lncRNA SNHG11 Facilitates Prostate Cancer Progression through the Upregulation of IGF-1R Expression and by Sponging miR-184

Researchers investigated the functional role and molecular mechanisms of SNHG11 in prostate cancer (PCa) progression. It was revealed that the SNHG11 expression levels were significantly upregulated in PCa tissues, in comparison with those in adjacent normal tissues.

Androgen Receptor Antagonists Produced by Streptomyces Overcome Resistance to Enzalutamide

From the natural product screening, the novel compound arabilin was isolated from Streptomyces sp. MK756-CF1. Unlike STK765173, arabilin could overcome resistance to enzalutamide.

Mkx Mediates Tenogenic Differentiation but Incompletely Inhibits the Proliferation of Hypoxic MSCs

qRT-PCR, western blot, and immunofluorescence staining were performed to evaluate the expression of Mkx and other tendon-associated markers in adipose-derived MSCs and bone marrow-derived MSCs under hypoxia condition.

Donor-Derived CD7 Chimeric Antigen Receptor T Cells for T-Cell Acute Lymphoblastic Leukemia: First-in-Human, Phase I Trial

In this single-center, Phase I trial, we administered anti-CD7 chimeric antigen receptor (CAR) T cells, manufactured from either previous stem-cell transplantation donors or new donors, to patients with relapsed or refractory T-cell acute lymphoblastic leukemia, in single infusions at doses of 5 × 105 or 1 × 106 cells per kilogram of body weight.

Hijacking TYRO3 from Tumor Cells via Trogocytosis Enhances NK-Cell Effector Functions and Proliferation

Investigators found that although NK cells did not express endogenous TYRO3 on the cell surface, activated NK cells rapidly acquired TYRO3 from tumor cells via trogocytosis in vitro and in vivo.

MASTL Regulates EGFR Signaling to Impact Pancreatic Cancer Progression

Based on a comprehensive investigation involving pancreatic cancer (PC) patient samples, murine models of PC progression, and loss and gain of function studies, researchers reported a previously undescribed critical role of microtubule-associated serine/threonine-protein kinase-like (MASTL) in promoting cancer malignancy and therapy resistance.

Stress-Primed Secretory Autophagy Promotes Extracellular BDNF Maturation by Enhancing MMP9 Secretion

Brain-derived neurotrophic factor (BDNF) is essential for adult synaptic plasticity and its pathway is associated with major depression and posttraumatic stress disorder. Researchers found that stress-enhanced matrix metalloproteinase 9 (MMP9) secretion increased the cleavage of proBDNF to its mature form mBDNF.

Autoantibodies against NMDA Receptor 1 Modify Rather Than Cause Encephalitis

Investigators tested whether following immunization with a “cocktail” of 4 NMDAR1 peptides, induction of a spatially and temporally defined sterile encephalitis by diphtheria toxin-mediated ablation of pyramidal neurons would modify/aggravate the ensuing phenotype.
