Aim To investigate the promoting apoptosis effect of artesunate( ART) on human colon cancer Lovo cells and its mechanisms. Methods MTT assay was performed to determine the anti-proliferative effect of artesunate. Flow cytometry assay and electron micros-copy( EM) were used to evaluate the apoptotic effect of artesunate. Luciferase reporter assay was introduced to measure the activation of Wnt/β-catenin pathway. Western blot was used to detect the pathway-related protein levels of β-catenin, GSK-3β,c-Myc and apop-tosis-related protein level of casepase-3 . Results Compared with the control group, the inhibitory rate of cell proliferation at 72 h and 320 μmol·L-1 ART was (78. 99 ± 1. 95 )% ( F =898. 301, P =0. 000 ); the cell apoptotic rate at 24 h and 160 μmol · L-1 ART was(19. 00 ± 0. 05)% and morphological signs of cell apoptosis were found by EM;the transcriptional activi-ty of TCF4/LEF at 24 h and 160 μmol·L-1 ART was (0. 36 ± 0. 30)%(F =470. 954,P <0. 01); the ex-pressions of caspase-3 and GSK-3β were significantly increased, whileβ-catenin and c-Myc were significant-ly decreased when treated with different concentrations of ART for 48 h ( P <0. 01 ) . Conclusion ART may significantly inhibit proliferation and promote apoptosis of Lovo cells probably by inactivating Wnt/β-catenin pathway.

Aim To investigate the effect of artesunate on the invasion of human colon cancer Lovo cells and the possible mechanisms. Methods After Lovo cells were treated with different doses of artesunate(20,80, 160 μmol·L - 1 ), the soft agar colony formation test was adopted to observe the anchorage-independent pro-liferation of Lovo cells. Transwell assay was used to determine the effect of artesunate on the invasion abili-ty of Lovo cells. And the protein expressions of HMGB1 and MMP-2 were investigated by western blot. Results Artesunate could significantly inhibit both proliferation and invasion ability of Lovo cells in a dose-dependent manner(P < 0. 01). The experimental group treated with artesunate significantly down-regula-ted the protein expressions of HMGB1 and MMP-2 compared with control group(P < 0. 05). Conclusion Artesunate could inhibit the invasion of human colon cancer Lovo cells by down-regulating HMGB1 and MMP-2 expressions.

【Objective】 To investigate the impact of long non-coding RNA (lncRNA) FGD5-AS1 on the malignant biolo-goical behavior of bladder cancer (BC) cells by regulating micro RNA (miR)-129-5p/cyclin dependent kinase 6 (CDK6) axis. 【Methods】 Human BC cell line T24 was cultured from tumor tissue and paracancerous tissue of 105 patients with confirmed BC. The expressions of FGD5-AS1, miR-129-5p and CDK6 mRNA in tissue samples and T24 cells were detected with RT-qPCR. T24 cells were randomly divided into control group, si-NC group, si-FGD5-AS1 group, si-FGD5-AS1+inhibitor NC group and si-FGD5-AS1+miR-129-5p inhibitor group. The cell viability, migration, invasion andapoptosis were detected with CCK-8, Wound healing test, Transwell assay and flow cytometry, respectively. The expressions of Bax, Bcl-2, Caspase3 and CDK6 were detected with Western blot. The relationship between FGD5-AS1 and miR-129-5p, between miR-129-5p and CDK6 were verified with double luciferase reporter gene experiment. 【Results】 FGD5-AS1 and CDK6 mRNA were highly expressed in BC tissue, while miR-129-5p was lowly expressed (P<0.05). After FGD5-AS1 silencing, the expression of FGD5-AS1,A450 value, cell scratch healing rate, cell invasion number, and expressions of Bcl-2 and CDK6 were significantly lower, while the apoptosis rate and expressions of miR-129-5p, Bax and Caspase3 were significantly higher (P<0.05). Inhibition of miR-129-5p expression reversed the effects of FGD5-AS1 silencing on various indexes of BC cells (P<0.05). FGD5-AS1 negatively regulated the expression of miR-129-5p, and miR-129-5p negatively regulated the expression of CDK6. 【Conclusion】 Silencing FGD5-AS1 may inhibit the expression of CDK6 protein by up-regulating miR-129-5p, thus inhibiting the proliferation, migration and invasion of BC cells and promoting cell apoptosis.

OBJECTIVETo observe the effects of supernatants of normal skin keratinocytes(NK) and scar keratinocytes(SK) on proliferation and collagen synthesis of hypertrophic scar fibroblasts(HSFB).

METHODSThe supernatant, collected from cultured NK and SK, was added to the cultivated HSFB. The MTT-method, 3H-proline incorporation and radioimmunoassay were employed to measure the cell proliferation, collagen synthesis and secretion.

RESULTSNK supernatant could inhibit HSFB proliferation and increase the collagen synthesis, but inhibit collagen secretion, as compared with the control group. On the contrary, SK supernatant could increase collagen synthesis and secretion, which had little effects on HSFB proliferation.

CONCLUSIONKeratinocytes derived from normal skin and hypertrophic scar show different effects on hypertrophic scar fibroblasts.
