Table I.

GCS expression in human breast cancer.

Tumors	GCS mRNA levels (mean ± SD, copies)	Overexpressed/total cases (>307 copies)
Stage I	243±56	1/3
Stage II	222±41	3/6
Stage III	325±48	5/7
LN-negative	138±12	2/8
LN-positive	408±37^a	7/8
ER-negative	49±8	0/7
ER-positive	367±38^a	7/9

The value of mean ± 2SD in normal breast tissues (307 copies) was used to evaluate the overexpression of GCS mRNA in specimens. LN, lymph node; ER, estrogen receptor.

p<0.001 compared with LN-negative or ER-negative.
