Neural regulation of drug resistance in cancer treatment

Publication date: Available online 9 November 2018Source: Biochimica et Biophysica Acta (BBA) - Reviews on CancerAuthor(s): Dan Liu, Xiaoxi Li, Xintian Chen, Yu Sun, Anqun Tang, Zhongwei Li, Junnian Zheng, Ming ShiAbstractThe treatment of cancer has made great progress. However, drug resistance remains problematic. Multiple physiologic processes of tumor development can be dominated by central and sympathetic nervous systems. The interactions between the nervous system, immune system, and tumor occur consistently and dynamically. Recent evidence suggests that nerves and neural signals are intimately involved in the development of resistance to cancer therapies. In this review, we will provide an overview of the recent progress in this rapidly growing area and discuss the potential new strategies for targeting the neural signaling pathway to improve the effectiveness of chemotherapies, targeted therapies, and immunotherapies.

Publication date: Available online 3 December 2019Source: Pharmacological ResearchAuthor(s): Carlo Fumagalli, Niccolò Maurizi, Niccolò Marchionni, Diego FornasariAbstractThe pharmacological class of β-blockers includes a plea of molecules with largely different pharmacokinetic and pharmacodynamic characteristics with a protective effect that may span far beyond the cardiovascular system. Although all these compounds share the pharmacological blockade of the adrenergic receptors, each of them is characterized by specific pharmacological properties, including selectivity of action depending on the adrenerg...

Human papillomavirus (HPV) genotyping for HPV-16 and HPV-18, followed by reflex cytological testing in women with positive results, is more likely than cytological testing alone to detect cervical intraepithelial neoplasia (CIN) grade 2 or higher, according to results from the FRIDA study.Reuters Health Information

This study aimed to analyze the clinical safety and effectiveness of endoscopic ultrasound-guided celiac plexus neurolysis (EUS-CPN) in alleviating intractable abdominal pain caused by advanced pancreatic cancer. A total of 58 patients with inoperable pancreatic cancer who underwent EUS-CPN from May 2015 to December 2017 were enrolled. Pain levels before and after EUS-CPN were assessed and compared using the Visual Analogue Scale. The preoperative Visual Analogue Scale score was 8.2±2.3, which decreased significantly to 3.6±1.5 at 2 days after EUS-CPN and to 2.2±0.8 after 1 month. The response rate was...

AbstractOf all genetic mutations causing human disease, premature termination codons (PTCs) that result from splicing defaults, insertions, deletions, and point mutations comprise around 30%. From these mutations, around 11% are a substitution of a single nucleotide that change a codon into a premature termination codon. These types of mutations affect several million patients suffering from a large variety of genetic diseases, ranging from relatively common inheritable cancer syndromes to muscular dystrophy or very rare neuro-metabolic disorders. Over the past three decades, genetic and biochemical studies have revealed t...

This study demonstrates for the first time that senescent cells secrete functional LTs, significantly contributing to the LTs pool known to cause or exacerbate idiopathic pulmonary fibrosis. Against Senolytics https://www.fightaging.org/archives/2019/11/against-senolytics/ There is no consensus in science that is so strong as to have no heretics. So here we have an interview with a naysayer on the matter of senolytic treatments, who argues that the loss of senescent cells in aged tissues will cause more harm to long-term health than the damage they will do by remaining. To be clear, I think this to be a ...

Dogs are an interesting species when it comes to the study of aging. Firstly they are much closer to human metabolism and cellular biochemistry than mice, and secondly selective breeding has generated lineages with a very wide range of sizes and life spans. Thirdly, they occupy a good compromise position in the range of life spans, study cost, and similarity to humans. Mice live short lives, so studies are rapid and comparatively cheap, but there are sizable, important differences between mouse and human biochemistry. Humans live so long that most studies of aging are simply out of the question. Even in non-human primates ...

Catecholamines released by sympathetic nerves can activate adrenergic receptors present on nearly every cell type, including myeloid-derived suppressor cells (MDSCs). Using in vitro systems, murine tumor models in wild-type and genetically modified (β2-AR–/–) mice, and adoptive transfer approaches, we found that the degree of β2-AR signaling significantly influences MDSC frequency and survival in tumors and other tissues. It also modulates their expression of immunosuppressive molecules such as arginase-I and PD-L1 and alters their ability to suppress the proliferation of T cells. The regulatory funct...

Mounting preclinical and clinical evidence continues to support a role for the neuroendocrine system in the modulation of tumor biology and progression. Several studies have shown data supporting a link between chronic stress and cancer progression. Dysregulation of the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis has been implicated in promoting angiogenesis, tumor cell proliferation and survival, alteration of the immune response and exacerbating inflammatory networks in the tumor microenvironment. Here, we review how SNS and HPA dysregulation contributes to disturbances in immune ce...
