PFKFB3 and F2,6BP levels are low in HD patients impacting mitochondrial health. A , Western blot showing the relative levels of PFKFB3 in the cytosolic (CE), nuclear (NE) and mitochondrial (ME) extract of HEK293 cells. GAPDH: cytosolic loading control; HDAC2: nuclear loading control. COX4: mitochondrial loading control. B , Western blot showing the relative levels of PNKP and PFKFB3 in the mitochondrial extract of Q-7 and Q-111 cells. COX4: mitochondrial loading control. Lower panel : Quantitation of the relative PFKFB3 levels after normalization with loading control COX4 (n = 3, ∗∗∗ p < 0.005). C , Western blot showing the relative levels of PNKP and PFKFB3 in the mitochondrial extract of HD patients vs. age-matched control subjects’ frontal cortex. COX4: mitochondrial loading control. In the PFKFB3 immunoblot, upper band indicates a non-specific higher molecular weight cross-reactive band. Lower panel : Quantitation of the relative PFKFB3 levels after normalization with loading control COX4 (n = 3, ∗∗∗ p < 0.005).

Exogenous F2,6BP alleviates pathogenic aggregates in HD cells. A , benzonase-treated mitochondrial extracts from Q-7, mock and F2,6BP-treated (100 μM, 72 h) Q-111 cells were immunoprecipitated (IP’d) with anti-PNKP antibody (PNKP IP); or control IgG and tested for the presence of associated proteins (shown in the right ) using specific Abs (n = 3). B , HTT aggregation levels in Q-7 ( top ), Q-111 ( middle ) and Q-111 cells treated with F2,6BP (100 μM; bottom ) were assessed with ThT dye, which fluoresces green , and nuclear localization was indicated by NucRed dye, providing a cyan signal in the merged images. Imaging was performed on the EVOS M5000 system at 200X magnification. ( Bottom ) Relative quantification of the mean fluorescence intensity (in arbitrary units) (∗ p < 0.05, between Q-7 and Q-111 cells and Q-111 cells + F2,6BP; ns = non-significant, p > 0.05, between Q-7 vs Q-111 (F2,6BP supplemented) cells. C , immunofluorescence micrographs show HTT expression and aggregation in Q-7 ( top ), Q-111 ( middle ) and Q-111 cells treated with F2,6BP ( bottom ). Cells were stained with Anti-HTT antibody MW8, visualized using a mouse secondary antibody conjugated to Alexa Fluor568, resulting in red fluorescence. The nuclei were counter stained with DAPI. Images were captured at 600X magnification using a SoRa super-resolution spinning disk confocal system with motorized FRAP/photobleaching.
