Figure Lengend Snippet: Hsp70s Regulate Circadian Rhythm under various conditions. A Immunoprecipitation assays were performed to compare the interaction strength between wild-type PER and Hsp70Ba under various temperature conditions. Western blot analysis was performed with mouse anti-V5 (ABclonal, Cat#AE017), mouse anti-HA (ABclonal, Cat#AE008) antibodies and rabbit anti-Actin (ABclonal, #AC026). B Statistics of ( A ). N = 3. Statistical differences were assessed using one-way ANOVAs and post-hoc Tukey tests (P < 0.05). C Representative double plot actograms showing average locomotor activity for the respective genotypes under heat shock conditions. White background indicates light, and black indicates darkness. D Analysis of circadian rhythm persistence in Hsp70 mutants and w 1118 controls following heat shock. P-values from two-sided Fisher’s exact test are indicated (***P < 0.001)

Article Snippet: For drug treatment, 100 μM of the Hsp70 inhibitor VER-155,008 (Target Mol, #T7010) was dissolved in the media.

Figure Lengend Snippet: Hsp70 Protein Interacts with PER, Affecting PER Phosphorylation and Cellular Localization. A Relative per expression at different time points in Hsp70 mutants and the control group. B Antibody specificity evaluation in western blot analysis for PER protein. C PER protein detection by western blots at ZT3, ZT9, ZT15, and ZT21. B - C Western blot analysis was performed with anti-PER (a gift from Dr. Jeffrey Price’s laboratory at the University of Missouri-Kansas City, U. S.) and mouse anti-β-Tubulin (ABclonal, Cat#AC021). D Quantification of results in ( C ). N = 5. Statistical differences were measured using an unpaired Student’s t-test. **P < 0.01, ***P < 0.001. E Statistics of the cellular localization of PER in s-LNvs and l-LNvs clusters of clock neurons in indicated genotypes. C represents cytoplasm, and N represents nucleus. F Immunoprecipitation experiments to detect the interaction between PER, TIM, and Hsp70s. Western blot analysis was performed with mouse anti-V5 (ABclonal, Cat#AE017), mouse anti-HA (ABclonal, Cat#AE008) antibodies and mouse anti-β-Tubulin (ABclonal, Cat#AC021). Samples were prepared in S2 cells, with β-tubulin used as an internal control. G Calculation of average TIM binding by PER molecule. N = 3. Significance of differences was determined using one-way ANOVAs and post-hoc Tukey tests. H Immunoprecipitation experiments to detect the interaction between PER and Hsp70s in tim 01 and w 1118 controls. Western blot analysis was performed with anti-PER (a gift from Dr. Jeffrey Price’s laboratory at the University of Missouri-Kansas City, U. S.) and anti-β-Tubulin (ABclonal, Cat#AC021). β-tubulin was used as an internal control. ( I ) Calculation of average Hsp70 binding by PER molecule. N = 5. The t-test was used to calculate the significance of differences. **P < 0.01
