Researchers identify new gene in Cornelia deLange syndrome

Genetics researchers have identified a key gene that, when mutated, causes the rare multisystem disorder Cornelia deLange syndrome (CdLS). By revealing how mutations in the HDAC8 gene disrupt the biology of proteins that control both gene expression and cell division, the research sheds light on this disease, which causes intellectual disability, limb deformations and other disabilities resulting from impairments in early development.

New class of drugs reduces adverse effects of cellular damage from cancer chemotherapy

Chemotherapy kills tumor cells, but it also wreaks havoc on the rest of the body. A team of researchers led by Igor Roninson of the South Carolina College of Pharmacy just reported the discovery of a new class of drugs that reduces the adverse effects of cellular damage from chemotherapy.

Mammalian cells divide when their growth rate hits a specific threshold

It's a longstanding question in biology: How do cells know when to progress through the cell cycle? In simple organisms such as yeast, cells divide once they reach a specific size. However, determining if this holds true for mammalian cells has been difficult, in part because there has been no good way to measure mammalian cell growth over time.

Researchers identify how telomerase is recruited to chromosome ends

Stem cells are special. Nestled in muscle and skin, organ and bone, they bide their time over years or decades until called to replace damaged or lost tissue. One secret to their longevity is an enzyme called telomerase, which stills the relentless ticking of the molecular clock that limits the life span of other cells.

Orc1 mutations may explain pathology in manifestations of Meier-Gorlin syndrome

Research published Aug. 1 by scientists at Cold Spring Harbor Laboratory (CSHL) links gene mutations found in some patients with Meier-Gorlin syndrome (MGS) with specific cellular dysfunctions that are thought to give rise to a particularly extreme version of dwarfism, small brain size, and other manifestations of abnormal growth which generally characterize that rare condition.

TAU researcher reveals link between plant and human biology

Increasingly, scientists are uncovering surprising biological connections between humans and other forms of life. Now a Tel Aviv University researcher has revealed that plant and human biology is much closer than has ever been understood - and the study of these similarities could uncover the biological basis of diseases like cancer as well as other "animal" behaviors.

Scientists uncover how internal mechanisms in nerve cells wire the brain

Scientists at the University of Manchester have uncovered how the internal mechanisms in nerve cells wire the brain. The findings open up new avenues in the investigation of neurodegenerative diseases by analysing the cellular processes underlying these conditions.

Internal clock of human skin responsible for time-based steering of repair and regeneration

A research team at Charité - Universitätsmedizin Berlin together with scientists at a company in Hamburg has now discovered that human skin has an internal clock responsible for the time-based steering of its repair and regeneration, among other things. The team published its first results from their basic research in the current issue of Proceedings of the Academy of Science (PNAS).

Study helps explain why leukemia occurs more frequently as people age

Hundreds of mutations exist in leukemia cells at the time of diagnosis, but nearly all occur randomly as a part of normal aging and are not related to cancer, new research shows.

Combination of Dox with MCP shows promise against prostate cancer

Doxorubicin (Dox) is an effective anti-cancer drug, but it's also a very toxic one, causing severe heart and immune damage. The doses needed to impact tumors are not well tolerated by patients, however, researchers may have found an answer through combination therapy.

Targeting CDK1 pathway may be efficacious for acute myeloid leukemias with FLT3 mutation

Acute myeloid leukemia, a common leukemia in adults, is characterized by aberrant proliferation of cancerous bone marrow cells. Activating mutations in a protein receptor known as FLT3 receptor are among the most prevalent mutations observed in acute myeloid leukemias. FLT3 mutants are thought to activate several signaling pathways that contribute to cancer development.

Ajuba protein plays a central role in regulating function of heart stem cells

It is not unusual for babies to be born with congenital heart defects. This is because the development of the heart in the embryo is a process which is not only extremely complex, but also error-prone. Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim have now identified a key molecule that plays a central role in regulating the function of stem cells in the heart.

Cellular change also occurs in early-stage lung cancer, say researchers

Cellular change thought to happen only in late-stage cancers to help tumors spread also occurs in early-stage lung cancer as a way to bypass growth controls, say researchers at Mayo Clinic in Florida.

Study details how resistance to targeted drug therapy emerges in colorectal cancers

A Harvard researcher studying the evolution of drug resistance in cancer is predicting that, in a few decades, "many, many cancers could be manageable."

DRCRF names 21 new Damon Runyon Fellows

The Damon Runyon Cancer Research Foundation, a non-profit organization focused on supporting innovative early career researchers, named 21 new Damon Runyon Fellows at its spring Fellowship Award Committee review.

Researchers discover mechanism that favours disappearance and inhibition of SCC development

Skin squamous cell carcinoma (SCC) is a subtype of very aggressive skin cancers that usually develops in sunexposed body regions, but can also affect a large number of organs such as the bladder, esophagus, lungs etc. However, little is known about the biology of these cells, which consequently makes difficult the generation of new specific therapies; actually, the standard treatments are based on surgery and subsequent radiotherapy.

Sox10 gene plays a central role in melanoma

Black skin cancer, also known as melanoma, is particularly aggressive and becoming increasingly common in Switzerland. Despite intensive research, however, there is still no treatment. Researchers from the University of Zurich have now discovered a gene that plays a central role in black skin cancer. Suppressing this gene in mice inhibits the development of melanoma and its proliferation - a discovery that could pave the way for new forms of therapy.

Bioengineers develop microfluidic platform to mechanically confine cancer cells

It's well known in conventional biology that during the process of mammalian cell division, or mitosis, a mother cell divides equally into two daughter cells. But when it comes to cancer, say UCLA researchers, mother cells may be far more prolific.
