Cancer Inhibition by Inositol Hexaphosphate (IP6) and Inositol: From Laboratory to Clinic
One patient with liver metastasis refused chemotherapy after the first treatment, and she was treated only with IP6 plus inositol; her control ultrasound and abdominal computed tomography scan 14 mo after surgery showed a significantly reduced growth rate. A single treatment of HepG2 cells in vitro by IP6 resulted in the complete loss of the ability of these cells to form tumors when inoculated subcutaneously in nude mice (48)

Utilize biochemistry to help you lose weight and stay healthy! Blood clots can also affect the large venous draining systems of the brain in a condition known as cerebral sinus thrombosis. Learn what controls cardiac output, or how much blood the heart pumps per minute, and why it can be devastating when cardiac output falls below acceptable limits
While initial studies focused on the damaging effects of reactive oxygen species, a recent paradigm shift has shown that mROS can act as signaling molecules to activate pro-growth responses. totext() Owen MR, Doran E, Halestrap AP: Evidence that metformin exerts its anti-diabetic effects through inhibition of complex 1 of the mitochondrial respiratory chain
With minor exceptions, the genetic code used by all living organisms is the same.The chemical reactions that take place in living cells are similar as well. The process of photosynthesis requires energy, in the form of sunlight, to split one water molecule into one-half of an oxygen molecule (O2; the oxidizing agent) and two hydrogen atoms (H; the reducing agent), each of which dissociates to one hydrogen ion (H+) and one electron
To identify consensus of differentially regulated miRNA between CCPRCC, CCRCC, and PRCC, we additionally determined differential miRNA expression using 2 publically available microarray data sets from the NCBI Gene Expression Omnibus database (GSE41282 and GSE3798). Whether the strong expression of MET indicates a potential therapeutic target is still unknown and requires further investigation in clinical trials.Related: Chromosome 17 Chromosome 7 Chromosome Y FISH Kidney Cancer MET gene Wach S, Nolte E, Theil A, et al.MicroRNA profiles classify papillary renal cell carcinoma subtypes.Br J Cancer
Cell Death and Disease - Cancer metabolism: current perspectives and future directions
Epidemiological studies have highlighted that the population having low sugar, low fat culinary traditions present lower incidence of cancer.98 Furthermore, studies in mice have showed that feeding the animal a low carbohydrate, high protein diet, not only decreased cancer development but also reduced tumor growth.99 Links between diabetes and cancer have also been established. This causes mTOR-mediated energetic stress and cell death.44 This indicates that loss of TSC, like loss of p53, promotes synthetic lethality with blockade of glycolysis.We have discussed above examples of signaling pathways that promote synthetic lethality with metabolic inhibitors
adaptive peak An equilibrium state in a population when the gene pool has allele frequencies that maximize the average fitness of a population's members. adenosine diphosphate (ADP) A nucleotide consisting of adenine, ribose, and two phosphate groups; formed by the removal of one phosphate from an ATP molecule
Links between metabolism and cancer
(B) This cartoon illustrates the significantly different number of cell divisions needed to produce an adult elephant versus a mouse from similar-sized embryos. When a high-fat diet is only available during the light or sleep cycle, mice gain more weight than those with the same diet available during the dark, active wake cycle
Xenobiotic metabolism a series of enzymatic reactions that convert a foreign chemical compound into an inert substance that can be safely excreted from the body. HDL-cholesterol is considered "good cholesterol," because higher blood levels of HDL-cholesterol are associated with lower risk of cardiovascular disease

How does the metabolism of tumour cells differ from that of normal cells
For example, the unique mechanisms that are involved in the regulation of enhanced glycolysis and glutaminolysis and how do glycolysis, glutaminolysis and mitochondrial respiration liaise. Besides regulation by transcription factors, modulation can be achieved by compounds formed along the sequential reactions of interconnecting pathways that accumulate and bind directly to the allosteric sites of the cognate enzymes
I really appreciate this explanation, many thanks Reply jake says: May 8, 2011 at 23:30 Great review before my AP bio test, many thanks! Reply Ikpoku Justice says: March 25, 2011 at 08:37 i appreciate your site and how its making science easy. Reply Rob says: November 20, 2010 at 18:30 dear admin, i dont know if this comment site is also designed for questions, but as a lay person trying to understand a metabolic condition my 10 yr old son has, i found your description of the krebs cycle easy to follow
Expression - Biology-Online Dictionary
expressed genes include those that are transcribed into mrna and then translated into protein and those that are transcribed into rna but not translated into protein (for example, transfer and ribosomal RNAs)
If antioxidant and conjugation steps are impaired, then a large number of free radicals will be produced which can cause oxidative damage within the liver and also spill out into the blood stream, flooding it with excessive free radicals. In addition, poor immune function may result in cytokines attaching themselves to the mitochondrial membrane, and perhaps causing mitochondrial clumping (which in turn may disturb the function of the cytoskeleton within the cytoplasm of the cells)
