Table 1. GRIM-1 expression levels in normal and tumor specimens analyzed by immunohistochemistry.

Level@ →	Normal						Tumor						Loss (%)
	+	++	+++	++++	+++++	Total	+	++	+++	++++	+++++	Total
Prostate	4	5	7	14	8	38	21	17	8			46
Prostate (paired)	3	3	4	8	6	24	7	11	6			24	75

@Expression level graded on an arbitrary scale (%) using signal ratio of GRIM-1 to DAPI.

+ (0–20) – Severe loss, ++ (21–40) – Significant loss, +++ (41–60) – Moderate loss, ++++ (61–80) – Slight loss, +++++ (81–100) – No loss.
