Abstract
Breast cancer (BC) is the most common tumor in women, and its incidence is increasing, ranking first among female malignant tumors. It is urgently needed to find new and reliable biomarkers of BC and to understand the cellular changes that cause metastasis. Stomatin-like protein-2 (SLP-2) is a member of the stomatin protein superfamily. Studies have shown that SLP-2 was highly expressed in some tumors and played an important role in tumor genesis and development. SLP-2 regulated the extracellular signal-regulated kinase (ERK) pathway, and activation of ERK phosphorylated FOXO3a, which was involved in BC progression. However, its possible role in the progression of BC remains unclear. In this study, we found the high expression of SLP-2 in BC tissues and cells. SLP-2 promoted the viability of BC cells. In addition, we found that SLP-2 stimulated the motility of BC cells in vitro. Mechanically, our results revealed that SLP-2 could mediate FOXO3a expression and ERK signaling pathway, thereby contributing to the viability and motility of BC cells. Therefore, SLP-2 has the potential to serve as a promising target for BC treatment.

Cell Death Discov 2023; 9:63. [PMID: 36788223 PMCID: PMC9929064 DOI: 10.1038/s41420-023-01350-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Revised: 01/27/2023] [Accepted: 01/30/2023] [Indexed: 02/16/2023] Open
Abstract
Myocardial fibrosis, oxidative stress, and autophagy both play key roles in the progression of adverse cardiac remodeling. Stomatin-like protein 2 (SLP-2) is closely related to mitochondrial function, but little is known about its role and mechanism in cardiac remodeling. We developed doxorubicin (Dox), angiotensin (Ang) II, and myocardial ischemia-reperfusion (I/R) injury induced cardiac remodeling model and Dox treated H9C2 cell injury model using SLP-2 knockout (SLP-2-/-) mice and H9C2 cells with low SLP-2 expression. We first examined cardiac functional and structural changes as well as levels of oxidative stress, apoptosis and autophagy. We found that SLP-2 deficiency leads to decreased cardiac function and promotes myocardial fibrosis. After Dox and Ang II treatment, SLP-2 deficiency further aggravated myocardial fibrosis, increased myocardial oxidative stress and apoptosis, and activated autophagy by inhibiting PI3K-Akt-mTOR signaling pathway, ultimately exacerbating adverse cardiac remodeling. Similarly, SLP-2 deficiency further exacerbates adverse cardiac remodeling after myocardial I/R injury. Moreover, we extracted cardiomyocyte mitochondria for proteomic analysis, suggesting that SLP-2 deficiency may be involved in myocardial I/R injury induced adverse cardiac remodeling by influencing ubiquitination of intramitochondrial proteins. In addition, the oxidative stress, apoptosis and autophagy levels of H9C2 cells with low SLP-2 expression were further enhanced, and the PI3K-Akt-mTOR signaling pathway was further inhibited under Dox stimulation. Our results suggest that SLP-2 deficiency promotes myocardial fibrosis, disrupts normal mitochondrial function, overactivates autophagy via PI3K-Akt-mTOR signaling pathway, affects the level of ubiquitination, leads to irreversible myocardial damage, and ultimately exacerbates adverse cardiac remodeling.

SLP-2 regulates the generation of reactive oxygen species and the ERK pathway to promote papillary thyroid carcinoma motility and angiogenesis. Tissue Cell 2023; 80:101997. [PMID: 36527788 DOI: 10.1016/j.tice.2022.101997] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Revised: 12/05/2022] [Accepted: 12/05/2022] [Indexed: 12/12/2022]
Abstract
Although papillary thyroid cancer (PTC) has a generally decent prognosis, approximately 10% of patients experience recurrence, which is frequently associated with distant metastasis. Stomatin-like protein 2 (SLP-2), a protein located in the mitochondrial intermembrane space, is thought to be a possible cancer promoter. This study aimed to discover the involvement of SLP-2 in PTC motility and angiogenesis, and to initially explore its mechanism. According to the CCLE database, SLP-2 was universally increased in various cancers. Then SLP-2 expression in PTC cell lines was evaluated. Thereafter the influences of SLP-2 knockdown on cell migration, invasion, epithelial-mesenchymal transition (EMT), and angiogenesis were assessed, respectively. The mediated roles of reactive oxygen species (ROS) and MAPKs in the SLP-2 regulation were likewise determined. SLP-2 was discovered to be upregulated in PTC cells, and its knockdown could suppress cell migration, invasion, EMT, and angiogenesis. Declined SLP-2 expression also facilitated ROS generation and inhibited phosphorylation of MAPKs. Moreover, ERK agonist and ROS scavenger treatment partially reversed the impacts of SLP-2 knockdown on cells, indicating SLP-2 regulated generation of ROS and ERK pathway to promote PTC motility and angiogenesis. Generally, SLP-2 appears to be one of the major genes in the pathogenesis of PTC. Silencing its expression may have an impact on the onset and evolution of PTC. The fact that SLP-2 has a considerable influence on ROS levels implies that PTC can be treated by boosting ROS levels.

Annexin A2 Improves the Osteogenic Differentiation of Mesenchymal Stem Cells Exposed to High-Glucose Conditions through Lessening the Senescence. Int J Mol Sci 2022; 23:ijms232012521.

Abstract
Osteoporosis is frequently found in chronic diabetic patients, and it results in an increased risk of bone fractures occurring. The underlying mechanism of osteoporosis in diabetic patients is still largely unknown. Annexin A2 (ANXA2), a family of calcium-binding proteins, has been reported to be involved in many biological process including bone remodeling. This study aimed to investigate the role of ANXA2 in mesenchymal stem cells (MSCs) during in vitro osteoinduction under high-glucose concentrations. Osteogenic gene expression, calcium deposition, and cellular senescence were determined. The high-glucose conditions reduced the osteogenic differentiation potential of the MSCs along with the lower expression of ANXA2. Moreover, the high-glucose conditions increased the cellular senescence of the MSCs as determined by senescence-associated β-galactosidase staining and the expression of p16, p21, and p53 genes. The addition of recombinant ANXA2 could recover the glucose-induced deterioration of the osteogenic differentiation of the MSCs and ameliorate the glucose-induced cellular senescence of the MSCs. A Western blot analysis revealed an increase in p53 and phosphorylated p53 (Ser 15), which was decreased by recombinant ANXA2 in MSC osteoblastic differentiation under high-glucose conditions. Our study suggested that the alteration of ANXA2 in high-glucose conditions may be one of the plausible factors in the deterioration of bones in diabetic patients by triggering cellular senescence.
