To coordinate their size and growth with current environmental conditions, cells rely on the mechanistic target of rapamycin complex 1 (mTORC1) pathway, which senses cellular stresses, growth factors, and the availability of nutrients, such as amino acids and glucose.

In the past 27 years, we have found that this cycling sugar modification of proteins — called O - linked N - acetylglucosamine, or O - GlcNAc — is nearly as common as protein phosphorylation and often competes with it at the same or proximal sites on proteins to regulate nearly every cellular process in response to nutrients and stress.

«In a stressed intestinal environment,» the authors note, «retinoic acid, which was thought to lessen inflammation in the intestine, acted as an adjuvant that promoted rather than prevented inflammatory cellular and humoral responses to fed antigen.»

Numerous studies have demonstrated activity of these agents against a wide variety of cancers, especially cancer stem cell - like subpopulations, by a host of different mechanisms which comprise inhibition of signaling pathways, of mitochondrial respiration, as well as of cellular stress responses and others.

My lab at HPU studies membrane traffic during times of cellular stress using baker's yeast as a model system.

The Keap1 - Nrf2 system has evolved to respond to intracellular oxidative stress; in particular the generation of reactive electrophiles produced from oxidation of endogenous cellular constituents as well as xenobiotics [2]--[4].

Scientists have known that, in organisms ranging in complexity from yeast to humans, different kinds of cellular stress — such as a backlog of unfolded proteins, DNA - damaging UV light, a shortage of the amino acid building blocks needed to make protein, viral infection, iron deficiency — trigger different enzymes to act downstream to switch off eIF2 alpha.

Using these orthogonal measures of cellular pathway analysis, we confirmed that HPP - 4382, in contrast to bardoxolone, did not induce significant cellular stress at high doses as measured by HSPA6 expression and that the mechanism of HPP - 4382 activity does not appear dependent on NF - B as ICAM1 expression is not induced by HPP - 4382 (data not shown).

In response to cellular stress such as DNA damage, oncogene activation, transcriptional inhibition, and hypoxia, tumor suppressor p53 is activated and expressed, and acts as a transcription factor to induce its target genes [1], thereby playing a central role in the regulation of DNA repair, cell cycle, apoptosis, senescence, and angiogenesis [2 - 4].

Observed toxicity was strongly correlated with intracellular oxidative stress, measured as protein carbonylation, but not to cellular uptake.

â $ œIt is well known that the immune system can detect and respond to pathogens, but these results highlight its capacity to sense and adapt to environmental changes, such as nutritional starvation, which cause cellular stress, â $ he says.

Enhanced amyloidogenic processing of APP by the ß - site APP cleaving enzyme (BACE) and the γ - secretase complex and reduced clearance lead to increased intracellular levels of soluble oligomeric Aß, resulting in cellular dysfunction comprising e.g., synaptic failure, mitochondrial dysfunction, enhanced oxidative stress, neurotransmitter and neurotrophin depletion, inflammation, and apoptosis which is reflected in patients as clinical symptoms such as cognitive deficits [2, 3].

A study carried out by Spanish researchers found that training to failure stresses muscles to the point that they're depleted of energy, as measured by an increase in AMP, a cellular energy signal that cells are depleted of energy.

That stress can break down the muscles at the cellular level, and as neighboring cells repair them, the muscle cells can become enlarged.

IV Vitamin Therapy has been used as effective therapy in preventative and anti-aging medicine in improving physical and mental performance, DNA replication, immune support, and reducing inflammation or oxidative stress at a cellular level.

This sets off a chain reaction of imbalance and damage at the cellular level referred to as oxidative stress - a condition thought to be a core factor in the aging process itself!

Similar to the physical and cellular burn of exercise that creates some oxidizing free radicals, the «stress» from cruciferous vegetables stimulates our mitochondria to produce homemade antioxidants to counterbalance the oxidation and protect our vital DNA.28 Even cancer cells have caught on to this central role of our mitochondria — the bastards can amplify their levels of some of these same pathways — further stressing their importance for survival.25 However, our cells still seem to have the upper hand, as multiple studies show that the organosulfur chemicals in many of these anticancer vegetables can severely stress cancer cells, leading to oxidative damage, and ultimately, death.29

Studies even suggest that sprouts from cruciferous vegetables provide greater chemoprevention than mature vegetables.30 While vegetables and their defensive chemicals may stimulate our cancer - fighting machinery through cellular stress, their ability to disarm carcinogens before they strike may be just as important.

NF - kB translates stress by activating genes to produce proteins called cytokines that cause inflammation at cellular level — a reaction that is useful as a short - lived fight - or - flight reaction, but if persistent leads to a higher risk of cancer, accelerated aging and psychiatric disorders like depression.

When mice are genetically modified to lose Nrf2 function, they also lose many of the anti-inflammatory and antioxidant benefits of isocyothianate exposure, further linking cruciferous vegetables and Nrf2.41 Studies even suggest that Nrf2 is required to gain the beneficial effects of isocyothianates, connecting the benefits of exercise, fasting, periodic ketogenesis, and healthy cellular stresses with vegetable and spice consumption, as they all can stress our cells and engage Nrf2.42
