Additional file 3: Figure S1: Phospho-LYRIC expression in the primary and metastatic tumor tissue of NPC patient. 31 primary NPC tissues were from the nasopharyngeal biopsy tissues of NPC patients, and 27 metastatic tumor tissues were from the cervical lymph metastatic node. The primary NPC and metastatic tumor samples were embedded, and 4 ��m-thick tissue sections were deparaffinized in xylene, rehydrated in a graded alcohol series. Phospho-LYRIC was detected in these sections using immunohistochemistry. a, Primary NPC paraffin sections were stained with antibody against phospho-LYRIC S568; b, Metastatic tumor tissues were stained with antibody against phospho-LYRIC S568; c, Primary NPC tissues were stained with hematoxylin and eosin; d, Metastatic tumor tissues were stained with hematoxylin and eosin. Arrow, positive cells. Original magnification, �� 400. Scale bar, 5��m. H & E, hematoxylin and eosin. (DOC 330 KB)
