Figure Legend Snippet: Panels A and B: Food consumed daily in 4 groups of female (panel A) and male (panel B) animals from P38-43. The average daily food intake (kcal) relative to P40 was calculated as the food intake during each of the day divided by the total food intake of the animal on P40. Exercise alone reduces animal’s food intake in both females and males from P41 to P43. ABA females increased food intake on day 3 of food restriction (P43) compared to the first 24 hours of food restriction (P41), while no change of daily food intake was detected among ABA males during the three days of food restriction.
Techniques Used:
Figure Legend Snippet: Panel A: A schematic of weight changes measured in relation to FAA. Panel B: For both female ABA and EX groups, the initial weight change from 1–7 pm on P41 are not correlated with the wheel activities during 1–7 pm on P42. Panel C: The weight changes within the initial 6 hr of food restriction (1–7 pm) correlates positively with the food anticipatory activity (1–7 pm) of ABA males on the second day of food restriction (FR2), but not for EX males on the corresponding day. Panel D: For both female ABA and EX groups, weight changes from P41-42 (7–7 pm) are not correlated the wheel activities during 1–7 pm on P43 (FAA on FR3). Panel E: Weight changes from P41-42 (7–7 pm) correlate positively with the food anticipatory activity (1–7 pm) of ABA males on the third day of food restriction (FAA on FR3), but not for EX males on the corresponding day. Regression lines indicate a significant correlation with p < .05. Dash regression lines indicate a marginal significant correlation with p = .057. Grey arrows indicate the mean value of each group.

Figure Legend Snippet: Panels A–B, D–F: The electron micrographs show the range of subcellular locations where a4-immunoreactivity can be found. α4-subunit immunoreactivity was detected by the presence of SIG (silver-intensified gold) labels, which occurred on the plasma membrane (black short arrows) and intracellularly (white arrows) within dendritic shafts (Panels A, B) and spines (Panels D, E, F). T=terminal; Sp = dendritic spine. Plasmalemmal SIGs on dendritic shafts are near terminals forming symmetric, presumably inhibitory, synapses. Synapses associated with dendritic spines are asymmetric, based on the presence of thick postsynaptic densities, and presumably excitatory. These micrographs were taken from tissue of a CON female (Panel A), a CON male (Panel B), and females that underwent ABA (Panels D, E, F). Asterisks in panel A indicate the surface-most regions of vibratome sections, where transitions to no-tissue zones are apparent. Calibration bar equals 1 μm for panels A, D, E and F and equals 640 nm for panel B. Panel C: Group comparison of the density of α4-subunit immunoreactivity at dendritic shafts. ABA did not evoke a statistically significant difference from the CON in the plasmalemmal (upper panel), intracellular (middle panel), or total (plasmalemmal plus intracellular) labeling (lower panel) for females or males. Panel G: Group comparison of α4-subunit immunoreactivity at the plasma membrane of dendritic spines, at intracellular sites of dendritic spines, and generally within dendritic spines (plasmalemmal plus intracellular). ABA did not evoke a statistically significant difference from CONs in membranous labeling (upper panel) of either sex. For females, α4-subunit immunoreactivity was significantly increased at intracellular sites of dendritic spines (middle panel) and generally in association with dendritic spines (plasma membrane plus intracellular components) (lower panel), relative to CON tissue. Such a difference was not observed for the ABA males. * indicates p < .05.

Figure Legend Snippet: Panels A and B: Food restriction (FR)-induced increase in wheel running activity was calculated as the average running activity during the three food-restricted days minus the average wheel running activity during the three days preceding food restriction. This value is negatively correlated with the density of α4-subunits at the plasma membrane of ABA females (panel A), but not of ABA males (panel E). Females with the highest levels of α4-subunit immunoreactivity showed the least amount of food restriction-induced increase in wheel running. Panels B – D: For ABA females, the average running activity during the three food-restricted days (panel B), the average running activity during the last two day of food restriction (FR2 + FR3, panel C), and the wheel running activity on the last day (FR3, panel D), are negatively correlated with the density of α4-subunits at the plasma membrane. Females with the highest levels of α4-subunit immunoreactivity showed the least amount of wheel running activity during these food-restricted periods (panels B, C and D). Panels F–H: On the other hand, α4-subunit immunoreactivity of ABA males did not correlate with their wheel running during the three food-restricted days (panels F). Males with the highest levels of α4-subunit immunoreactivity showed the highest amount of wheel running activity during the last two days of food restriction (panel G–H). Regression lines indicate a significant correlation with p < .05. Dashed regression lines indicate a marginal significant correlation with p ≦ .1.

Figure Legend Snippet: Panels A and E: Body weight loss after three days of food restriction (FR) is negatively correlated with α4-subunit labeling at the plasma membrane of ABA females (panel A) but not of ABA males (panel E). Females with the highest levels of α4-subunit immunoreactivity show the least amount of weight loss during the food-restricted period. Panels B and F: Wheel running activity during the first day of food restriction is negatively correlated with α4-subunit labeling at the plasma membrane of ABA females (panel B) but not of ABA males (panel F). Females with the highest levels of α4-subunit immunoreactivity show the least amount of wheel running activity during the first day of food restriction. Panels C–D, G–H: Female and male hippocampi differ in the subcellular compartment exhibiting correlation between α4-subunit immunoreactivity and wheel running activity. Food restriction-induced increase in wheel running activity during the food access period was calculated by the running activity during the food-access period on P41 minus the wheel running activity during 7–9 pm of the evening preceding food restriction. This value is negatively correlated with α4-subunits’ plasma membrane labeling of ABA females (panel C), but not of ABA males (panel G). Females with the highest levels of α4-subunit immunoreactivity show the least amount of food restriction-induced increase in wheel running during the food-restricted days. Food restriction-induced FAA during food-restricted days was calculated as the difference between FAA during P42 and the wheel running activity during the hours of 1–7 pm on the day preceding food restriction. This value is positively correlated with the level of α4-subunits at intracellular locations of ABA males (panel H), but not of ABA females (panel D). Males with the highest levels of α4-subunit immunoreactivity show the highest amount of food restriction-induced FAA during food-restricted days. Regression lines indicate a significant correlation with p < .05.

Figure Legend Snippet: Panels A and B: Daily wheel activity, measured as the distance run on the wheel, of α4-GABAAR KO (α4 −/−) and their wild-type (WT) littermate (α4 +/+) female (panel A) and male (panel B) animals one-day preceding and following food restriction. Food restriction significantly increased wheel running activity of both female and male KO animals. The extent of increase of running induced by food restriction is greater for KO animals, compared to their WT littermates, especially among the female cohorts. The dashed bars represent baseline wheel activity of WT and KO animals (P40). The bars with no pattern represent wheel activity measured on the first day of food restriction phase for WT and KO animals (P41). * indicates p < .05. “ns” indicates no significant difference.
