Selectively down-regulated PD-L1 by albumin-phenformin nanoparticles mediated mitochondrial dysfunction to stimulate tumor-specific immunological response for enhanced mild-temperature photothermal efficacy

open access: yesJournal of Nanobiotechnology, 2021
Highlights Over-expression of PD-L1 after mild-photothermal therapy significantly limited its efficacy. Phenformin could effectively downregulate PD-L1 expression and inhibit tumor metastasis through AMPK activation.

Disruption of BASIGIN decreases lactic acid export and sensitizes non-small cell lung cancer to biguanides independently of the LKB1 status [PDF]

open access: yes, 2014
Most cancers rely on aerobic glycolysis to generate energy and metabolic intermediates. To maintain a high glycolytic rate, cells must efficiently export lactic acid through the proton-coupled monocarboxylate transporters (MCT1/4).

Comparison of Effects of Metformin, Phenformin, and Inhibitors of Mitochondrial Complex I on Mitochondrial Permeability Transition and Ischemic Brain Injury

open access: yesBiomolecules, 2020
Damage to cerebral mitochondria, particularly opening of mitochondrial permeability transition pore (MPTP), is a key mechanism of ischemic brain injury, therefore, modulation of MPTP may be a potential target for a neuroprotective strategy in ischemic ...

Respiratory chain complex I is related to oxidative phosphorylation in gastric cancer stem cells

open access: yesSTEMedicine, 2022
Background: Cancer stem cells (CSCs) are the main cause of resistance to anti-cancer drug therapy and distant metastasis of tumors, including gastric cancer. The metabolism of CSCs is an important factor in the maintenance of its stemness. This study is

Molecular features of biguanides required for targeting of mitochondrial respiratory complex I and activation of AMP-kinase. [PDF]

open access: yes, 2016
BACKGROUND: The biguanides are a family of drugs with diverse clinical applications. Metformin, a widely used anti-hyperglycemic biguanide, suppresses mitochondrial respiration by inhibiting respiratory complex I. Phenformin, a related anti-hyperglycemic

Phenformin attenuates the oxidative-nitrosative stress in the liver of rats under long-term ethanol administration [PDF]

open access: yesThe Ukrainian Biochemical Journal
Modulation of the AMP-activated protein kinase (AMPK) pathway activity is considered to be a promi­sing option in the development of approaches to chronic alcoholic hepatitis treatment. Phenformin, which is a biguanide, has been reported to increase AMPK

Defective Signalling of the BRCA1 Neighbouring gene, NBR2, leads to ER-? Negative tumours in breast cancer xenograft mouse models [PDF]

open access: yesJournal of Veterinary and Animal Sciences, 2022
Majority of breast and ovarian cancer treatment modalities are based on endocrine therapies like antiestrogens which are dependent on the hormone receptor status of tumours.

Metabolic Profiles Associated With Metformin Efficacy in Cancer

open access: yesFrontiers in Endocrinology, 2018
Metformin is one of the most commonly prescribed medications for the treatment of type 2 diabetes. Numerous reports have suggested potential anti-cancerous and cancer preventive properties of metformin, although these findings vary depending on the ...

Metformin: a modulator of bevacizumab activity in cancer? A case report. [PDF]

open access: yes, 2015
Recurrent type I endometrial cancer ((EC)) has poor prognosis and demands novel therapeutic approaches. Bevacizumab, a VEGF-A neutralizing monoclonal antibody, has shown clinical activity in this setting. To our knowledge, however, although some diabetic

Metabolic determinants of cancer cell sensitivity to glucose limitation and biguanides [PDF]

open access: yes, 2013
As the concentrations of highly consumed nutrients, particularly glucose, are generally lower in tumours than in normal tissues1,2, cancer cells must adapt their metabolism to the tumour microenvironment. A better understanding of these adaptations might
