New Insights into Hyperthermia Cancer Therapy

In a paper published in the Journal of Physics D: Applied Physics, a team of investigators led by Kevin O’Grady from the University of York have shown that the amount of heat generated by magnetic nanoparticles can be understood when both the physical and hydrodynamic size distributions for the samples are known to high accuracy.

GorgoulisAbstractCellular senescence is a stress response mechanism ensuring homeostasis. Its temporal activation during embryonic development or normal adult life is linked with beneficial properties. In contrast, persistent (chronic) senescence seems to exert detrimental effects fostering aging and age-rel...

In this study, we found that CD169+ macrophages depletion inhibited the growth of established Lewis lung carcinoma tumors in mice. Benefits must be weighed against potential adverse effects in cancer therapy. Here, we investigated the adverse effects of CD169+ macrophages depletion on bone and bone marrow in mice bearing Lewis lung carcinoma tumors. Our studies showed that depletion of CD169+ macrophages in LLC tumor-bearing mice disrupted bone homeostasis, including bone weight loss and bone mineral density decrease. Further studies revealed that bone marrow erythropoiesis was severely impaired after depletion of CD169+ m...

Calpain 2 knockdown promotes cell apoptosis and restores gefitinib sensitivity through epidermal growth factor receptor/protein kinase B/survivin signaling. Oncol Rep. 2018 Aug 02;: Authors: Zhang G, Fang T, Chang M, Li J, Hong Q, Bai C, Zhou J Abstract Gefitinib, an epidermal growth factor receptor (EGFR)‑specific drug, is effective for ~1 year, after which resistance is inevitable. Calpain 2 (CAPN2) is known to serve a role in the drug response and resistance in certain cancer therapies. However, the full function of CAPN2, particularly in non‑small cell lung cancer, has not yet be...

AbstractLiposomal therapies opened the chapter of nanomedicine, in 1995, with the approval of liposomal doxorubicin (Doxil®) for the treatment of numerous types of cancer. For the first time, liposomes permitted the employment of potent chemotherapeutic agents with improved pharmacokinetic and pharmacodynamic profiles, with less undesired side effects. Liposomal therapies allow the drug encapsulation and more selective delivery in the tumor bed, particularly due to the enhanced permeation and retention effect. These unique characteristics explain why liposomal therapies are being increasingly considered as alternatives...

This article provides an overview of AZD1775, based on English peer-reviewed articles on MEDLINE. The authors highlight the data from the published preclinical and clinical studies. Expert opinion: A majority of the current clinical trials focus on AZD1775 combined with chemotherapy or radiation. Treatment with AZD1775 was tolerated and antitumor activity has been observed, especially in patients with advanced malignancies harboring G1 checkpoint aberrations and/or DNA damage repair defects. Thus, identification of the molecular subtypes that benefit most from the treatment with AZD1775 alone or in combination may provide ...

Abstract Aneuploidy is a hallmark of cancer. Defects in chromosome segregation result in aneuploidy. Multiple pathways are engaged in this process, including errors in kinetochore-microtubule attachments, supernumerary centrosomes, spindle assembly checkpoint (SAC) defects, and chromosome cohesion defects. Although aneuploidy provides an adaptation and proliferative advantage in affected cells, excessive aneuploidy beyond a critical level can be lethal to cancer cells. Given this, enhanced chromosome missegregation is hypothesized to limit survival of aneuploid cancer cells, especially when compared to diploid cel...

This study aimed to investigate the effect of Ru (Rut) on angiogenesis, and the underlying regulation mechanism of signal transduction. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay, adhesion inhibition experiment, migration inhibition experiment, and chick embryo chorioallantoic membrane (CAM) assays were performed on models of angiogenesis. The potential targets of rutaecarpine (Ru) were reverse screened with Discovery Studio 2017. The interaction between the compound and target were detected by surface plasmon resonance (SPR), enzyme-activity experiment, and Western blot assay. The obtaine...
