Figure Lengend Snippet: ANKRD1 knockdown reduces metastasis efficiency of breast cancer cells in two in vivo metastasis models. ( A , B ) Representative bioluminescence (BLI) images of animals showing primary tumors (PT) at day 21, derived from orthotopic injections of LM-2 vector control (vector) and LM-2 ANKRD1 knockdown (LM-2 sh14) cells into the mammary fat pad. On day 21 after orthotopic injection into the mammary fat pad, tumor growth at the injection site and GFP was detected by IVIS and quantified based on radiant efficiency, comparing vector and LM-2 sh14 groups (day 21, n = 10 per group). ( C ) Comparison of the size of primary tumors from vector and LM-2 sh14 groups after removing the primary tumor. ( D ) Quantitation of tumor volume (cm 3 ) comparing control and LM-2 sh14 groups. The results show no significant change in tumor volume and tumorigenesis in the LM-2 sh14 cell group compared to the vector. Data presented as mean ± SD. ( E ) Radiant efficiency of the lung and liver comparing vector and LM-2 sh14 groups and ex vivo GFP signals, detected using IVIS. ( F , G ) Representative BLI images of animals on the first day of tail vein injection and quantitation of radiant efficiency in mice (day 1, n = 10 per group). ( H ) Liver metastasis with control and LM-2 sh14 cells. The results show increased metastasis of cancer cells in control compared to LM-2 sh14 group. ( I , J ) H&E staining of liver tissue from tail-vein-injected mice; red circles show the cancerous lesions in the tissues, which are increased in the control group compared to the LM-2 sh14 group. LM-2 Vector (control): LM-2 with empty vector; LM-2 sh14: LM-2-ANKRD1 knockdown with sh14. Ten NOD.SCID mice were used for each set, and all experiments were performed in triplicate.
Article Snippet: A human breast cancer tissue array containing 100 cancer cases of different grades was purchased (BR10011, US Biomax, Rockville, MD, USA), and mouse organs were collected and maintained in 4% paraformaldehyde solution and used to detect ANKRD1 expression.
