Cell injury associated with reactive oxygen species (ROS) has been reported in various muscular disorders. We found that a Cichorium intybus (Cii) extract reduced H(2)O(2)-induced viability loss in C2C12 myoblasts, inhibited oxidative stress-induced apoptosis and increased intracellular heat shock protein 70 (Hsp 70) expression. Cii also inhibited the level of intracellular ceramide. These results indicate that Cii may prevent skeletal muscle atrophy by inducing the expression of Hsp 70 and inhibiting the level of ceramide.

Objectives: The osteogenic potential of periodontal ligament stem cells (PDLSCs) is crucial for periodontal tissue regeneration. Prolonged and excessive oxidative stress (OS) impairs the osteogenic function of PDLSCs. Recently, Semaphorin 3A (Sema3A) has been reported to have multiple roles in bone protection.

The objective of this study is to explore how adipose-derived stem cells (ASCs) regulate mitochondrial structure and function and the impact of this regulation on slowing cellular senescence. HFF-1 cells were induced by HO to establish a cellular senescence model, and ASCs or Mdivi-1 (mitochondrial fission inhibitor) was added. MTT examined the cell proliferation; flow cytometry detected mitochondrial membrane potential as well as apoptosis and cell cycle; kit measured ATP production; ELISA analyzed the levels of interleukin-6 (IL-6), interleukin 1 beta (IL-1β), tumor necrosis factor alpha-like (TNF-α), glutathione (GSH), malondialdehyde (MDA), and superoxide dismutase (SOD); Western blotting and qRT-PCR detected the expression of protein and mRNA levels; and β-galactosidase staining observed the degree of cellular senescence.

Age-related cataracts (ARCs) are associated with increased oxidative stress and cellular senescence. Our objective is to investigate the function of Sirtuin 1 (SIRT1) within ARCs. In ARCs tissues and HO-treated lens epithelial cells (LECs), the expression levels of SIRT1 were examined.

Abnormality of granulosa cells (GCs) is the critical cause of follicular atresia in premature ovarian failure (POF). RIPK3 is highly expressed in GCs derived from atretic follicles. We focus on uncovering how RIPK3 contributes to ovarian GC senescence.

To investigate the effects of long non-coding RNA KLHL7-AS1 (LncRNA KLHL7-AS1) on the proliferation and apoptosis of nucleus pulposus cells under oxidative stress and its mechanisms. Human nucleus pulposus cells (HUM-iCell-s012) were divided into 4 groups, and unoxidized nucleus pulposus cells were transfected with an empty pcDNA vector (pcDNA-control) to serve as the blank control group. Based on previous studies on oxidative stress-induced nucleus pulposus cell senescence and preliminary experiments, oxidative stress was induced by treating nucleus pulposus cells with 400 μmol/L HO.
