Fold-changes in the expression levels of cells upon different treatments

Analysed Genes	I	II	III	IV	S.E.M
TNF-like	1c	6.5a	3.1b	2.7b	0.23
IFN-γ	1c	4.4a	2.4b	2.3b	0.12
IL-1β	1c	5.3a	2.8b	2.5b	0.16

I: Untreated cells.

II: Heat-induced cells.

III: Heat-induced cells + PKC extract (125 μg /ml).

IV: Heat-induced cells + Silymarin (125 μg /ml).

The expression level of each studied genes was normalized to β-actin and GAPDH.

Means (n = 3) with different superscripts within row are significantly different (P < 0.05).
