Figure 2From: Deregulated expression of circadian clock genes in gastric cancer Immunohistochemical analyses of eight circadian clock genes in gastric cancer (GC). A representative case of GC shows higher expression of PER2 in cancerous tissues compared with that in adjacent noncancerous tissues. Expression of PER1, PER3, CRY1, CRY2, CLOCK, CKIϵ, and BMAL1 does not differ between cancerous and noncancerous tissues from GC patients. Original magnification: 400 × .Back to article page
