Study represents starting point for future clinical applications using propolis

A team of researchers from the University of Valencia, the Universitat Politècnica de València, the University Hospital La Fe and the Universitat Autònoma de Barcelona conducted in vitro studies of cytotoxicity (cellular affection) to assess the optimal concentration level of propolis in which this natural substance extracted from bee resin would offer the maximum protection against ionised radiation and not be toxic for blood cells.

Researchers show how aggressive form of multiple myeloma resists chemotherapy

Researchers at Washington University School of Medicine in St. Louis have shown how an aggressive form of multiple myeloma resists chemotherapy.

Researchers probe origin of optimized antibodies against infections

An organism's ability to make new antibodies and use them to optimize its own immune defenses is of central importance in the fight against pathogens. In the case of severe infections, the overall relative speed with which an immune response proceeds could mean the difference between life and death.

WCMC researchers devise innovative boxer-like strategy to fight multiple myeloma

Weill Cornell Medical College researchers have devised an innovative boxer-like strategy, based on the serial use of two anti-cancer drugs, to deliver a one-two punch to first weaken the defenses of multiple myeloma and then deliver the final knock-out punch to win the fight.

KPT-SINEs might offer new treatment for people with acute leukemia

A novel family of experimental agents that blocks a molecule from shuttling proteins out of the cell nucleus might offer a new treatment for people with acute leukemia, according to a study by researchers at the Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute.

New approach to decipher roles of genes associated with autism

Fish cannot display symptoms of autism, schizophrenia or other human brain disorders. However, a team of MIT biologists has shown that zebrafish can be a useful tool for studying the genes that contribute to such disorders.

Genetic variability in the embryo may predispose to cancer in adult life

A study recently published in Nature Genetics provides new evidence that the genetic makeup of the embryo may cause the appearance of tumors in adult life. These results bear out the growing theory that some tumors may have an extremely early origin, tracing to the individual's embryonic development, while offering new clues to understand the genetic causes of certain kinds of cancer, and their prevention and treatment.

Normal p53 gene makes breast cancer chemotherapy with doxorubicin less effective

Presence of normal p53, a tumor suppressor gene, instead of a mutated version, makes breast cancer chemotherapy with doxorubicin less effective. The preclinical study led by MD Anderson scientists was published today in the journal Cancer Cell.

Tp53 genetic mutation may play an important role in prostate cancer

A team of UC Davis investigators has found that a genetic mutation may play an important role in the development of prostate cancer. The mutation of the so-called p53 (or Tp53) gene was previously implicated in late disease progression, but until now has never been shown to act as an initiating factor. The findings may open new avenues for diagnosing and treating the disease.

Scientists discover genetic basis for CLOVES syndrome

Using advanced technologies for rapidly sequencing and analyzing DNA from clinical and pathologic samples, a multidisciplinary research team consisting of geneticists, pathologists and surgeons at Boston Children's Hospital has identified the genetic basis for CLOVES syndrome, a rare congenital malformation and overgrowth disorder.

Beyond chemotherapy to cure leukemia

The fight against cancer is not won in a single battle: long after a cancer has been beaten into remission, it can return. The reason for this is under debate, and much is unclear.

Researchers uncover insights into rare genetic disorders

Researchers studying rare genetic disorders have uncovered insights into those diseases in biological structures that regulate chromosomes when cells divide. Focusing on the cohesin complex, a group of proteins forming a bracelet that encircles chromosome pairs, scientists have discovered mutations that disrupt cohesin, causing a recently recognized class of diseases called cohesinopathies.

Scientists show why leukemia often returns

The fight against cancer is not won in a single battle: Long after a cancer has been beaten into remission, it can return. The reason for this is under debate, and much is unclear. New research led by Weizmann Institute scientists shows that, at least for one type of blood cancer, the source of cancer recurrence is in a set of cells that do not proliferate as quickly as regular cancer cells, and thus able to survive chemotherapy.

UCLA geneticists identify mutation responsible for IMAGe syndrome

UCLA geneticists have identified the mutation responsible for IMAGe syndrome, a rare disorder that stunts infants' growth. The twist? The mutation occurs on the same gene that causes Beckwith-Wiedemann syndrome, which makes cells grow too fast, leading to very large children.

Panobinostat able to target and destroy triple negative breast cancer

The histone de-acetylase (HDAC) inhibitor panobinostat is able to target and destroy triple negative breast cancer, reveals a new study published in BioMed Central's open access journal Breast Cancer Research.

Researchers identify mechanism by which Zds1 protein regulates key function in mitosis

Researchers from the Bellvitge Biomedical Research Institute (IDIBELL) have identified the mechanism by which protein Zds1 regulates a key function in mitosis, the process that occurs immediately before cell division.

Researchers separate low and high-PSA prostate cancer cells

Prostate cancer cells that defy treatment and display heightened tumor-generating capacity can be identified by levels of prostate specific antigen (PSA) expressed in the tumor cells, a research team led by scientists at The University of Texas MD Anderson Cancer Center reports in the May 3 edition of Cell Stem Cell.

PDE4 enzyme regulates division of tumour cells and blood vessel growth in cancer tissue

Lung cancer is the leading cause of cancer death throughout the world. Standard treatment methods do not usually result in long-term recovery. In addition to the proliferation of the tumour cells, the growth of blood vessels controls tumors development. The blood vessel growth is controlled by several signalling molecules. Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim and Justus Liebig University Giessen have discovered a molecule that plays a key role in this process. They succeeded in reducing tumour growth in their experiments by blocking the phosphodiesterase PDE4.

Researchers identify new functions of cohesin SA1 that are relevant for cancer and CdLS

Cohesin is a ring-shaped protein complex involved in the spatial organization of the genome and in mitotic chromosome structure. Vertebrate somatic cells have two versions of cohesin that contain either SA1 or SA2, but their functional specificity has been largely ignored. Researchers of the Spanish National Cancer Research Centre (CNIO) under the direction of Ana Losada have identified new functions of cohesin SA1 that are relevant for two human diseases, cancer and Cornelia de Lange Syndrome.

New genetic pathway influences spread of cancer cells

In a new study from Lawson Health Research Institute, Dr. Joseph Torchia has identified a new genetic pathway influencing the spread of cancer cells. The discovery of this mechanism could lead to new avenues for treatment.
