Novel therapeutic strategies for autoimmune and inflammatory rheumatic diseases
Drug Discov Today. 2023 May 8:103612. doi: 10.1016/j.drudis.2023.103612. Online ahead of print.ABSTRACTDrugs of unknown mechanisms of action are no longer being developed because we have largely capitalized on our improved understanding of the immunopathogenesis of immune-mediated inflammatory diseases (IMIDs) to develop therapeutic monoclonal antibodies (mAbs) and targeted treatments. These therapies have profoundly revolutionized the care of IMIDs. However, because of the heterogeneity of IMIDs and the redundancy of the targeted molecular pathways, some patients with IMIDs might not respond to a specific targeted drug or...

Biomimetic cell membrane-coated nanocarriers for targeted siRNA delivery in cancer therapy
Drug Discov Today. 2023 Feb 2:103514. doi: 10.1016/j.drudis.2023.103514. Online ahead of print.ABSTRACTSmall interfering RNA (siRNA) therapeutics for cancer are a focus of increasing research interest. However, the major obstacle to their clinical application is the targeted delivery of siRNA to cancer cells at desirable levels. Cell membrane-coated nanocarriers have the advantage of combining the properties of both cell membranes and nanoparticles (NPs). In this review, we highlight the most common RNAi therapeutics and the extracellular and intracellular barriers to siRNA delivery. Moreover, we discuss clinical applicati...

MiR-133a-3p/Sirt1 epigenetic programming mediates hypercholesterolemia susceptibility in female offspring induced by prenatal dexamethasone exposure
In conclusion, PDE can cause persistent enhancement of hepatic cholesterol synthesis function before and after birth through GR/miR-133a-3p/Sirt1 pathway, eventually leading to increased hypercholesterolemia susceptibility in female offspring rats.PMID:36326533 | DOI:10.1016/j.bcp.2022.115306

SOX2 function in cancers: Association with growth, invasion, stemness and therapy response
Biomed Pharmacother. 2022 Oct 19;156:113860. doi: 10.1016/j.biopha.2022.113860. Online ahead of print.ABSTRACTCancer is a leading cause of death worldwide and around 10 million deaths in 2020 were related to cancer. There are a number of therapeutic modalities for cancer such as chemotherapy, radiotherapy and surgery. However, tumor cells have capacity of developing resistance to chemotherapy and radiotherapy. Genetic mutations participate in development and progression of cancer. The current review focuses on the role of SOX2 transcription factor in cancer. SOX2 has capacity of increasing growth and metastasis of cancer c...

Positive programming of the GC-IGF1 axis mediates adult osteoporosis susceptibility in male offspring rats induced by prenatal dexamethasone exposure
In conclusion, PDE-induced intrauterine hypoglucocorticoid exposure could positively program IGF1 expression in bone tissue through the GRα/miR-130a-5p/HDAC4 pathways, thus mediating osteogenic dysdifferentiation and adult osteoporosis susceptibility in male offspring rats.PMID:36174767 | DOI:10.1016/j.bcp.2022.115264

Sulforaphane regulates the proliferation of leukemia stem-like cells via Sonic Hedgehog signaling pathway
This study explored the effects and related molecular mechanisms of SFN on the proliferation of leukemia stem-like cells in acute myeloid leukemia cells. We found that SFN inhibited the proliferation of leukemia stem-like cells in vitro and in vivo. Meanwhile, we observed that SFN could regulate the stem characteristic of leukemia cells. After SFN treatment, the expression of the key players in the Sonic Hedgehog (Shh) signaling pathway was significantly decreased at the transcriptional and protein levels. To further determine the contribution of the Shh signaling molecular mechanism to SFN-mediated self-renewal capability...

Targeting CDK7 reverses tamoxifen resistance through regulating stemness in ER+ breast cancer
CONCLUSION: Our data indicate, for the first time, that CDK7-targeted therapy in ER+ breast cancer ameliorates tamoxifen resistance, at least in part, by inhibiting cancer stemness. Thus, targeting CDK7 might represent a potential approach for relieving tamoxifen resistance in ER+ breast cancer.PMID:35000145 | DOI:10.1007/s43440-021-00346-9
