Tool Details

  • Tool name: R-3327-3.1 cell line
  • Tool type: Cell Lines
  • Disease: Cancer
  • Model: Cancer Model
  • Description: AT-3 originates from the spontaneous tumor (R3327) of the prostate identified by W.F. Dunning in a 22 month-old inbred Copenhagen male rat in 1961. R3327 has been maintained by continuous serial passage in rats for many years. Following subcutaneous transplantation in syngeneic male rats, AT-3 forms solid sheets of malignant cells with no indication of glandular function. AT-3.1 tumors grow continuously with a doubling time of 1.5-1.8 days regardless of the androgen status of the host and exhibit a high rate of metastasis to the lung and lymph nodes (>75% of rats inoculated sub-cutaneously develop distant metastases). The AT-3 subline can be used to study the effects of various types of cancer therapies on prostate cells. Together AT-3 and the related Dunning sublines also provide a valuable model for studying prostate malignancies both in vitro and in vivo.
