Figure Lengend Snippet: Fig. 1. Experimental protocol. All trained animals carried out 4 weeks of training, 5 times per week either in MICT or HIIT. All animals performed both incremental test and grip strength at PRE, 2W and POST, while they only performed adhesive removal test and the novel object recognition test at the end of the training (in POST). During the incremental test, blood lactate was collected at every level to determine the SLT. At the end of the protocol (48 h after the last incremental test) both hippocampi and cortices were removed to perform Western blot and ELISA measurements.

Article Snippet: Quantification of pro and mature BDNF standard and cortical samples was respectively performed with proBDNF Rapid ELISA Kit (Biosensis®, BEK-2217-2P – sandwich ELISA–Thebarton, SA, Australia) and mBDNF Rapid ELISA Kit Kit (Biosensis®, BEK-2211-1P/2P–sandwich ELISA–Thebarton, SA, Australia) in the concentrated solutions following the manufacturer’s protocol.

Figure Lengend Snippet: Fig. 4. Effect of MICT and HIIT programs on cortical protein levels. (a) Level of cortical mBDNF (n = 19) measured by ELISA (in pg/ml-1) in MICT, HIIT and Control groups at POST training. Level of cortical (b) TrkB (n = 20), (c) pTrkB (n = 20), (d), p757NTR (n = 19), (e) NKCC1/KCC2 ratio (n = 19), (f) KCC2 (n = 18) and (g) CTSB (n = 20) in MICT, HIIT and Control groups at POST training. Protein level measured by Western blot, was calculated as the ratio of the protein of interest divided by the protein of normalization relative to the control. The normalization protein was the α-tubulin for all the molecules except for the KCC2 which was β3-tubulin. Pictures of Western blot membranes are shown below each graph. Dashed lines were added to separate the groups. Note that the α-tubulin used for TrkB (c) was the same used for pTrkB (d), as membranes were stripped between these two quantifications. The samples derived from the same experiment and that gels/ blots were systematically processed in parallel the same day (2 gels per protein to reach a sufficient number of samples). *Significant differences in protein levels between groups. Data is expressed in mean ± SD (a–f) and in median (min to max) (g).

Figure Lengend Snippet: Fig. 5. Effect of MICT and HIIT programs on hippocampal protein levels. (a) Level of hippocampal IGF- 1(n = 21) measured by ELISA in MICT, HIIT and Control groups at POST training. Level of hippocampal (b) IGFB-2 (n = 21), (c) p75NTR (n = 22), (d) TrkB (n = 21), (e) CTSB (n = 22), (f) NKCC1 (n = 21), (g) KCC2 (n = 20), and (h) the NKCC1/KCC2 ratio (n = 18) measured by Western blot in MICT, HIIT and Control groups at POST. Protein level was calculated as the ratio of the protein of interest divided by the protein of normalization relative to the control. The normalization protein was the α-tubulin for all the molecules except for the KCC2 which was β3-tubulin. Pictures of the Western blot membranes are shown below each graph. Dashed lines were added to separate the groups. Note that the α-tubulin used for p75NTR (c) was the same used for NKCC1 (f) as their molecular weight are different, the quantification of both was conducted on the same membranes. The samples derived from the same experiment and that gels/blots were processed in parallel the same day (2 gels per protein to reach a sufficient number of samples). *Significant differences in protein levels between groups. All data is expressed in mean ± SD.
