Concentration of endogenous estrogens and estrogen metabolites in the NCI-60 human tumor cell lines

Table 2 Means and standard deviations of total estrogen levels measured in cell types within the NCI-60 cell line panel

	Mean	SD	Mean (-high/low)*	SD (-high/low)*
Breast	83.18	21.70	88.00	11.78
CNS	90.05	75.07	67.77	31.31
Colon	58.19	82.12	33.21	26.64
Leukemia	187.48	372.4	42.71	28.67
Melanoma	94.23	67.69	88.75	55.49
NSCL	86.69	71.98	77.13	49.25
Ovarian	96.33	54.00	93.49	46.84
Prostate	46.59	10.42	NA	NA
Renal	46.57	25.49	42.20	10.44

Mean and standard deviation (SD) are presented for all values within specific cell types and for values after eliminating cell lines with the highest and lowest total estrogen levels. CNS, central nervous system; NSCLC, non-small cell lung carcinoma. *Mean and standard deviation calculated after removing cell lines containing highest and lowest total measured estrogen levels. NA, only two prostate cell lines were included in NCI-60 cell lines analyzed.
