Objective: To discuss the effect of Buqing granules-medicated sera on the human lens epithelial cells induced by high glucose. Method: Human lens epithelial (HLE) cell lines were cultured in vitro. HLE cells of blank control group were cultured in the normal nutrient solution for 48 h. In addition to that
model group was also added with 30.0 mmol·L-1 glucose for 48 h. In addition to that
treatment group was also added with different medicated sera and cultured for 48 h. The cell's activity of proliferation was detected by CCK-8 assay. Protein expressions of Pink-1
Parkin
p62 were detected by Western blot. Result: According to CCK-8 assay
model group showed a higher HLE cells proliferation activity than the blank group (P<0.01). Compared with model group
the cell's activity of proliferation of Qiju group and high
middle and low-dose Buqing granules groups were lower (P<0.01). Compared with Qiju group
the cell's activity of proliferation of middle-dose Buqing granules group was obviously decreased (P<0.01). Among different Buqing granules groups
the cell's activity of proliferation of middle-dose Buqing Granules group was significantly decreased (P<0.01). According to immunofluorescence staining
Pink-1
Parkin
p62 proteins were expressed mainly in cell cytoplasm and rarely in nuclei. According to Western blot
compared with blank group
protein expression levels of Pink-1
Parkin of model group were increased (P<0.01)
and p62 expression was decreased (P<0.01). Compared with model group
protein expression levels of Pink-1
Parkin of Qiju group and middle-dose Buqing granules group were increased(P<0.01)
and p62 expression was decreased (P<0.01). Compared with Qiju group
protein expression levels of Pink-1
Parkin of middle-dose Buqing granules group were increased (P<0.01)
and p62 expression was decreased (P<0.01). Conclusion: Buqing granules have a significant effect on protein expressions related to mitochondrial autophagy of HLE cells induced by high glucose. The change in mitochondrial autophagy may be one of the mechanisms of Buqing Granules in alleviating cataract.
