Self-repairing cancer cells: A new pathway for cancer treatment

With narrow bodies and no collarbones, mice are able to squeeze through holes as small as a quarter-inch in diameter. Cancer cells similarly are able to migrate through extremely tight quarters but with a major difference: The journey often comes at a price - the deformation and, in some cases, rupture of the outer lining of a cell's nucleus. While deformation and rupture can sometimes lead to cell death, the cell - about 90 percent of the time - also has the ability to repair itself.

New research shows that autophagy can operate in cell nucleus to guard against start of cancer

Autophagy, literally self-eating or the degradation of unwanted cellular bits and pieces by the cell itself, has been shown for the first time to also work in the cell nucleus. In addition, in this setting it plays a role in guarding against the start of cancer, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

Researchers provide new insights into biology of aging, age-related diseases

The scientific team of a new biotech company Gero in collaboration with one of the leading academics in the field of aging Prof. Robert J. Shmookler Reis (current world record holder in life extension for model animals - 10 fold for nematodes) has recently brought new insights into biology of aging and age-related diseases, primarily, around the stability and stress resistance of certain gene regulatory networks.

Study offers new insights into construction of nuclear pores in nuclear envelope

In a recent study, a team of researchers led by Alwin Köhler at the Max F. Perutz Laboratories (MFPL) belonging to the University of Vienna and the Medical University of Vienna offer new insights into how nuclear pores are constructed in the nuclear envelope.

Study reveals how human genome is protected from inadvertent import of viral RNA into cell

Scientists of the Max F. Perutz Laboratories of the University of Vienna and the Medical University of Vienna, together with colleagues of the ETH Zurich, have now shown how double stranded RNA, such as viral genetic information, is prevented from entering the nucleus of a cell.

Professor receives $1.3M EUREKA grant to explore communication between cytoplasm and nucleus

University of Massachusetts Medical School Professor and Vice Chair of Neurobiology Vivian Budnik, PhD, has received a four-year, $1.3 million EUREKA (Exceptional Unconventional Research Enabling Knowledge Acceleration) grant from the National Institute of Neurological Disorders and Stroke to explore a novel mechanism of communication between the cytoplasm and the nucleus, called nuclear envelope budding, that may lead to new understandings for various tissue dystrophies and aging disorders.

Study shows disrupted micronuclei may prove to be a valuable tool for detecting cancer

Scientists studying cancer development have known about micronuclei for some time. These erratic, small extra nuclei, which contain fragments or whole chromosomes that were not incorporated into daughter cells after cell division, are associated with specific forms of cancer and are predictive of poorer prognosis.

Study offers new hope to patients suffering from laminopathies

Laminopathies are hereditary diseases that affect mainly the muscle tissue. These diseases include for example Emery-Dreifuss Muscular dystrophy, dilated cardiomyopathy, limb-girdle muscular dystrophy and Hutchison-Gilford progeria syndrome.

Stem cell study may help to unravel how genetic mutation leads to Parkinson's symptoms

By reprogramming skin cells from Parkinson's disease patients with a known genetic mutation, researchers at the Salk Institute for Biological Studies have identified damage to neural stem cells as a powerful player in the disease.

Lonafarnib clinical trial for progeria has scientific roots in basic biology discoveries

The good news widely reported this morning of positive results from a clinical drug trial at Boston Children's Hospital for the previously "untreatable" rapid aging disorder in children known as progeria has its scientific roots in basic biology discoveries made in recent years.

New research sheds light on pluripotency

New research at the Hebrew University of Jerusalem sheds light on pluripotency-the ability of embryonic stem cells to renew themselves indefinitely and to differentiate into all types of mature cells.

RNP granules exit the nucleus via new budding mechanism akin to herpes-type viruses

New evidence published in Cell by Vivian Budnik, PhD, Melissa J. Moore, PhD, and colleagues at the University of Massachusetts Medical School, reveals a novel budding mechanism, similar to the process used by some viruses, capable of exporting large ribonucleoprotein particles from the nucleus to the cytoplasm.

Researchers use baker's yeast to gain insight into chromosome separation process

Researchers at the Stowers Institute for Medical Research used, ironically enough, the single-celled organism Saccharomyces cerevisiae -- commonly known as baker's yeast -- to gain new insight into the process by which chromosomes are physically segregated during cell division.

Scientists identify mechanism that regulate nuclear size

Size matters when it comes to the nucleus of a cell, and now scientists have discovered the signals that control how big the nucleus gets. Nuclear size varies not only among different species, but also in different types of cells in the same species and at different times during development. In addition, cancer cells are known to develop larger nuclei as they become more malignant. Screening for cervical cancer, for example, involves looking for grossly distorted nuclei in cervical cells collected during a Pap smear.

Research on OGF-OGFr complex helps to understand pathobiology of diseases

Researchers at The Pennsylvania State University College of Medicine, Hershey, Pennsylvania have discovered that the Opioid Growth Factor (OGF, [Met5]-enkephalin) and its receptor, OGFr, a clinically important system with potent antitumor properties, has controlled entry from the cytoplasm to the nucleus. The nucleocytoplasmic passage of OGF-OGFr is critical to cell proliferation and suggests that there are hierarchical levels of nuclear import.
