Glycolysis News and Research

RSS

Glycolysis is a series of reactions that helpextract energy from glucose. This is an ancient pathway of metabolism that is present in the majority of living organisms today. It is the foundation of both aerobic and anaerobic cellular respiration. It takes place in the cytosol of a cell and is the foundation of both aerobic and anaerobic cellular respiration.

Rochester scientists propose new reason why acute myeloid leukemia is so difficult to cure

University of Rochester Medical Center scientists have proposed a new reason why acute myeloid leukemia, one of the most aggressive cancers, is so difficult to cure: a subset of cells that drive the disease appear to have a much slower metabolism than most other tumors cells.

p53 activation suppresses malic enzyme expression and leads to senescence in pre-cancerous cells

It is perhaps impossible to overstate the importance of the tumor suppressor gene p53. It is the single most frequently mutated gene in human tumors. p53 keeps pre-cancerous cells in check by causing cells, among other things, to become senescent - aging at the cellular level. Loss of p53 causes cells to ignore the cellular signals that would normally make mutant or damaged cells die or stop growing.

SIRT6 protein may play a critical role in blocking cancer and controlling cellular metabolism

A new study sheds more light on how an anti-aging gene suppresses cancer growth, joint University of Michigan Health System and Harvard Medical School research shows.

Specific transporters could be exploited to deliver toxic substances into cancer cells

Whitehead Institute scientists report that certain molecules present in high concentrations on the surfaces of many cancer cells could be exploited to funnel lethal toxic molecules into the malignant cells. In such an approach, the overexpression of specific transporters could be exploited to deliver toxic substances into cancer cells.

Paper illuminates importance of PKM2 in cancer development and progression

Researchers at The University of Texas MD Anderson Cancer Center have tracked down a cancer-promoting protein's pathway into the cell nucleus and discovered how, once there, it fires up a glucose metabolism pathway on which brain tumors thrive.

Washington University, SRI investigators launch Global Metabolomic Initiative

Investigators at Washington University and The Scripps Research Institute have announced the launch of a "Global Metabolomic Initiative" to facilitate meta-analyses on studies of the metabolism of bacteria, yeast, plants, animals and people.

GlcNAc plays a key role in keeping cancerous monsters ‘fed’

Behaving something like ravenous monsters, tumors need plentiful supplies of cellular building blocks such as amino acids and nucleotides in order to keep growing at a rapid pace and survive under harsh conditions. How such tumors meet these burgeoning demands has not been fully understood.

Study demonstrates how Elesclomol blocks oxidative phosphorylation in melanoma

A laboratory study led by UNC medical oncologist Stergios Moschos, MD, demonstrates how a new targeted drug, Elesclomol, blocks oxidative phosphorylation, which appears to play essential role in melanoma that has not been well-understood. Elesclomol (Synta Pharmaceuticals, Lexington, MA) was previously shown to have clinical benefit only in patients with normal serum lactate dehydrogenase (LDH), a laboratory test routinely used to assess activity of disease.

Pyruvate kinase M2 fuels tumor growth by influencing H3 histone protein

A metabolic protein that nourishes cancer cells also activates tumor-promoting genes by loosening part of the packaging that entwines DNA to make up chromosomes, a team led by scientists at The University of Texas MD Anderson Cancer Center reports in the Aug. 16 issue of Cell.

Passenger deletions that deactivate essential genes provide new opportunity to strike cancer

Genomic deletions promote cancer by carving up or eliminating tumor-suppressor genes, but now scientists report in the journal Nature that the collateral damage they inflict on neighboring genes exposes cancer cells to vulnerabilities and new avenues for attack.

Gluconeogenesis severely compromised in HCC by IL6-Stat3-mediated activation of miR-23a

As liver cancer develops, tumor cells lose the ability to produce and release glucose into the bloodstream, a key function of healthy liver cells for maintaining needed blood-sugar levels.

Study reveals connection among sugar, cancer, and dependence on breathing machines

A new research report published online in the FASEB Journal reveals a connection among sugar, cancer, and dependence on breathing machines--microRNA-320a.

Study investigates how glucose metabolism affects biochemical signals in cancer cells

Compared to normal cells, cancer cells have a prodigious appetite for glucose, the result of a shift in cell metabolism known as aerobic glycolysis or the "Warburg effect." Researchers focusing on this effect as a possible target for cancer therapies have examined how biochemical signals present in cancer cells regulate the altered metabolic state.

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.

Study reveals molecular link between aging and cancer

It has long been known that cancer is a disease of aging, but a molecular link between the two has remained elusive.

Blocking Skp2 protein might inhibit glycolysis and treat breast cancer

HER2 and its epidermal growth factor receptor cousins mobilize a specialized protein to activate a major player in cancer development and sugar metabolism, scientists report in the May 25 issue of Cell.

Glial cells pass on metabolites to neurons

Around 100 billion neurons in the human brain enable us to think, feel and act. They transmit electrical impulses to remote parts of the brain and body via long nerve fibres known as axons. This communication requires enormous amounts of energy, which the neurons are thought to generate from sugar. Axons are closely associated with glial cells which, on the one hand, surround them with an electrically insulating myelin sheath and, on the other hand support their long-term function.

Hypoxia may be a primary cause of uncontrollable tumor growth in cancers

Low oxygen levels in cells may be a primary cause of uncontrollable tumor growth in some cancers, according to a new University of Georgia study. The authors' findings run counter to widely accepted beliefs that genetic mutations are responsible for cancer growth.

Scripps scientists to develop new generation of broad spectrum anti-cancer therapeutics

A pair of Scripps Research Institute scientists, one a cancer biologist and the other a chemist, has been awarded $3.85 million from the National Institutes of Health (NIH) to develop a new generation of broad spectrum anti-cancer therapeutics, including breast cancer and lymphoma.
