Researchers develop breakthrough in marine sponge cell culture

Vertebrate, insect, and plant cell lines are important tools for research in many disciplines, including human health, evolutionary and developmental biology, agriculture and toxicology. Cell lines have been established for many organisms, including freshwater and terrestrial invertebrates.

Impaired gene expression may influence aging via altered cellular metabolism

Throughout history, humans have been obsessed with finding a way to prevent aging and prolong life. Although the mechanisms have long eluded us, modern science is revealing more and more about the aging process. Now, researchers from Japan have uncovered new information about the genetic processes that may trigger age-related disorders, including low energy production and low cellular growth.

Circular DNA found in cancer cells supports their survival and resistance

A new study uncovers the role of the circular, 3D shape of extrachromosomal DNA in augmenting mutant oncogenes in cancer cells.

Scientists develop new therapy for acute myeloid leukemia

Cold Spring Harbor Laboratory scientists, with chemists and cancer biologists from Dana-Farber Cancer Institute, have developed a new therapy that extended the survival of mice with acute myeloid leukemia.

Potential new therapy for progeria

Aging is a complex and natural process that affects all living organisms. As people age, normal biological processes are affecting, resulting in a decline in various organs and age-related conditions. Though aging is normal, some children affected by a disease called Progeria may age way faster than others.

New way to promote insulin production in pre-diabetes phase discovered

Nanyang Technological University, Singapore scientists have discovered that a type of immune cell known as 'pancreatic islet macrophages' is capable of promoting insulin production during the pre-diabetes phase.

Study sheds light on how Zika virus causes microcephaly in newborns

A new study led by researchers at Baylor College of Medicine revealed how in utero Zika virus infection can lead to microcephaly in newborns. The team discovered that the Zika virus protein NS4A disrupts brain growth by hijacking a pathway that regulates the generation of new neurons.

Scientists find driver for more deadly prostate cancer

A transcription factor that aids neuron function also appears to enable a cell conversion in the prostate gland that can make an already recurrent cancer even more deadly, scientists say.

Mechanisms preserving cell identity are based on status of proteins housing DNA

The inheritance, not only of DNA, but of changes to proteins that package it, maintains the identity of cells as they multiply, a new study finds.

Chemotherapy-induced senescent cells eat neighboring cells

A new study has found that chemotherapy-induced senescent cancer cells feed on other neighboring cells to enhance their survival.

Some types of proteins can stabilize damaged DNA

At the University of Copenhagen, researchers have discovered how some types of proteins stabilize damaged DNA and thereby preserve DNA function and integrity. This new finding also explains why people with inborn or acquired defects in certain proteins cannot keep their DNA stable and develop diseases such as cancer.

Scientists uncover how brain cells respond to and recover from lack of nutrition

We all know that food is essential to healthy development of the brain and body, especially in the earliest stages of life. But exactly how early brain growth is affected by nutrition is not as well understood, especially on a cellular level.

Novel agent reduces buildup of toxic proteins in Parkinson's and Alzheimer's animal models

Neuroscientists at Georgetown University Medical Center say they have developed and tested an agent that reduces the buildup of toxic proteins in animal models of both Parkinson's and Alzheimer's diseases, and improves cognitive and motor behavior.

Newly discovered organelle could help prevent cancer

Scientists at the University of Virginia School of Medicine have discovered a strange new organelle inside our cells that helps to prevent cancer by ensuring that genetic material is sorted correctly as cells divide.

Johns Hopkins researchers document lower cell replication rates in old age

In a novel study comparing healthy cells from people in their 20s with cells from people in their 80s, researchers at the Johns Hopkins Kimmel Cancer Center say they have documented that cell division rates appear to consistently and markedly slow down in humans at older ages.

Study shows why fatty liver disease contributes to increase in liver cancer

Fatty liver disease is contributing to an increase in liver cancer and basic scientists at The University of Texas Health Science at Houston have new insight as to why.

Researcher explores biological processes that cause fertility problems in humans

With significant funding from the National Institutes of Health (NIH), a researcher at The University of Texas at Arlington is investigating fundamental biological processes that lead to fertility problems in humans.

Structural biology reveals 3D structure of asthma-linked receptor

A new study has laid bare the structure of a protein receptor called the CysLT1 receptor that is implicated in a range of allergic and cardiovascular conditions as well as some types of cancer. Published in Science Advances, the paper shows how the researchers used structural biology techniques to accomplish this feat.

β-blockers could regenerate infant heart muscle, mitigate effects of congenital heart disease

Surgery can mend congenital heart defects shortly after birth, but those babies will carry a higher risk of heart failure throughout the rest of their lives. Yet, according to a Science Translational Medicine study published today by UPMC Children's Hospital of Pittsburgh researchers, β-blockers could supplement surgery to regenerate infant heart muscle and mitigate the lasting effects of congenital heart disease.

New understanding of breast cancer metastasis to bone

In breast cancer patients with metastatic disease, bone is the most common site of metastasis and the most common site of first distant relapse, with roughly half (48%) of breast cancer patients developing bone metastases after treatment.
