Lung cancer is still the leading cause of cancer-related mortality worldwide. According to the CDC, smoking cigarettes is linked to 80-90% of lung cancer deaths in the United States. In non-smokers, lung cancer can be caused by exposure to radon, secondhand smoke, air pollution, asbestos, diesel exhaust, and other chemicals and factors. 

Some symptoms of lung cancer include pain in chest or ribs, frequent respiratory infections, shortness of breath, wheezing, fatigue or loss of appetite. As numerous research studies about lung cancer are currently underway, we hope this Special Collection will set future research in motion to discover more causes and treatments for this disease.

Special Collections: Lung Cancer

Oncotarget publishes open access peer-reviewed literature about research studies, clinical studies, reviews, case reports, and meta-analyses on a variety of different topics pertaining to cancer. Lung cancer continues to be an area of interest for researchers, therefore, the Special Collection on Lung Cancer was created by Oncotarget for scientists and researchers to discover new biomarkers, mechanisms, and therapies to treat this cancer.

All content submitted for publication has been reviewed by a diligent board of academic editors and world-renowned scientists and researchers. In this Special Collection, the content focussing on lung cancer is organized together in one place, including papers such as “Molecular pathways and therapeutic targets in lung cancer” by Emma Shtivelman, Thomas Hensing, George R. Simon, Phillip A. Dennis, Gregory A. Otterson, Raphael Bueno, and Ravi Salgia. This review is a summary of the pathways and mechanisms involved in current treatment methods for lung cancer of various types.

This meta-analysis examines the relationship between exposure to PM2.5 (particulate matter or fine particles) and lung cancer incidence and mortality: “Relationship between exposure to PM2.5 and lung cancer incidence and mortality: A meta-analysis” by Feifei Huang, Bing Pan, Jun Wu, Engeng Chen, and Liying Chen.

This review focuses on improved anticancer agents and therapy options for lung cancer patients with acquired EGFR TKI (chemotherapy) resistance: “Clinical strategies for acquired epidermal growth factor receptor tyrosine kinase inhibitor resistance in non-small-cell lung cancer patients” by Lijun Dong, Dan Lei, and Haijun Zhang.

As you may know, Oncotarget is a scientific journal that publishes oncology-focused review and research papers every week on its open access platform — available at no cost to readers. Recently, a new Special Collections series debuted, and the first collection launched in honor of breast cancer awareness.

What makes our collections special? 

Oncotarget carefully selects the most credible and insightful studies to publish on Oncotarget.com, while also choosing papers that link different fields of oncology, cancer research, and biomedical sciences together to eliminate borders between specialties. The term “oncotarget” encompasses all molecules, pathways, cellular functions, cell types, and tissues that can be viewed as targets relevant to cancer, as well as other diseases. This journal is a resource for oncology researchers and the larger scientific community.

Before a study is published in Oncotarget, selected papers are meticulously peer-reviewed by an editorial board of award-winning scientific editors from academic universities and institutions well-known for their excellence and precision.

Breast cancer research

Each year, over 40,000 women and men lose the fight against breast cancer in the United States. After skin cancer, breast cancer is the most commonly diagnosed cancer in women. The spread of breast cancer awareness and increase in research funding has helped develop advances and discoveries in the diagnosis and treatment of this proliferous cancer. 

The new Special Collections by Oncotarget are yet another tool researchers and science readers alike may use as a resource to learn more about breast cancer. The creators of these collections also hope that they may be used by scientists to discover new biomarkers, mechanisms, and therapies to improve our quality of life and better treat cancer and diseases.

Thanks to Impact Journals, we know exercise helps to fight breast cancer—for free

oncotarget

A recent breakthrough medical study has revealed that exercise has been proven to combat breast cancer.  The paper, entitled “Anticancer effect of physical activity is mediated by modulation of extracellular microRNA in blood,” was recently published in a June 2020 issue of the free online open-access medical journal Oncotarget. It was authored by an international team of medical researchers, headed by Dr. Alessandra Pulliero of the University of Genoa in Italy, and included Doctors Ming You, Pradeep Chaluvally-Raghavan, Barbara Marengo, Cinzia Domenicotti, Barbara Banelli, Paolo Degan, Luigi Molfetta, Fabio Gianiorio, and Alberto Izzotti.

The paper has already received widespread acclaim and coverage, reproduced online by prestigious organizations such as the National Center for Biotechnology Information (a branch of the U.S. National Institutes of Health), the American Association for the Advancement of Science, and ResearchGate.

THE STUDY

While previous medical studies have shown that physical activity reduces the risk of cancer, particularly breast cancer, it’s been a mystery up to now exactly how this happens. Medical researchers have long suspected that this healing process is triggered by microRNAs, cellular fragments of RNA (ribonucleic acid) also known as miRNAs.

What’s RNA? Like DNA (deoxyribonucleic acid), RNA is one of the building blocks of life. It acts as a messenger transmitting instructions that control the synthesis of proteins. MicroRNAs stop a particular protein from being produced by binding to, and then destroying, the messenger RNA that would have produced this protein.

It is known that miRNAs are incredibly important when it comes to carcinogenesis (the creation of cancer) and cancer outcomes. In addition, MiRNAs regulate the creation of muscle tissueand muscle mass, and it’s been learned that structured exercise controls the creation of miRNA, especially in skeletal muscle.

The research team endeavored to test how exercise in breast cancer patients changed the production of miRNA in their bodies. To begin, 30 women from northern Italy between 54 and 78 years old walked for 45 minutes on the treadmill under identical conditions. Blood samples were taken from them both before and after the exercise sessions.

THE RESULTS

A technique known as microarray analysis revealed that structured exercise modified 14 different extracellular miRNAs related to cancer. Structured exercise caused all these miRNAs to decrease, except for a miRNA called miR-206, which increased. The researchers discovered that the most striking effects induced by exercise were changes in two miRNAs involved in breast cancer progression.

When the researchers investigated the biological effects of these two miRNAs on human breast cancer cells, they conclusively learned that working together, the changes in these two microRNAs activated by a physical exercise program suppressed breast cancer cells. Since too many miRNAs are linked to triggering inflammation and the creation of lymphocytes (white blood cells in the lymph system, which can influence breast cancer), the researchers also believe that structured exercise might reduce inflammation by modulating miRNA in the blood.

They also found that structured exercise improved blood pressure and glucose levels (cancerous tumors feed on glucose) among participants. The doctors discovered that these improvements in blood pressure and glucose levels helped regulate the miRNAs being studied, and in turn helped the miRNAs combat cancer.

This international team of researchers is confident that by testing for the levels of these miRNAs in patients’ blood, they’ve achieved a non-invasive way of establishing biomarkers (a measurable sign of whether a disease is present or how severe it is) to prevent breast cancer. This is potentially a significant breakthrough in breast cancer prevention and treatment.

As a result of this study, the medical community now knows that structured exercise fights breast cancer, and it’s been given a non-invasive way to diagnose and battle breast cancer—and possibly other forms of cancers as well.
