Abstract

Human epidermal growth factor receptor 2 (HER-2) is used as a marker for the diagnosis and prognosis of breast cancer. However, the molecular mechanisms involving HER2 in breast cancer require further study. Herein, we used the bioinformatics approaches to identify important pathways and hub genes in breast cancer affected by HER-2. The results showed that HER-2 is highly expressed in ovarian cancer and is closely related to the overall survival and progression-free survival of breast cancer. A total of 3014 downregulated genes and 4121 upregulated genes were identified under Gene Expression Omnibus (GEO) database with the GEO2R tool. Among them, the top 10 hub genes including CCNB1, KIF11, BUB1B, TOP2A, ASPM, MAD2L1, BUB1, RRM2, EGFR, and FN1 demonstrated by connectivity degree in the protein-protein interaction (PPI) network were screened out. In Kaplan–Meier plotter survival analysis, the overexpression of CCNB1, EGFR, MAD2L1, ASPM, and RRM2 were shown to be associated with an unfavourable prognosis in HER-2 positive breast cancer patients. In conclusion, we have identified important signalling pathways involving HER-2 that affect breast cancer. These findings could provide new insights outlining mechanisms involving HER-2 gene expression in breast cancer and provides a rationale for the novel treatment of breast cancer.

Abstract

High exposure to ultraviolet light and chemicals causes cell senescence due to the overproduction of reactive oxygen species (ROS). Cell senescence is known as one of the causes of degenerative diseases. Reducing ROS levels using antioxidant compounds can overcome cell senescence. This study aimed to evaluate the potential of Moringa leaf extract (EDK) as an anti-aging agent and predict the molecular mechanisms underlying its activity. EDK active compounds were identified through qualitative phytochemical screening, a cytotoxic assay was evaluate using MTT assay, ROS level calculate under DCFDA flow cytometry assay, and cell senescence analyze using SA-β-galactosidase assay. The molecular mechanism that plays an important role in senescence was analyzed through bioinformatics studies and molecular docking in silico to investigate the interaction strength of the active compound EDK with the target protein. The results showed that the EDK ethanol extract contained flavonoid, phenolic, alkaloid, saponin, and steroid compounds. This extract did not give any cytotoxic effect on NIH3T3 cells, as evidenced by the IC50 value of 420μg/mL. EDK concentrations of ¼IC50 (105μg/mL) and ½IC50 (210μg/mL) significantly reduced ROS level in dose-dependent manner in the NIH3T3 cell population with high oxidative stress induced by Doxorubicin 10nM (Dox). The percentage of senescence cells also decreased due to EDK 210μg/mL administration up to 47.60% compared to the positive aging control Dox 10nM (78.90%). Bioinformatics studies found that p21 and TP53 proteins were most directly affected by EDK active compounds in the senescence pathway. The quercetin compound in EDK has the most robust interaction strength against p21 and TP53 proteins compared to ligands. In conclusion, it can be concluded that the active compound EDK can suppress intracellular ROS levels and compete with p21 and TP53 proteins in preventing cell senescence.

Abstract

Type 1 diabetes mellitus (T1DM) is an autoimmune disease characterised by the cessation of insulin production due to pancreatic β-cell damage resulting in an increase in blood glucose. This study aims to analyse the effect of hypoxic secretome MSCs on the angiogenesis process through the observation of VEGF levels in T1DM rats model. The twenty animal model were randomly assigned to four groups: control T1DM, T1DM with HS-MSCs 0.5 mL intraperitoneal treatment (T1), and TIDM with hypoxic secretom mesenchymal stem cells (HS-MSCs) 1 mL intraperitoneal treatment (T2). The T1DM rats model was induced by a single intraperitoneal (IP) injection of freshly prepared streptozotocin (STZ) at a dose of 65 mg/kg of body weight. The VEGF levels was analyses under ELISA assay. The results showed that VEGF levels of T1 (68.86±4.78) and T2 (53.83±10.86) groups were significantly upregulated in treatment of HS-MSCs. Taken together, HS-MSCs potentially reduce glucose levels on T1DM through VEGF up-regulation.

Abstract

This study aimed to determine the effect of administration of Clitorea ternatea flower extract (C. ternatea) in a gel on the expression of MMP-3 and α-SMA in the skin of rat models induced by UVB light exposure. This research design is experimental research with a post-test control group design. This study was divided into four treatment groups: a healthy group, a UVB-negative control, a 5% C. ternatea gel treatment group (T1), and a 10% C. ternatea gel treatment group (T2). Negative control, T1, and T2 control groups were given UVB treatment with 302 nm energy of 160 mJ/cm2 for 5 days. In the treatment groups T1 and T2 were given the gel of C. ternatea from the 6th day until the 14th day. On day 15, all treatment groups were terminated, and the expression of MMP-3 and α-SMA genes was analyzed using qRT-PCR. In the 10% C. ternatea gel treatment group, there was a decrease in MMP-3 gene expression (0.73±0.26) and an increase in α-SMA gene expression (16.4±8.3) compared to the UVB control group which had gene expression. MMP-3 (3.24+1.05) and α-SMA gene expression (0.1±0.0). The administration of C. ternatea gel resulted in a reduction in the expression of the MMP-3 gene and an increase in the expression of the α-SMA gene. Overall, C. ternatea has the potential to prevent UVB-induced hyperpigmentation.

Abstract

Background: UVB irradiation can induce the formation of Reactive Oxygen Species (ROS), which causes the activation of melanin synthesis through the activation of tyrosinase and tyrosinase-related protein-1 (TRP1). Secondary metabolites in stink bean peel extract inhibit ROS production due to exposure to UVB rays. This study aims to determine the effect of administering stink bean peel extract gel on the expression of the tyrosinase and TRp1 genes in mouse skin tissue exposed to UVB. Method: The research design was a posttest-only control group with a completely randomized design method. The samples studied were 24 mice exposed to UVB light with a wavelength of 302 nm and an energy of 390mJ/cm2/day 3 times a week for 2 weeks. This research was carried out in four groups: the healthy group, the negative control group, treatment 1 (T1) with 10% stink bean peel extract gel, and treatment 2 (T2) with 20% stink bean peel extract gel. Tyrosinase and TRP1 gene expression were analyzed using qRT-PCR. Results: qRT-PCR analysis showed that there was a significant decrease in tyrosinase and TRP1 gene expression between groups T1 (tyrosinase 3,19±2,12 and TRP1 4,96±3,42) and T2 (tyrosinase 0,65±0,44 and TRP1 2,22±1,18) compared to negative control (tyrosinase 17,92±3,77 and TRP1 35,91±4,52). Conclusion: The administration of stink bean peel extract gel has shown promising results in reducing the expression of tyrosinase and TRP1 genes in hyperpigmentation mice exposed to UVB light. This suggests that stink bean peel extract could be a safe and effective therapeutic approach for preventing UVB-induced hyperpigmentation.
