Figure 3. SNHG1 promotes breast cancer cell metastasis and proliferation in vivo. (A) Representative images of cancer metastasis in SCID mice monitored at indicated time points using in-vivo imaging system. (B) Representative images of excised lungs from SCID mice of different groups (top). Representative images of HE staining of lung sections (bottom). Scale bar=400μm. (C) Statistics data of lung nodules of SCID mice (n=5 each group). **p<0.01 compared with NC control. (D) Representative images of excised tumors from nude mice. Scale bar=1cm. (E) The mass of xenograft tumors excised from nude mice (n=5 each group). **p<0.01 compared with NC control.
