Fabrication and Characterization of Ultrathin-ring Electrodes for Pseudo-steady-state Amperometric Detection.

Analytical sciences : the international journal of the Japan Society for Analytical Chemistry

Kitazumi Y, Hamamoto K, Noda T, Shirai O, Kano K.
PMID: 26165281
Anal Sci. 2015;31(7):603-7. doi: 10.2116/analsci.31.603.

The fabrication of ultrathin-ring electrodes with a diameter of 2 mm and a thickness of 100 nm is established. The ultrathin-ring electrodes provide a large density of pseudo-steady-state currents, and realize pseudo-steady-state amperometry under quiescent conditions without a Faraday...

Assessment of Brown Adipocyte Thermogenic Function by High-throughput Respirometry.

Bio-protocol

Mahdaviani K, Benador I, Shirihai O.
PMID: 29770346
Bio Protoc. 2015 Nov 05;5(21). doi: 10.21769/BioProtoc.1641.

Brown adipose tissue (BAT) has the unique ability to dramatically increase mitochondrial uncoupled fuel oxidation for thermogenesis in response to adrenergic stimulation. A key parameter in assessing brown adipocyte thermogenic capacity is mitochondrial uncoupling as determined by respiration. Measuring...

A precision therapeutic strategy for hexokinase 1-null, hexokinase 2-positive cancers.

Cancer & metabolism

Xu S, Catapang A, Braas D, Stiles L, Doh HM, Lee JT, Graeber TG, Damoiseaux R, Shirihai O, Herschman HR.
PMID: 29988332
Cancer Metab. 2018 Jun 28;6:7. doi: 10.1186/s40170-018-0181-8. eCollection 2018.

BACKGROUND: Precision medicine therapies require identification of unique molecular cancer characteristics. Hexokinase (HK) activity has been proposed as a therapeutic target; however, different hexokinase isoforms have not been well characterized as alternative targets. While HK2 is highly expressed in...

Deletion of ABCB10 in beta-cells protects from high-fat diet induced insulin resistance.

Molecular metabolism

Shum M, Segawa M, Gharakhanian R, Viñuela A, Wortham M, Baghdasarian S, Wolf DM, Sereda SB, Nocito L, Stiles L, Zhou Z, Gutierrez V, Sander M, Shirihai OS, Liesa M.

Mol Metab. 2021 Nov 22;101403. doi: 10.1016/j.molmet.2021.101403. Epub 2021 Nov 22.

AIMS: The contribution of beta-cell dysfunction to type 2 diabetes (T2D) is not restricted to insulinopenia in the late stages of the disease. Elevated fasting insulinemia in normoglycemic humans is a major factor predicting the onset of insulin resistance...

ATP-consuming futile cycles as energy dissipating mechanisms to counteract obesity.

Reviews in endocrine & metabolic disorders

Brownstein AJ, Veliova M, Acin-Perez R, Liesa M, Shirihai OS.
PMID: 34741717
Rev Endocr Metab Disord. 2021 Nov 06; doi: 10.1007/s11154-021-09690-w. Epub 2021 Nov 06.

Obesity results from an imbalance in energy homeostasis, whereby excessive energy intake exceeds caloric expenditure. Energy can be dissipated out of an organism by producing heat (thermogenesis), explaining the long-standing interest in exploiting thermogenic processes to counteract obesity. Mitochondrial...

Mitochondrial oxidative function in NAFLD: Friend or foe?.

Molecular metabolism

Shum M, Ngo J, Shirihai OS, Liesa M.
PMID: 33276146
Mol Metab. 2021 Aug;50:101134. doi: 10.1016/j.molmet.2020.101134. Epub 2020 Dec 01.

BACKGROUND: Mitochondrial oxidative function plays a key role in the development of non-alcoholic fatty liver disease (NAFLD) and insulin resistance (IR). Recent studies reported that fatty liver might not be a result of decreased mitochondrial fat oxidation caused by...
