Researchers identify molecule that could aid lung cancer detection, treatment

According to the National Cancer Institute (NCI), lung cancer is the leading cause of cancer death among both men and women in the United States, and 90 percent of lung cancer deaths among men and approximately 80 percent of lung cancer deaths among women are due to smoking. The NCI also estimates that approximately 373,489 Americans are living with lung cancer and its treatment costs approximately $10.3 billion in the United States each year…

Novel mutations define two types of bone tumor: Two related genes underlie the development of two rare bone tumors in nearly 100 per cent of patients

These mutations are found in nearly 100 per cent of patients suffering from two rare bone tumours; chondroblastoma and giant cell tumour of the bone. Chondroblastoma and giant cell tumour of bone are benign bone tumours that primarily affect adolescents and young adults, respectively. They can be extremely debilitating tumours and recur despite surgery…

A cost-effective way toward personalized cancer drugs

In treating many types of cancer, doctors often use combi-nation of chemotherapy with other treatments. The cytostatic agents used are designed to target faster growing cancer cells. But there is little consistency in how different patients respond to the various treatments: even when dealing with the same type of tumor, there are vast differences in tumor cell reaction to a given treatment…

Review of daily aspirin dosage highlights concerns about side effects

The possible benefits of a daily dose have been promoted as a primary prevention for people who are currently free of, but at risk of developing, cardiovascular disease or colorectal cancer. However, any such benefit needs to be balanced alongside a fuller understanding of the potentially harmful side effects such as bleeding and gastrointestinal problems. The paper, published by the National Institute for Health Research Health Technology Assessment (NIHR HTA) Programme, reviews the wealth of available randomised controlled trials (RCTs), systematic reviews and meta-analyses, allowing the team from Warwick Evidence to quantify those relative benefits and risks. The reported benefits of taking aspirin each day ranged from 10% reduction in major cardiovascular events to a 15% drop in total coronary heart disease. …

Physicists decode decision circuit of cancer metastasis

The study appears online this week in the Early Edition of the Proceedings of the National Academy of Sciences. "Cancer cells behave in complex ways, and this work shows how such complexity can arise from the operation of a relatively simple decision-making circuit," said study co-author Eshel Ben-Jacob, a senior investigator at Rice’s Center for Theoretical Biological Physics (CTBP) and adjunct professor of biochemistry and cell biology at Rice. "By stripping away the complexity and starting with first principles, we get a glimpse of the ‘logic of cancer’ — the driver of the disease’s decision to spread." In the PNAS study, Ben-Jacob and CTBP colleagues José Onuchic, Herbert Levine, Mingyang Lu and Mohit Kumar Jolly describe a new theoretical framework that allowed them to model the behavior of microRNAs in decision-making circuits…

Stealth nanoparticles lower drug-resistant tumors’ defenses

Paula T. Hammond and colleagues at the Koch Institute of Integrative Cancer Research at MIT note that triple-negative breast cancer (TNBC) is an aggressive disease that is difficult to treat with standard-of-care therapy, and patients’ prognoses are poor. These cancer cells evade treatment by ramping up the production of certain proteins that protect tumors from chemotherapy drugs…
