Abstract

Objective:

To investigate the effect of capsaicin on proliferation in human hepatoma SMMC-7721 cells and its possible molecular mechanism.

Method:

Capsaicin (50

100

150

200

250

300 μmol·L

-1

) groups and blank group were set up. The cell viability was detected by cell counting kit-8 (CCK-8) assay after SMMC-7721 cells were treated with capsaicin (50

100

150

200

250

300 μmol·L

-1

) for 24

72 h. The morphological changes were observed under an inverted microscope after SMMC-7721 cells were treated with capsaicin (150

200

250 μmol·L

-1

) for 24 h. The mRNA expression levels of high mobility group box 1 (HMGB1) and interleukin-6(IL-6) were measured by Real-time PCR after SMMC-7721 cells were treated with capsaicin (150

200

250 μmol·L

-1

) for 24 h. The levels of HMGB1 and IL-6 in cell culture supernatant were detected by enzyme-linked immunosorbent assay(ELISA) after SMMC-7721 cells were treated with capsaicin (150

200

250 μmol·L

-1

) for 24 h.

Result:

Compared with the blank group

there was no significant difference between 50 and 100 μmol·L

-1

capsaicin groups treated for 24

72 h; after treated with the other concentrations of capsaicin (150

200

250

300 μmol·L

-1

) at different time points

the proliferation inhibition rate was statistically significant (

0.05)

with significant concentration and time-dependent effect; compared with the blank group

capsaicin (150

200

250 μmol·L

-1

) groups showed different degrees of morphological changes in SMMC-7721 cells

which became round and wrinkled

with a poor attachment and more exfoliation; compared with the blank group

the mRNA expressions of HMGB1 and IL-6 in SMMC-7721 cells of capsaicin (150

200

250 μmol·L

-1

) groups were significantly down-regulated (

0.05)

and the secretions of HMGB1 and IL-6 were significantly decreased in the supernatant (

0.05).

Conclusion:

Capsaicin inhibits cell proliferation of SMMC-7721 cells

and the possible mechanism may be related to the down-regulation of HMGB1 and IL-6 at the mRNA and protein levels.
