Cumulative life stressors and stress response to threatened preterm labour as birth date predictors.

Arch Gynecol Obstet 2021 Sep 21. Epub 2021 Sep 21.

Neonatal Research Unit, Health Research Institute La Fe, Av Fernando Abril Martorell, 106, 46026, Valencia, Spain.

Purpose: Preterm birth represents one of the main causes of neonatal morbimortality and a risk factor for neurodevelopmental disorders. Appropriate predictive methods for preterm birth outcome, which consequently would facilitate prevention programs, are needed. We aim to predict birth date in women with a threatened preterm labour (TPL) based on stress response to TPL diagnosis, cumulative life stressors, and relevant obstetric variables. Read More

The Immunomodulatory Effect of Triptolide on Mesenchymal Stromal Cells.

Front Immunol 2021 16;12:686356. Epub 2021 Aug 16.

Department of Cell Processing and Transfusion, The Institute of Medical Science, The University of Tokyo, Minato-ku, Japan.

Mesenchymal stromal cells (MSCs) are known to have immunosuppressive ability and have been used in clinical treatment of acute graft--host disease, one of severe complications of the hematopoietic stem cell transplantation. However, MSCs are activated to suppress the immune system only after encountering an inflammatory stimulation. Thus, it will be ideal if MSCs are primed to be activated and ready to suppress the immune reaction before being administered. Read More

Superior anticancer effect of biomimetic paclitaxel and triptolide co-delivery system in gastric cancer.

J Biomed Res 2021 Jul;35(4):327-338

Department of Pharmaceutics, School of Pharmacy, Nanjing Medical University, Nanjing, Jiangsu 211166, China.

As a well-known anticancer drug, paclitaxel (PTX), a first-line chemotherapeutic agent, remains unsatisfactory for gastric cancer therapy. It is reported that triptolide (TPL) could enhance the anti-gastric cancer effect of PTX. Considering the poor solubility of both drugs, we developed a red blood cell membrane-biomimetic nanosystem, an emerging tool in drug delivery, to co-load paclitaxel and triptolide (red blood cell membrane coated PTX and TPL co-loaded poly(lactic--glycolic acid) [PLGA] nanoparticles, RP(P/T)).

TPL Inhibits the Invasion and Migration of Drug-Resistant Ovarian Cancer by Targeting the PI3K/AKT/NF-κB-Signaling Pathway to Inhibit the Polarization of M2 TAMs.

Front Oncol 2021 26;11:704001. Epub 2021 Jul 26.

Department of Obstetrics & Gynecology, The Second Affiliated Hospital of Nanchang University, Nanchang, China.

Chemoresistance is the primary reason for the poor prognosis of patients with ovarian cancer, and the search for a novel drug treatment or adjuvant chemotherapy drug is an urgent need. The tumor microenvironment plays key role in the incidence and development of tumors. As one of the most important components of the tumor microenvironment, M2 tumor-associated macrophages are closely related to tumor migration, invasion, immunosuppressive phenotype and drug resistance.

Triptolide targets super-enhancer networks in pancreatic cancer cells and cancer-associated fibroblasts.

Oncogenesis 2020 Nov 9;9(11):100. Epub 2020 Nov 9.

Molecular Medicine Division, Translational Genomics Research Institute, Phoenix, AZ, USA.

The tumor microenvironment in pancreatic ductal adenocarcinoma (PDAC) is highly heterogeneous, fibrotic, and hypovascular, marked by extensive desmoplasia and maintained by the tumor cells, cancer-associated fibroblasts (CAFs) and other stromal cells. There is an urgent need to identify and develop treatment strategies that not only target the tumor cells but can also modulate the stromal cells. A growing number of studies implicate the role of regulatory DNA elements called super-enhancers (SE) in maintaining cell-type-specific gene expression networks in both normal and cancer cells.
