Gene Expression News and Research

RSS

Gene Expression is the process by which a gene gets turned on in a cell to make RNA and proteins. Gene expression may be measured by looking at the RNA, or the protein made from the RNA, or what the protein does in a cell.

EPFL scientists show how a major effector protein binds chromatin and regulates gene expression

Inside the cell, DNA is tightly coiled and packed with several proteins into a structure called "chromatin", which allows DNA to fit in the cell while also preventing genes from being expressed at the wrong time. Guided by a chemical "barcode", specialized effector proteins can bind chromatin and either unwind it or compact further to activate or silence genes.

Rare form of autoimmune syndrome may be tied to mutations in AIRE gene

A hereditary autoimmune disease that was thought to be exceedingly rare may have a less severe form that affects one in 1,000 people or even more, according to new research conducted at the Weizmann Institute of Science, in Israel, and the University of Bergen, in Norway.

Identifying obstructive coronary artery disease in women: an interview with Dr. Ladapo, NYU School of Medicine

A recent study presented at the American College of Cardiology 64th Annual Scientific Meeting evaluated the impact of an age, sex, and gene expression score on clinical decision-making and the rate of further cardiac evaluation in symptomatic female patients suggestive of CAD in the outpatient setting.

Researchers create cell lines to study gene expression in precursor brown fat and white fat cells

Since the 2009 discovery that energy-burning brown fat can be active in adults, research has raced ahead to understand this tissue and exploit it to treat the epidemic of obesity. Active brown fat also may assist in directly easing the burden of diabetes and related metabolic diseases by lowering the levels of glucose and fatty acids in the bloodstream. But progress in studying human brown fat often has been slowed by difficulties in obtaining and studying samples of the human cells that develop into brown fat.

OncoSec enrolls first patient in Phase II trial of ImmunoPulse IL-12 for treatment of HNSCC

OncoSec Medical Inc., a company developing DNA-based intratumoral cancer immunotherapies, announced today that the company has enrolled the first patient into OMS-I130, a Phase II clinical trial of ImmunoPulse IL-12 in patients with treatment-refractory, metastatic and unresectable squamous cell carcinoma of the head and neck (HNSCC).

Novartis presents positive Phase III results of Farydak therapy at EHA

Novartis today presented results from a pivotal Phase III clinical trial exploratory subgroup analysis showing a 7.8-month improvement in median progression-free survival when using Farydak in combination with bortezomib and dexamethasone in patients with relapsed or relapsed and refractory multiple myeloma who had received two or more prior regimens, including bortezomib and an immunomodulatory agent.

Scientists report that mouse with weak bones appears to have strong metabolism

One mouse with weak bones appears to have a strong metabolism, even on a high-fat diet, scientists report. While weaker bones are clearly not a good thing, scientists suspect that, somewhere in the conversation between the genetically engineered mouse's skeleton and the rest of its body, there may be an answer that helps obese individuals avoid some of the worst ravages of this health epidemic.

Scientists develop new technique to analyze bacterial populations

Scientists from the Icahn School of Medicine at Mount Sinai have developed a new technique to more precisely analyze bacterial populations, to reveal epigenetic mechanisms that can drive virulence. The new methods hold the promise of a potent new tool to offset the growing challenge of antibiotic resistance by bacterial pathogens.

Study explores role of ALK1 protein in breast cancer metastasis

Pietras said that although prognosis for breast cancer is relatively good when detected in its early stages, metastatic disease is the cause of 90 percent of all cancer-related deaths. Therefore, learning more about the metastatic process and finding new cures to inhibit disease spread is at the center of clinical attention.

Combination of tosedostat and LDAC results in overall response rate of 54% in elderly patients with AML

CTI BioPharma Corp. today announced findings from an investigator-sponsored Phase 2 trial in patients with either primary (de novo) acute myeloid leukemia (AML) or AML that has evolved from myelodysplastic syndrome (MDS). Results showed the combination of tosedostat with low dose cytarabine/Ara-C (LDAC) resulted in an overall response rate (ORR) of 54 percent in elderly patients with AML – with 45 percent of patients achieving durable complete responses (CR).

Researchers discover new aspect of gene regulation

Researchers at the Max F. Perutz Laboratories of the University of Vienna and the Medical University of Vienna as well as at the University of Natural Resources and Life Sciences in Vienna have discovered an entirely new aspect of gene regulation they call exitron splicing.

New insights on crop-rotation resistant rootworms may help develop sustainable agricultural practices

After decades of effort, scientists are finally figuring out how insects develop resistance to environmentally friendly farming practices - such as crop rotation - that are designed to kill them. The researchers say their insights will help develop more sustainable agricultural practices.

New study links sleep deprivation to etiology of biological aging in older adults

A new study suggests that one night of partial sleep deprivation promotes biological aging in older adults. Results show that one night of partial sleep deprivation activates gene expression patterns in peripheral blood mononuclear cells (PBMCs) consistent with increasing accumulation of damage that initiates cell cycle arrest and increases susceptibility to senescence.

New study shows that estrogen receptors vanish in cervical cancer tumors

Scientists have prior evidence that the hormone estrogen is a major driver in the growth of cervical cancer, but a new study examining genetic profiles of 128 clinical cases reached a surprising conclusion: Estrogen receptors all but vanish in cervical cancer tumors.

Researchers generate computer models for targeted drug therapy on DIPG cancer cells

The results of a recent study on targeted therapy of a specific type of brain cancer were published by Nature Medicine showing specific progress in cancer treatment.

Gold nanoparticles with functional surfaces regulate osteogenic differentiation of stem cells

Tissue Regeneration Materials Unit (Guoping Chen, Unit Director) at the International Center for Materials Nanoarchitectonics (MANA) (Masakazu Aono, Director General, MANA), NIMS (Sukekatsu Ushioda, President) successfully developed gold nanoparticles that have functional surfaces and act on osteogenic differentiation of stem cells.

Regulus Therapeutics begins RG-012 Phase I clinical study for treatment of Alport syndrome

Regulus Therapeutics Inc., a biopharmaceutical company leading the discovery and development of innovative medicines targeting microRNAs, announced today that dosing has begun in a first-in-human Phase I clinical study of RG-012, a single stranded, chemically modified oligonucleotide that binds to and inhibits the function of microRNA-21 ("miR-21").

University of Chicago scientists develop new technique to accurately measure epigenetic changes

One of the most widely used tools in epigenetics research - the study of how DNA packaging affects gene expression - is chromatin immunoprecipitation (ChIP), a technique that allows researchers to examine interactions between specific proteins and genomic regions. However, ChIP is a relative measurement, and has significant limitations that can lead to errors, poor reproducibility and an inability to be compared between experiments.

Novel strategy shows aptamer-based modular delivery of microRNA in endothelial, breast cancer cells

Researchers have shown that a novel delivery strategy can efficiently introduce a functional microRNA that has anti-cancer and angiogenic activities into two different types of cells--breast cancer cells to inhibit tumor growth and metastasis, and cells that line blood vessels to protect against atherosclerosis.
