 A Corrigendum on Exercise and/or Cold Exposure Alters the Gene Expression Profile in the Fat Body and Changes the Heart Function in Drosophila By Huang T, Jian X, Liu J, Zheng L, Li FQ, Meng D, Wang T, Zhang S, Liu Y, Guan Z and Feng J (2022) Front.

In the original article, there was a mistake in Figure 4 as originally published. Figure 4 was incomplete and omitted a set of results. The corrected Figure 4 appears here.

In the Results, subsection Exercise and/or Cold Exposure Reduced the Amount of Fat in Fruit Flies as originally published, the following sentence contained the wrong table citation: “According to the multi-factor analysis of variance (ANOVA) of triacylglycerol (TAG) levels ( Table 3 ), feeding patterns and interventions exert major effects on TAG levels and have no interaction.” The correct citation is: “According to the multi-factor analysis of variance (ANOVA) of triacylglycerol (TAG) levels ( Table 1 ), feeding patterns and interventions exert major effects on TAG levels and have no interaction.”

In the Discussion (seventh paragraph) as originally published, the following sentence contained the wrong figure citation: “In addition, the locomotor ability of fruit flies also significantly improved ( Figure 6 )” The correct citation is: “In addition, the locomotor ability of fruit flies also significantly improved ( Figure 5 ).”

Flies’ locomotor ability under different interventions. *P < 0.05, **P < 0.01, ***P < 0.001.

Heart function in HFD and NFD fruit flies. *P < 0.05, **P < 0.01, ***P < 0.001, ns P > 0.05.

In the Discussion (eighth paragraph) as originally published, the following sentence contained the wrong figure citation: “It can be seen from Figure 7 that cold environments seem to exert no effects on HFD fruit flies’ locomotor capacity. The HFD flies had improved locomotor capacity after losing weight.” The correct citation is: “It can be seen from Figure 5 that cold environments seem to exert no effects on HFD fruit flies’ locomotor capacity. The HFD flies had improved locomotor capacity after losing weight.”

Changes in heart function of NFD fruit flies. *P < 0.05, **P < 0.01, ***P < 0.001.

In the Methods, subsection qRT-PCR as originally published, the following sentence incorrectly stated that the expression-analysis primers were shown in Table 3 : “ Table 3 shows the primers used for expression analysis”. The sentence should read “Primers used for expression analysis were as follows:”.
