Type:
Glycogen
• Many tumors, especially under hypoxic or nutrient-deprived conditions, reprogram their metabolism to store glycogen as an energy reserve.

• Increased glycogen accumulation can serve as a survival mechanism that helps cancer cells endure metabolic stress, which, in turn, may be associated with more aggressive behavior.

• Prognosis:
– In certain cancers (e.g., certain glioblastomas, pancreatic cancers), high intratumoral glycogen content has been associated with adaptation to hypoxia and resistance to therapy.
– Such adaptations often correlate with a poorer prognosis, as the glycogen reservoir helps support tumor progression under adverse conditions.
Frequently increased (accumulated) in tumors exposed to hypoxia, nutrient deprivation, or intermittent perfusion.

Glycogen accumulation in cancer marks a stress-adapted metabolic state. It functions as an internal energy and redox buffer that enables tumors to survive hypoxia and treatment-induced shocks.

1854- dietFMD,    How Far Are We from Prescribing Fasting as Anticancer Medicine?
- Review, Var, NA
ChemoSideEff↓, ample nonclinical evidence indicating that fasting can mitigate the toxicity of chemotherapy and/or increase the efficacy of chemotherapy.
ChemoSen↑, Fasting-Induced Increase of the Efficacy of Chemotherapy
IGF-1↓,
IGFBP1↑, biological activity of IGF-1 is further compromised due to increased levels of insulin-like growth factor binding protein 1 (IGFBP1)
adiP↑, increased levels of adiponectin stimulate the fatty acid breakdown.
glyC↓, After depletion of stored glycogen, which occurs usually 24 h after initiation of fasting, the fatty acids serve as the main fuels for most tissues
E-cadherin↑, upregulation of E-cadherin expression via activation of c-Src kinase
MMPs↓, decrease of cytokines, chemokines, metalloproteinases, growth factors
Casp3↑, increase of level of activated caspase-3
ROS↑, it is postulated that the beneficial effects of fasting are ascribed to rapid metabolic and immunological response, triggered by a temporary increase in oxidative free radical production
ATP↓, Glucose deprivation leads to ATP depletion, resulting in ROS accumulation
AMPK↑, Additionally, ROS activate AMPK
mTOR↓, Under conditions of glucose deprivation, AMPK inhibits mTORC1
ROS↑, Beyond glucose deprivation, another mechanism increasing ROS levels is the AA (amino acids) starvation
Glycolysis↓, Indeed, in cancer cells, limited glucose sources impair glycolysis, decrease glycolysis-based NADPH production due to reduced utilization of the pentose phosphate pathway [88,89,90,91],
NADPH↓,
OXPHOS↝, and shift the metabolism from glycolysis to oxidative phosphorylation (OXPHOS) (“anti-Warburg effect”), leading to ROS overload [92,93,94,95].
eff↑, Fasting compared to long-term CR causes a more profound decrease in insulin (90% versus 40%, respectively) and blood glucose (50% versus 25%, respectively).
eff↑, FMD have been demonstrated to result in alterations of the serum levels of IGF-I, IGFBP1, glucose, and ketone bodies reminiscent of those observed in fasting
*RAS↓, A plausible explanation of the differential protective effect of fasting against chemotherapy is the attenuation of the Ras/MAPK and PI3K/Akt pathways downstream of decreased IGF-1 in normal cells
*MAPK↓,
*PI3K↓,
*Akt↓,
eff↑, Starvation combined with cisplatin has been shown in vitro to protect normal cells, promoting complete arrest of cellular proliferation mediated by p53/p21 activation in AMPK-dependent and ATM-independent manner
ROS↑, generation of ROS due to paradoxical activation of the AKT/S6K, partially via the AMPK-mTORC1 energy-sensing pathways malignant cells
Akt↑, cancer cells
Casp3↑, combination of fasting and chemotherapy was in part ascribed to enhanced apoptosis due to activation of caspase 3

5795- MET,    Metformin: A Review of Potential Mechanism and Therapeutic Utility Beyond Diabetes
- Review, AD, NA - Review, Park, NA - Review, Diabetic, NA
*AntiDiabetic↑, Metformin has been designated as one of the most crucial first-line therapeutic agents in the management of type 2 diabetes mellitus.
*AMPK↑, acts majorly by activating AMPK (Adenosine Monophosphate-Activated Protein Kinase) in the cells and reducing glucose output from the liver.
*glyC↓, It also decreases advanced glycation end products and reactive oxygen species production in the endothelium apart from regulating the glucose and lipid metabolism
*ROS↓,
*cardioP↑, hence minimizing the cardiovascular risks.
*neuroP↑, Preclinical studies have also shown some evidence of metformin’s neuroprotective role in Parkinson’s disease, Alzheimer’s disease, multiple sclerosis and Huntington’s disease.
*Half-Life↝, The plasma half-life of metformin is 2–3 hours, and the active duration is about 6–10hrs.
*toxicity↝, Metformin use for an extended period is linked to a deficiency of vitamin B12.
*BioAv↑, Absolute bioavailability 50–60% in healthy individuals
*glucose↓, Conventionally, it is quite established that metformin lowers blood glucose primarily by its action on the liver
*AGEs↓, Metformin decreases the synthesis of AGE (“Advanced Glycation End”) product formation and hyperglycaemic-induced ROS (“Reactive Oxygen Species”) production
AntiCan↑, There is growing evidence that metformin has anti-cancer effects based on clinical and preclinical studies.
Risk↓, reported that metformin use might decrease the risk of lung cancer within T2D patients as compared to other conventional agents.
TumCP↓, Several studies on cancer cell lines have observed that metformin treatment leads to inhibition of development and proliferation and induces apoptosis of the cancer cells
Apoptosis↑,
TumCCA↑, Metformin was found to block the cell cycle in the “G(0)/G(1)” phase
cycD1/CCND1↓, and this was observed with a sharp drop in the cyclin D1 levels, pRb phosphorylation, and elevated p27(kip) expression.
pRB↓,
p27↓,
mTOR↓, as well as inhibits the mTOR pathway that is activated by insulin.
Casp↑, Metformin is also responsible for inducing caspase-dependent apoptosis along with c- JNK (“Jun N-Terminal Kinase”) activation, oxidative stress and mitochondrial depolarization.
ROS↑,
MMP↓,
ChemoSen↑, patients who received metformin along with the chemotherapy had better pathologic responses as compared to the group without metformin
*hepatoP↑, effects including cardioprotective, hepatoprotective, anti-malignant, and geroprotective effects
*CRM↑, mechanism behind the process of calorie restriction is a reduction in insulin
*Insulin↓,
