Abstract

Multidrug resistance in malignant tumours hinders the treatment of tumours. Studies showed that astragalus polysaccharides (APS), one major active ingredient of astragalus, enhanced the sensitivity of non-small cell lung cancer and liver cancer cells to chemotherapeutic drug. However, the effect of APS on ovarian cancer is still unclear. In this study, we will examine the sensitizing effect of APS on SKOV3 cells to cisplatin and explore the possible mechanism. MTT assay was employed to examine the viability of SKOV3 after treatment with APS and cisplatin. The cell apoptosis rate was determined by flow cytometry. The expression of Bax, Bcl-2, Caspase-3, and c-Jun N-terminal kinases 1/2 (JNK1/2) was measured using Western blotting and RT-PCR. APS synergistically promoted the inhibitory effect of cisplatin on SKOV3 cell viability. Flow cytometry showed that APS promoted cisplatin-induced apoptosis of SKOV3 cell lines. Further studies showed that APS down-regulated the expression of Bcl2, increased the expression of Bax and caspase 3 and activated JNK1/2 signalling pathway. The JNK inhibitors significantly rescued the proliferation inhibition induced by the drugs. Astragalus polysaccharides increased the sensitivity of SKOV3 cells ...Continue Reading

CREs: Gene & Cell Therapy

Gene and cell therapy advances have shown promising outcomes for several diseases. The role of cis-regulatory elements (CREs) is crucial in the design of gene therapy vectors. Here is the latest research on CREs in gene and cell therapy.

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Autoimmune Polyendocrine Syndromes

This feed focuses on a rare genetic condition called Autoimmune Polyendocrine Syndromes, which are characterized by autoantibodies against multiple endocrine organs. This can lead to Type I Diabetes.

Autoimmune Polyendocrinopathies

Autoimmune polyendocrinopathies, also called polyglandular autoimmune syndromes (PGASs), or polyendocrine autoimmune syndromes(PASs), are a heterogeneous group of rare diseases characterized by autoimmune activity against more than one endocrine organ, although non-endocrine organs can be affected. Discover the latest research on autoimmune polyendocrinopathies here.

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.
