow cytometry approach. The gene discussed is CAV2; the disease is lung carcinoma.
