C/EBPβ Isoforms Expression in the Rat Brain during the Estrous Cycle

Table 1

The LAP/LIP ratio in the different brain areas throughout the estrous cycle. The ratio was expressed as the average of both LAP1 and LAP2 isoforms content to that of the LIP isoform. The data represent the ratios in each estrous cycle phase (metestrus, diestrus, proestrus, and estrus) in the different brain areas (cerebellum, prefrontal cortex, and hippocampus) with their respective standard deviation (SD).

	Cerebellum	Prefrontal cortex	Hippocampus
	Ratio ± SD	Ratio ± SD	Ratio ± SD
Metestrus	1.9 ± 0.62	2.7 ± 0.54	8.1 ± 1.75
Diestrus	2.4 ± 0.71	3.0 ± 0.95	7.3 ± 2.90
Proestrus	3.6 ± 0.83	1.7 ± 0.35	6.6 ± 1.52
Estrus	4.4 ± 0.91	2.2 ± 0.34	4.8 ± 1.27

metestrus versus estrus, diestrus versus proestrus.
