UTA leads project to develop new device to deliver photo-induced cancer therapy

(University of Texas at Arlington) Physicists from the University of Texas at Arlington are leading a multidisciplinary project with the University of Texas Southwestern Medical Center in Dallas and the University of Texas MD Anderson Cancer Center in Houston to develop a new multifunctional platform that can integrate imaging and photo-induced cancer therapy in a single, portable device.

In this study, we have further investigated the anti-tumor effects of D5D-knockdown and the resulting intensified COX-2-catalyzed DGLA peroxidation in subcutaneous xenograft tumors. Four-week old female nude mice (Jackson Laboratory, J:Nu-007850) were injected with human pancreatic cancer cell line BxPC-3 or its D5D knockdown counterpart (via shRNA), followed by 4-week treatments of: vehicle control, DGLA supplementation (8 mg/mouse, twice a week), gemcitabine (30 mg/kg, twice a week), and a combination of DGLA and gemcitabine. In D5D-knockdown tumors, DGLA supplementation promoted 8-HOA formation to a threshold ...

Publication date: 15 February 2019Source: Chemical Engineering Journal, Volume 358Author(s): Wei Zhu, Li Zhang, Zhe Yang, Pei Liu, Jing Wang, Jinguo Cao, Aiguo Shen, Zushun Xu, Jing WangAbstractThough imaging guided photodynamic therapy (PDT) has emerged as a promising cancer therapy, how to enhance the PDT efficiency is still a research hotpot due to the tumor hypoxia and insufficient dosage of photosensitizers in the tumor site. Herein, a multifunctional theranostic nanoplatform was rationally constructed by nanoscale metal organic frameworks (NMOFs), bovine serum albumin (BSA), sulfadiazines (SDs), and MnO2. Porphyrin a...

AbstractPurpose of ReviewAs the modern era of cancer treatment improves survival for patients, intensive care units (ICUs) play an increasing role in their management to support patients during cancer therapy. This review seeks to summarise some important changes and persisting challenges in the care of this complex patient group.Recent FindingsTechnological advances and improvements in overall cancer treatment have challenged historical approaches to suitability for admission and provision of ICU support. In particular, old paradigms (such as not admitting hematological malignancy patients to the ICU for mechanical ventil...

Abstract The field of cancer immunology stepped into the limelight this year when James P. Allison and Tasuku Honjo received the Nobel Prize in Physiology or Medicine for their discovery of cancer therapy by inhibition of negative immune regulation. Among many exciting advances contributing to the coming of age of tumour immunology as a viable clinical specialty has been the ability to progress from the initial elucidation of tumour antigens, such as the melanoma antigen, MAGE-1, to high-throughput sequencing facilitating identification of T cell epitopes from diverse tumour neoantigens. This has resulted from the...

AbstractPurposeThis observational study was designed to measure baseline energy parameters and body composition in early-stage breast cancer patients, and to follow changes during and after various modalities of treatment. This will provide information to aid in the development of individualized physical activity intervention strategies.MethodsPatients with newly diagnosed stage 0 –III breast cancer were enrolled into three cohorts: A (local therapy alone), B (endocrine therapy), or C (chemotherapy with or without endocrine therapy). At baseline, 6 months, and 12 months, subjects underwent a stationary bicy...

Malignant pleural mesothelioma (MPM) is a rare tumor principally due to past exposure to asbestos, a carcinogenic natural mineral fiber that induces genomic and genetic alterations [1]. Lack of curative treatment due to resistance to anti-cancer therapies combined with tumor aggressiveness accounts for the poor prognosis associated to MPM. Despite the significant advances in oncotherapy, MPM is still a challenging cancer to treat [2].

Fragile histidine triad (FHIT) serves a critical function as a tumor suppressor that inhibits p53 degradation by mouse double minute 2 (MDM2). The functional domains of FHIT involved in tumor inhibition was interpreted. In-silico screening data were employed to construct truncated forms of FHIT to assess their cytotoxic effects on the HT1080 cell line. Full FHIT expression was confirmed by western blotting and expression of two FHIT truncates were confirmed by RT-PCR. Transfection of these truncated forms into HT1080 cells showed that the N-terminal truncated form (amino acids 17-102) better inhibited proliferation than t...

I think it is entirely appropriate to greet the advent of senolytics with enthusiasm. These treatments are the first legitimate rejuvenation therapies to successfully target one of the root causes of aging, the accumulation of lingering senescent cells in old tissues. The first human trial data is approaching publication, but even before it arrives, the evidence to date strongly suggests that meaningful levels of rejuvenation can be achieved in old people at a very low cost. The first senolytic drugs (such as dasatinib and navitoclax) and plant extracts (such as fisetin and piperlongumine) cost very little, and remove only...
