RESUMEN

Objective:To study the efficacy and mechanism of Shugan Jianpi Jiedu prescription (SJJ) in the treatment of triple-negative breast cancer through <italic>in vitro</italic> cell experiments. Method:The following groups were set up in this study: a normal serum group,a pirarubicin group,and low-,medium-, and high-dose SJJ-medicated serum groups. Twenty SD rats were randomly divided into four groups and administered with SJJ solution (16.8,8.2,4.05 g·kg<sup>-1</sup>) and normal saline (equal volume) according to the body surface area to prepare serum. MDA-MB-231 cells were treated separately. The proliferation, migration and invasion of MDA-MB-231 cells were detected by the cell counting kit-8(CCK-8),wound healing assay and transwell cell invasion assay. The phosphoinositide 3-kinase (PI3K),protein kinase B (Akt), and mechanistic target of rapamycin (mTOR) protein expression levels in MDA-MB-231 cells were tested by the Western blot. Result:The cell proliferation in the three different doses of medicated serum groups and the pirarubicin positive control group was significantly inhibited as compared with that in the normal serum group(<italic>P</italic><0.01),and there was no statistical difference for this between the medium/high dose medicated serum group and the pirarubicin positive control group.The wound healing in the SJJ-medicated serum groups and the pirarubicin group was slowed down as compared with that in the normal serum group (<italic>P</italic><0.01),and the effect in the SJJ-medicated serum groups was weaker than that in the pirarubicin group (<italic>P</italic><0.05,<italic>P</italic><0.01). The number of cells invading the lower transwell chamber was decreased as compared with that in the normal serum group (<italic>P</italic><0.01),and there was no statistical difference between the medium-/high-dose SJJ-medicated serum groups and the pirarubicin group. Western blot results showed that 48 h after treatment,the PI3K,Akt, and mTOR expression levels in the cells of SJJ-medicated serum groups and the pirarubicin group were lower than those of the normal serum group(<italic>P</italic><0.01). Conclusion:The SJJ-medicated serum could inhibit the proliferation, migration and invasion of MDA-MB-231 cells presumedly by down-regulating the protein expression levels in the PI3K/Akt/mTOR signaling pathway.

RESUMEN

Objective:To explore the effects and mechanism of zedoary turmeric oil and its active components on the vascular endothelial growth factor A (VEGFA), signal transducer and activator of transcription 3 (STAT3), and mechanistic target of rapamycin (mTOR) in the ovarian cancer (OC). Method:Network pharmacology technology was employed to analyze the mechanism of Curcumae Rhizoma on OC. Bioinformatics was used to analyze the expression of VEGFA, STAT3, and mTOR in OC and the effect on the prognosis of OC to explore the feasibility of zedoary turmeric oil in regulating VEGFA, STAT3, and mTOR in OC.The xenograft tumor model of nude mice was established, and the effects of zedoary turmeric oil and its active components on VEGFA, STAT3, and mTOR in OC were observed by hematoxylin-eosin (HE) staining, real-time fluorescence-based quantitative polymerase chain reaction (Real-time PCR), Western blot, and immunohistochemistry (IHC). Result:Bioinformatics analysis and literature research showed that VEGFA, STAT3, and mTOR played a special regulatory role in the occurrence and development of OC, and were potential key targets for the proliferation of OC. Network pharmacology analysis revealed that Curcumae Rhizoma could regulate multiple disease targets of OC, and mediate VEGFA, STAT3, and mTOR in OC through these multiple targets. As demonstrated by HE staining, the tumor cells in the model group were densely arranged, with no erosion on the edge and no vesicles inside. Compared with the model group, the cell density in other treatment groups was reduced, and strip-shaped erosion on the edge and small empty vesicles were observed in the tumor tissue, especially in the zedoary turmeric oil group. According to the results of Real-time PCR and IHC, zedoary turmeric oil and its active components could inhibit the mRNA and protein expression of VEGFA, STAT3, and mTOR in the OC tissue (<italic>P</italic><0.05). Conclusion:Zedoary turmeric oil and its active components could reduce the expression of VEGFA, STAT3, and mTOR in tumor tissue of nude mice, and inhibited the proliferation of OC through VEGFA, STAT3, and mTOR.

RESUMEN

Objective: To investigate the protective effect of extracts from Ginseng Radix et Rhizoma, Notoginseng Radix et Rhizoma and Chuanxiong Rhizoma on vascular senescence induced by high glucose in mice from adenosine 5'-monophosphate (AMP)-activated protein kinase/mechanistic target of rapamycin (AMPK/mTOR) pathway. Method: A total of 130 male C57BL/6 mice were randomly divided into control group and high glucose group. The high glucose group was intraperitoneally injected with streptozocin(STZ) and fed with a high-fat diet continuously for seven months. Mice were divided into 4 groups:model group, low-dose extracts from Ginseng Radix et Rhizoma, Notoginseng Radix et Rhizoma and Chuanxiong Rhizoma(0.819 g·kg-1) group, high-dose extracts from Ginseng Radix et Rhizoma, Notoginseng Radix et Rhizoma and Chuanxiong Rhizoma group (1.638 g·kg-1) and metformin group (150 mg·kg-1), and intragastrically administered once a day for nine weeks. The changes in body weight and blood glucose were measured. At the end of the administration, htoxylin eosin(HE) was performed for the detection of aortic morphology, and the expressions of cyclin-dependent kinase inhibitor 2A (p16), cyclin-dependent kinase inhibitor 1A (p21), AMPK, p-AMPK, mTOR, p-mTOR, liver kinase B1 (LKB1), p-LKB1, Ribosomal protein s6 kinase (p70s6k) and p-p70s6k proteins in mouse aorta were detected by Western blot. Result: Compared with blank group, mice in model group had lower body weight and higher blood glucose (PPPPPPPPPPPConclusion: High glucose can induce vascular senescence, and extracts from Ginseng Radix et Rhizoma, Notoginseng Radix et Rhizoma and Chuanxiong Rhizoma can improve vascular aging induced by high glucose through AMPK/mTOR pathway.
