Drug Combo Shuts Down Stem Cells, Tumor Growth in Lung Cancer

JACKSONVILLE, Fla. — Researchers on Mayo Clinic’s Florida campus have shut down one of the most common and lethal forms of lung cancer by combining the rheumatoid arthritis drug auranofin with an experimental targeted agent. The combination therapy worked in a laboratory study to stop lung adenocarcinoma associated with mutation of the KRAS gene. The [...]

Abstract Receptor tyrosine kinases (RTKs) such as the insulin-like growth factor type 1 receptor (IGF-1R) control important biological activities as well as being involved in pathological processes. Due to their supportive nature in many human cancers they have long been considered attractive therapeutic targets. However, lessons learnt from early targeting trials highlight that a simple "active versus inactive" state model with classical kinase-only signaling is overly simplistic and does not describe reality. A vast amount of evidence exists disproving this model and hence provides a rational explanati...

Abstract It takes several months to form the 3-dimensional morphology of the human embryonic brain. Therefore, establishing a long-term culture method for neuronal tissues derived from human induced pluripotent stem (iPS) cells is very important for studying human brain development. However, it is difficult to keep primary neurons alive for more than 3 weeks in culture. Moreover, long-term adherent culture to maintain the morphology of telencephalic neuron aggregates induced from human iPS cells is also difficult. Although collagen gel has been widely used to support long-term culture of cells, it is not clear whe...

Contributors : Feng Zhou ; Shuai Gao ; Dong Han ; Changmeng CaiSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensThe aberrant activation of the ERG oncogenic pathway due to TMPRSS2-ERG gene fusions is the major driver of prostate cancer initiation and progression. We identified the alpha1 and beta1 subunits of soluble guanylyl cyclase (GUCY1A1, GUCY1B1) as major ERG-regulated genes in prostate cancer cells. Soluble guanylyl cyclase (sGC) is the major mediator of nitric oxide signaling in cells that, upon nitric oxide binding, catalyzes the synthesis of cGMP and subsequently activates PK...

Objective: Multi electrodes arrays (MEAs) combined with cardiomyocytes derived from human-induced pluripotent stem cells (hiPSC-CMs) can enable high- or medium-throughput drug screening in safety pharmacology. This technology has recently attracted a lot of attention, in particular from an international initiative named CiPA. But it is currently limited by the difficulty to analyze the measured signals. We propose a strategy to analyze the signals acquired by the MEA and to automatically deduce the channels affected by the drug. Methods: Our method is based on the bidomain equations, a model for the MEA electrodes, and an ...

In this study, a comprehensive dielectric spectroscopy study is conducted for the first time to characterize the ultra-wideband dielectric properties of freshly excised normal and malignant skin tissues obtained from skin cancer patients having undergone Mohs micrographic surgeries at Hackensack University Medical Center. Measurements are conducted using a precision slim-form open-ended coaxial probe in conjunction with a millimeter-wave vector network analyzer over the frequency range of 0.5–50 GHz. A one-pole Cole–Cole model is fitted to the complex permittivity dataset of each sample. Statistically considera...
