Fig. 1From: Prognostic relevance of autophagy-related markers LC3, p62/sequestosome 1, Beclin-1 and ULK1 in colorectal cancer patients with respect to KRAS mutational statusp62 immunohistochemistry. Examples of p62 immunostaining in colorectal cancers. The upper row shows three tumours with strong cytoplasmic immunostaining and the lower row demonstrates three tumours with negative p62 staining (×400 magnification). Note the positively stained of stromal cells/macrophages, which can be used as internal controlsBack to article page
