Swarms of magnetic bacteria could be used to deliver drugs to tumors

One of the biggest challenges in cancer therapy is being able to sufficiently deliver chemotherapy drugs to tumors without exposing healthy tissues to their toxic effects. Magnetic bacteria are a promising vehicle for more efficiently delivering tumor-fighting drugs, researchers have demonstrated.

RenovoRx said today that it closed a $7 million tranche in a $10 million round to fund the development of its drug-device combination product designed to deliver chemotherapy directly to tumors in patients with locally advanced pancreatic cancer. The company’s round was led by Boston Scientific (NYSE:BSX) and joined by btov Partners, Astia Angels, Golden Seeds and others. Get the full story at our sister site, Drug Delivery Business News.

Senolytic compounds are those capable of selectively destroying senescent cells. They are useful because the buildup of senescent cells over time is one of the root causes of aging. A number of mechanisms have been discovered by which senescent cells can be provoked into self-destruction, such as bcl-2 inhibition or interference in FOXO4-p53 interactions. These examples are fairly well understood. Other mechanisms are known but less well understood; they require more work in order to proceed on the production of improved senolytic compounds. In some cases, however, the primary mechanism of action of a compound found...

Authors: Aqbi HF, Tyutyunyk-Massey L, Keim RC, Butler SE, Thekkudan T, Joshi S, Smith TM, Bandyopadhyay D, Idowu MO, Bear HD, Payne KK, Gewirtz DA, Manjili MH Abstract Breast cancer patients who initially respond to cancer therapies often succumb to distant recurrence of the disease. It is not clear why people with the same type of breast cancer respond to treatments differently; some escape from dormancy and relapse earlier than others. In addition, some tumor clones respond to immunotherapy while others do not. We investigated how autophagy plays a role in accelerating or delaying recurrence of neu-overexpressing...

In this study, we evaluated the feasibility of visible light-cured glycol chitosan (GC) hydrogels with controlled release of doxorubicin⋅hydrochloride (DOX⋅HCl) as local DDSs for effective cancer therapy in vivo. The storage modulus of the hydrogel precursor solutions was increased as a function of visible light irradiation time. In addition, the swelling ratio of the hydrogel irradiated for 10 s (GC10/DOX) was greater than in 60 s (GC60/DOX). In vitro release test showed that DOX was rapidly released in GC10/DOX compared with GC60/DOX due to the density of cross-linking. In vitro and in vivo tests ...

CONCLUSION: NDRG1 is an important modulator linking DNA damage response and hypoxia-related cellular stress response during the development of drug resistance to cisplatin/CMNa in lung cancer. Targeting both NDRG1 and ERCC1 may be a viable strategy for overcoming drug resistance in cancer therapy, and has significant clinical implications. PMID: 29768183 [PubMed - as supplied by publisher]

Authors: Li G, Liang Y, Sun C, Peng X, Hao N, Liu M, Gao W, Wu H, He B Abstract Percutaneous ethanol injection (PEI) therapy was used in liver cancer treatment, however, the therapeutic ethanol in PEI easily flew away from injected solid tumours and hinder the treatment effect. In this paper, injectable supramolecular gels formed by self-assembly of low molecular weight gelators (LMWGs) based on glycylglycine modified phenylboronic acid were prepared to localize ethanol and load chemotherapeutic drug for in situ synergistic therapy. The mechanism, morphology and rheological property of supramolecular gels were char...

CONCLUSIONS: The significant improvement in the physical well-being is attributed to the eradication of symptoms, whereas the relevant improvements in the emotional wellbeing subscale are explained both by the pre-operative desperation of the diagnosis or relapse of malignancy, and the post-operative hopefulness after a successful operation.

This study aimed to evaluate long‐term cognitive functioning (CogF) in germ‐cell tumor (GCT) survivors.Subjects, Materials, and Methods.GCT survivors (n = 155) from the National Cancer Institute of Slovakia completed the Functional Assessment of Cancer Therapy Cognitive Function at a median of 10 years of follow‐up (range: 5–32). The study group consisted of survivors receiving a cisplatin‐based chemotherapy, radiotherapy to the retroperitoneal lymph nodes, or both, whereas the control group included survivors treated with orchiectomy only.Results.Of the total survivors, 138 received treatment b...

Authors: Zhang L, Chen H, Wang M, Song X, Ding F, Zhu J, Li X Abstract Gastric cancer most commonly occurs in East Asia, and China accounts for more than half the of world's gastric cancer burden. Despite the efficacy of chemotherapy for patients, this treatment leads to significant patient inconvenience, toxicity and cost. The present study aimed to assess a non-toxic agent, glabridin, as a future chemotherapeutic approach for treating gastric cancer. Using cell proliferation, apoptosis, invasion, and colony formation assays, it was determined that glabridin alone, or in combination with 5-fluorouracil (5-FU), inh...
