Palm kernel cake extract exerts hepatoprotective activity in heat-induced oxidative stress in chicken hepatocytes

Table 4 Fold-changes in the expression levels of cells upon different treatments

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