Treatment Patterns by EGFR Mutation Status in Non-Small Cell Lung Cancer Patients in the USA: A Retrospective Database Analysis.

Targeted therapies, including tyrosine kinase inhibitors (TKIs) that target the sensitizing epidermal growth factor receptor (EGFR) gene are recommended for patients with non-small cell lung cancer (NSCLC). Most patients with NSCLC who test positive for the EGFR mutation and receive TKIs develop resistance to these drugs. Questions remain regarding which treatment sequence is optimal for patients ...

Upregulation of MiR-126 Delays the Senescence of Human Glomerular Mesangial Cells Induced by High Glucose via Telomere-p53-p21-Rb Signaling Pathway.

Diabetic kidney disease (DKD) is a microvascular complication of type 2 diabetes. The study of DKD mechanisms is the most important target for the prevention of DKD. Renal senescence is one of the important pathogeneses for DKD, but the mechanism of renal and cellular senescence is unclear. Decreased expression of circulating miR-126 is associated with the development of DKD and may be a promising...

Donor-derived marrow mesenchymal stromal cell co-transplantation following a haploidentical hematopoietic stem cell transplantation trail to treat severe aplastic anemia in children.

Haploidentical hematopoietic stem cell transplantation (haplo-HSCT) is associated with an increased risk of graft failure and severe graft-versus-host disease (GVHD). Recent studies have shown that mesenchymal stromal cells (MSCs) display potent immunosuppressive effects and can support normal hematopoiesis. In a multi-center trial, we co-transplanted culture-expanded donor-derived bone marrow MSC...

Platelets: the holy grail in cancer blood biomarker research?

We would like to promote the fact that platelets are increasingly emerging as a rich source of potential biomarkers for cancer. Blood platelets contain vast amounts of bioactive proteins, such as growth factors, chemokines, and cytokines. These proteins are either synthesized by the megakaryocytes that produce the platelets or are sequestered by the circulating platelets from the blood, in which c...

Lung cancer with bone metastases in the United States: an analysis from the Surveillance, Epidemiologic, and End Results database.
