Researchers discover new way to target bacterial cell wall

The bacterial cell wall must be constantly remodeled in order to grow and divide. This involves the close coordination of lytic enzymes and peptidoglycan synthesis.

Study sheds light on how viruses override host cell's DNA replication machinery

University of Pittsburgh researchers have shown for the first time how Merkel cell polyomavirus (MCV), which causes an aggressive skin cancer called Merkel cell carcinoma, initiates DNA replication in host cells.

Scientists discover new mechanism for kidney cell renewal

University of Texas at Dallas scientists have discovered a previously unknown "housekeeping" process in kidney cells that ejects unwanted content, resulting in cells that rejuvenate themselves and remain functioning and healthy.

Green tea compound may offer new treatment option for uterine fibroids

In a pre-clinical, proof-of-concept study from Johns Hopkins Medicine, researchers found that epigallocatechin gallate (EGCG), a green tea compound with powerful antioxidant properties, could be promising for both treating and preventing uterine fibroids.

Many patients with Lynch syndrome remain undiagnosed, study finds

New research from Cedars-Sinai Cancer investigators could warrant reconsideration of current screening guidelines to include a poorly recognized cause of Lynch syndrome, the most common cause of hereditary colorectal and endometrial cancers.

Study traces the natural evolution of earliest stages of human cancers

Cancer cells-to-be accumulate a series of specific genetic changes in a predictable and sequential way years before they are identifiable as pre-malignancies, researchers at Stanford Medicine have found.

Plant cells push away microtubules to control cell division, study finds

Every time a stem cell divides, one daughter cell remains a stem cell while the other takes off on its own developmental journey.

3D models of ovarian cancer reveal how cell’s location can affect tumor biology

Using 3-D models of ovarian cancer tumors, scientists found differences in gene activity based on where a cell is in a tumor, demonstrating how a cell's location and environment in a cancerous tumor can strongly influence which genes are active and the cell's role in the cancer's biology.

Repurposing cancer drugs for malaria treatment

With malaria becoming increasingly drug-resistant, a team of UCF researchers is looking to use cancer drugs to accelerate the discovery of new life-saving therapies for the disease.

Rensselaer investigator awarded $1.6 million grant to study the mechanics of mitosis to fight cancer

It is a scary fact that one in two women and one in three men in the United States will develop some form of cancer in their lifetime.

Herbal extracts for mental health: Are they safe for pregnant women?

Researchers evaluate the T-cell modulating effects of St. John’s wort, valerian, hops, lavender, and California poppy.

Destroying the tether of shattered chromosomal fragments may help prevent cancerous mutations

Healthy cells work hard to maintain the integrity of our DNA, but occasionally, a chromosome can get separated from the others and break apart during cell division.

Cryo-EM reveals key atomic structures of the ends of actin filament

Actin filaments -; protein structures critical to living movement from single cells to animals -; have long been known to have polarity associated with their physical characteristics, with growing "barbed" and shrinking "pointed" ends.

Parasite-host "coupling" mechanism could lead to new treatments for malaria

Transmitted through infected mosquitos, the malaria parasite, once in the human bloodstream, synchronously ruptures red blood cells and rapidly infects new red blood cells, beginning the cycle anew.

Energy drinks may stunt muscle repair, new study suggests

Energy drinks impede muscle regeneration and reduce physical performance. This study provided evidence of an inhibitory effect on myogenic differentiation and highlighted potential concerns for athletes and fitness enthusiasts.

Fission yeast study sheds new light on gross chromosomal rearrangement

When creating a computer program, errors in the code can introduce bugs to the software. Similarly, errors in our body's genetic code, DNA, which is stored in structures known as chromosomes, can bring about mutations in the body.

Researchers explore the possibility of treating lung cancer by targeting telomeres

Healthy cells can only divide a limited number of times during an organism's lifetime. In contrast, tumor cells are immortal: they proliferate indefinitely and uncontrollably, and this is the defining characteristic of cancer.

Study could help understand why limiting sugary foods can ease symptoms for IBD patients

Excess sugar hampers cells that renew the colon's lining in a mouse model of inflammatory bowel disease (IBD), according to a new study by University of Pittsburgh scientists.
