Knockdown of lymphoid enhancer factor 1 inhibits colon cancer progression in vitro and in vivo.

Expression of lymphoid enhancer factor 1 (LEF1) is frequently altered in different human cancers. This study aimed to assess LEF1 expression in colon cancer tissues and to explore changed phenotypes, gene expressions, and the possible mechanism after knocked down LEF1 expression in colon cancer cell lines. A total of 106 colon cancer and matched paratumorous normal tissues were used to assess LEF1 expression using immunohistochemistry and qRT-PCR.

[Therapeutic mechanism of bleomycin A5 on infancy hemangioma: an experimental study].

Objective: To investigate the therapeutic mechanism of Bleomycin A5 on infancy hemangioma.

Methods: After intralesional injection of Bleomycin A5 into the tumor of animal model of infancy hemangioma, the variation of tumor form was and the variation of tumor structure were observed using light microscope and electron microscope, the variation of tumor gene expression spectra was also tested by DNA microarray technique.

Results: After treatment, the tumor gradually shrunk, hardened, disappeared one month later.
