Mesothelioma Clinical Trials Involve Gene Therapy

Treatment options for malignant mesothelioma may soon include customized gene therapy, according to thoracic surgeon and scientist Dr. Prasad Adusumilli at Memorial Sloan Kettering Cancer Center in New York. Gene therapy involves a laboratory reprogramming of a patient’s own T cells, which are a type of white blood cell, to recognize and destroy the cancer. The U.S. Food and Drug Administration (FDA) recently approved the first gene therapy specifically for pediatric leukemia, signaling the start of a new approach to cancer treatment in this country. The newly approved treatment is also known as chimeric antigen receptor (CAR) T cell therapy, which includes removing T cells from a patient, arming them with a protein linked to a particular cancer and then returning those cells to the patient. CAR T cell therapy already has shown considerable promise with blood cancers such as leukemia, which prompted the FDA’s groundbreaking approval. But its effectiveness with solid tumors, such as mesothelioma, has been limited until recently. Memorial Sloan Kettering Leading the Way Memorial Sloan Kettering has been a worldwide leader in developing CAR T cell therapy for cancer, making it safer and more effective. Adusumilli, who specializes in thoracic cancers, is the chief investigator of a promising clinical trial involving T cells genetically engineered to target mesothelin, a protein found in almost 90 percent of pleural mesothelioma tumors. Early trial results are encourag...

In this study, we compared the long-term side effects of proton radiation to equivalent doses of X-rays in the initiation and progression of premalignant lesions in a lung cancer susceptible mouse model (K-rasLA1). We show proton irradiation causes more complex DNA damage that is not completely repaired resulting in increased oxidative stress in the lungs both acutely and persistently. We further observed K-rasLA1 mice irradiated with protons had an increased number and size of initiated and premalignant lesions and adenomas that were often infiltrated with inflammatory cells. Proton irradiated mice had a lower median surv...

In this study, we have shown that NOL8, a binding protein of beta-catenin, enhanced the interaction between beta-catenin and TCF4, and activated beta-catenin/TCF signaling. NOL8 is up-regulated in the prostate cancer, and promoted the growth, migration and colony formation of cancer cells. Knocking down the expression of NOL8 inhibited the growth, migration and colony formation of prostate cancer cells. The molecular mechanism study demonstrated that NOL8 promoted the migration and colony formation of cancer cells by activating beta-catenin/TCF signaling. Taken together, this study demonstrated the oncogenic roles of NOL8 ...

Jang, Dae Won Park, Eun Hwa Shon, Sung Ryul Lee, Se Chan KangAbstractVascular inflammation has been suggested to play a key role in the initiation and progression of atherosclerosis. Hyperoside (HPS) is a plant-derived quercetin 3-d-galactoside reported to have anti-inflammatory, anti-oxidant, anti-cancer, anti-hyperglycemic, anti-coagulant, and cardioprotective activities. However, the effects of HPS on vascular inflammation have not been studied. Therefore, in this study, we investigated the suppressive effect of HP...

To achieve these goals, developing drug delivery systems is the key step. The common materials used for drug delivery like liposomes, micelles, dendrimers cannot control the delivery and releasing by spatial and temporal. In this paper, we design a photoresponsive drug delivery system to reduce the side effects of traditional chemotherapy on normal cells and improve...

Authors: Zhang S, Cai J, Xie W, Luo H, Yang F Abstract MicroRNA (miR)-202 has been reported to be involved in the regulation of human cancer progression including bladder cancer, non-small cell lung cancer, pancreatic cancer and esophageal squamous cell carcinoma. However, the function of miR-202 in prostate cancer remains largely unknown. The present study demonstrated that miR-202 was downregulated in human prostate cancer tissues and cell lines. And overexpression of miR-202 significantly inhibited the proliferation, migration and invasion of prostate cancer cells, but induced cell apoptosis. Moreover, miR-202 s...

Authors: Sai Y, Zhang X, Feng M, Tang J, Liao H, Tan L Abstract The aim of the present retrospective study was to investigate the diagnosis, treatment and prognosis of pediatric anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis. A total of 23 pediatric patients with anti-NMDAR encephalitis were included in the present study. The clinical data, laboratory test results, imaging examination, treatment outcomes, and follow-up records were reviewed and analyzed. A total of 8 patients exhibited prodromal symptoms, including fever, cough, and vomiting. Clinical symptoms included epilepsy, convulsions, ataxia, c...

Authors: Hao B, Chen X, Cao Y Abstract Yes-associated protein 1 (YAP1) is overexpressed in a number of human cancer types as an oncogene and takes part in processes of tumor cell proliferation, apoptosis and metastasis. The Notch pathway also has an important role in tumorigenesis and progression. However, the possible association between YAP1 and Notch signaling in glioma has remained to be determined. The present study verified the high expression of YAP1, Jagged 1 (JAG1), NOTCH1 and HES1 in the U251 glioma cell line via reverse-transcription quantitative polymerase chain reaction and western blot analysis. The e...

Previous studies have demonstrated that bone morphogenetic protein-7 (BMP7) gene transfer or mesenchymal stem cells (MSCs) transplantation may be a promising novel therapeutic approach. Therefore, the aim of the present study was to observe the effect of bone BMP7 transfer to MSCs on fracture healing. Bone marrow-derived MSCs (BMSCs) from New Zealand white rabbits were isolated and identified using flow cytometry. A recombinant BMP7 overexpressing adenovirus vector (Adv) was constructed and tran...

AbstractAttaching a cytotoxic “payload” to an antibody to form an antibody–drug conjugate (ADC) provides a mechanism for selective delivery of the cytotoxic agent to cancer cells via the specific binding of the antibody to cancer-selective cell surface molecules. The first ADC to receive marketing authorization was gemtuzu mab ozogamicin, which comprises an anti-CD33 antibody conjugated to a highly potent DNA-targeting antibiotic, calicheamicin, approved in 2000 for treating acute myeloid leukemia. It was withdrawn from the US market in 2010 following an unsuccessful confirmatory trial. The development of...
