Table 2 Expression of detectable levels (abundance ≥ 50) of MPL , EPOR , ERBB2, and IGF1R mRNA in normal tissue and tumor samples by qRT-PCR

From: Low or undetectable TPO receptor expression in malignant tissue and cell lines derived from breast, lung, and ovarian tumors

  Breast normal N = 7 n (%) Breast tumor N = 40 n (%) Lung normal N = 8 n (%) Lung tumor N = 40 n (%) Ovarian normal N = 7 n (%) Ovarian tumor N = 41 n (%)
MPL 1 (14) 1 (3) 1 (13) 1 (3) 3 (43) 3 (7)
EPOR 7 (100) 32 (80) 8 (100) 28 (70) 7 (100) 41 (100)
ERBB2 4 (57) 33 (83) 8 (100) 22 (55) 7 (100) 39 (95)
IGF1R 2 (29) 15 (38) 1 (13) 2 (5) 0 (0) 7 (17)
  1. Quantitative reverse transcription-polymerase chain reaction was used to measure abundance of these genes. Data are represented as number of samples with detectable expression and percent of the samples in parenthesis.
