Cancer begins in your cells, which are the building blocks of your body. Normally, your body forms new cells as you need them, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should. These extra cells can form a mass called a tumor. Tumors can be benign or malignant. Benign tumors aren't cancer while malignant ones are. Cells from malignant tumors can invade nearby tissues. They can also break away and spread to other parts of the body.
Researchers at Hiroshima University have analyzed the molecular findings of almost 160 pediatric liver cancer cases and discovered molecular markers that should help to understand and treat the considerable variation in prognoses.
A Cleveland Clinic-led research team found that statistically overweight children who followed a healthy eating pattern significantly improved weight and reduced a variety of cardiovascular disease risks.
Are prematurely aged or overworked stem cells a significant factor in chronic lung disease? Findings of a study just released in STEM CELLS Translational Medicine (SCTM) say this is likely so.
At more than 2 meters long, the human DNA molecule uses intricate folding patterns to fit into cells while locally unfolding to express genes. Such phenomena, however, are difficult to measure in experiments, and theoretical frameworks explaining them continue to be at odds with one another.
Time-released drugs are about to get a geometry lesson, thanks to bioengineers at Rice University.
Bacon could be back on the menu of health-conscious diners thanks to an unlikely salvation: Japanese knotweed.
Cold Spring Harbor Laboratory Press (CSHLP) announced the release of T-Cell Memory, available on its website in hardcover and eBook formats.
In human cancer cell and mouse studies, researchers from Johns Hopkins Medicine have found that a set of proteins work in tandem to build supply lines that deliver oxygen and nutrients to tumors, enabling them to survive and grow.
Malignant tumors can enhance their ability to survive and spread by suppressing antitumor immune cells in their vicinity, but a study led by researchers at Weill Cornell Medicine and NewYork-Presbyterian has uncovered a new way to counter this immunosuppressive effect.
Experimental biologists are experimenting with light to activate mechanisms within genetically modified fission yeast cells.
Recently, scientists created an automated computer program that can precisely and reproducibly count micronuclei from microscope images.
Scientists at St. Jude Children's Research Hospital have revealed how the tumor suppressor gene PTEN plays a more important role in pediatric rhabdomyosarcoma than was previously appreciated.
Immunotherapy is an advancing field but there is limited knowledge on the immunity to metastatic tumors in locations like lymph nodes.
Over the past decade, scientists have been exploring vaccination as a way to help fight cancer. These experimental cancer vaccines are designed to stimulate the body's own immune system to destroy a tumor, by injecting fragments of cancer proteins found on the tumor.
Researchers at Université de Montréal and McGill University have discovered a new multi-enzyme complex that reprograms metabolism and overcomes “cellular senescence,” when aging cells stop dividing.
Hundreds of cancer-linked genes play a different role in causing disease than scientists had expected.
A team of researchers recently postulated a genetic classifier with the ability to predict the sensitivity of neoadjuvant chemotherapy for breast cancer in the area of tumor molecular markers.
Recent research revealed the chemical steps in a vital cellular modification mechanism that inserts a chemical tag to certain RNAs. Interference of this process in humans can result in cancers, diabetes, and neuronal diseases.
Gliomas are the most common primary brain tumors in adults. Among them, high-grade glioblastomas (GBMs) are particularly known to be notoriously aggressive and invasive, which makes it challenging to treat them.
Ginseng, a widely popular superfood, has long been used in traditional medicine. The health benefits of ginseng are largely attributed to compounds called ginsenosides, which are present in the roots, stems, and leaves of the plant. Ginsenosides are known to prevent inflammation, diabetes, and cancer, and can also help control blood cholesterol levels and reduce aging.
