Study shows that age and sleep deprivation induce cellular stress in pancreas

Sleep, or the lack of it, seems to affect just about every aspect of human physiology. Yet, the molecular pathways through which sleep deprivation wreaks its detrimental effects on the body remain poorly understood.

New reports demonstrate the effectiveness of modified T cells in treating blood-borne cancers

At the 2013 American Society of Hematology meeting in Dec. 2013, James Kochenderfer, M.D., investigator in the Experimental Transplantation and Immunology Branch, NCI, presented findings from two clinical trials evaluating the use of genetically modified immune system T cells as cancer therapy.

New strategy for fighting infection targets patient's cells rather than invading pathogens

As more reports appear of a grim "post-antibiotic era" ushered in by the rise of drug-resistant bacteria, a new strategy for fighting infection is emerging that targets a patient's cells rather than those of the invading pathogens.

IDIBELL researchers explain the regulator mechanisms of mitosis

Researchers at the Cell Cycle Research Group of the Bellvitge Institute of Biomedical Research (IDIBELL) led by Ethel Queralt have reported in the journal PLoS Genetics an article which delve into the regulator mechanisms of mitosis, a key stage of the cell-cycle for the correct transmision of genetic information from parents to sons.

Late-breaking abstracts on treatment of blood cancers and bleeding disorders presented at ASH meeting

A range of studies highlighting late-breaking research advances in the understanding and treatment of blood cancers and bleeding disorders are being presented today during the 55th American Society of Hematology Annual Meeting and Exposition in New Orleans.

Ribosomal proteins RPL5, RPL11 play essential role in normal cell proliferation

Researchers from the Laboratory of Cancer Metabolism (LCM) led by George Thomas at the Bellvitge Biomedical Research Institute (IDIBELL), the Catalan Institute of Oncology (ICO) and the Division of Hematology/ Oncology, University of Cincinnati, have shown that loss of either one of two tumor suppressors, ribosomal proteins RPL5 or RPL11, fail to induce cell-cycle arrest, but prevent the proliferation of cells as they have a reduced capacity to synthesize proteins.

Lund University researcher explores why type 2 diabetes raises dementia risk later in life

It is well known that type 2 diabetes raises the risk of dementia. The reasons for this are less clear, but one explanation could be insulin resistance in the brain, according to Malin Wennstr-m, a researcher at Lund University's Molecular Memory Research Unit. She has received EUR 700,000 from the Swedish Research Council to investigate her theory.

Researchers refute avalanche theory on cancer

First, the number of chromosomes in a cell changes, then an avalanche of further mutations occur that transform the cell into a cancer cell, according to a well-known - but untested - theory.

Immunocellular Therapeutics reports positive results from ICT-107 Phase II study in glioblastoma patients

ImmunoCellular Therapeutics, Ltd. ("ImmunoCellular") announced that ICT-107, its dendritic cell-based vaccine, demonstrated a statistically significant increase in progression-free survival (PFS) in patients with newly diagnosed glioblastoma multiforme (GBM) in its randomized, placebo-controlled phase II trial.

Queen's University to lead €6 million European study to find new treatments for bowel cancer

Queen's University has announced it is to lead a -6 million European study to find new treatments for bowel cancer.

New mechanism explains why anti-tumor activity of specific immune suppressed during tumor growth

The Leuven-based VIB researchers have revealed a mechanism that explains why the anti-tumor activity of specific immune cells called macrophages is suppressed during tumor growth. They have also demonstrated that blocking the protein Nrp1 can restore this anti-tumor immune response.

Scientists explore mechanisms of viruses' shells

Viruses are like small vessels containing an active component, the genetic material, that can infect a host cell. The vessel, called capsid or vector, is basically a shell that changes its shape when it penetrates a cell to infect it, and may even break into pieces.

Probe mimics pathogen's amino acids, solving mystery behind Chlamydiae cell wall

Biochemical sleuthing by an Indiana University graduate student has ended a nearly 50-year-old search to find a megamolecule in bacterial cell walls commonly used as a target for antibiotics, but whose presence had never been identified in the bacterium responsible for the most commonly reported sexually transmitted disease in the United States.

Elevated BACE1 activity in mild cognitive impairment could be early indicator of AD, says study

The critical enzyme beta-secretase1 (BACE1) is known to be elevated in brains with sporadic Alzheimer disease (AD). Scientists have now found increased levels of BACE1 in brains with mild cognitive impairment (MCI), suggesting that BACE1 activity is important for conversion of mild cognitive impairment to AD and may be an early indicator of AD.

New study may pave way for more effective treatment for deadly childhood cancer

A new study by Canadian researchers may pave the way for more effective treatment of an aggressive and deadly type of brain tumour, known as ETMR/ETANTR. The tumour, which is seen only in children under four, is almost always fatal, despite aggressive treatment. The study proposes a new model for how this brain tumour develops and suggests possible targets to investigate for novel therapies.

Study resolves 50-year 'chlamydial anomaly' using novel method

Researchers studying Chlamydia trachomatis bacteria, which cause the sexually transmitted infection chlamydia as well as infectious blindness, have confirmed that the bacteria contain-and, in fact, cannot function without-the common molecule peptidoglycan, a structural component found in the cell wall of many bacteria. This finding puts an end to years of uncertainty about whether Chlamydia bacteria, like almost all bacterial species, rely on peptidoglycan to reproduce and to maintain their shape and structure. In addition, the novel method the investigators used may be adapted to further examine the molecule's role in the structure and function of other bacteria.

Two tumor-suppressing genes could play vital role in controlling obesity, cancer, diabetes

The function of two tumor-suppressing genes could play a vital role in helping to control obesity and other diseases such as diabetes, heart disease and cancer, according to researchers in Temple University's Sbarro Institute for Cancer Research and Molecular Medicine.
