Leukemic stem cells (LSCs) can acquire non-mutational resistance following drug treatment leading to therapeutic failure and relapse. However, oncogene-independent mechanisms of drug persistence in LSCs are incompletely understood, which is the primary focus of this study. We integrated proteomics,...

Calorie restriction (CR) promotes healthy ageing in diverse species. Recently, it has been shown that fasting for a portion of each day has metabolic benefits and promotes lifespan. These findings complicate the interpretation of rodent CR studies, in which...

Mitochondrially targeted compounds and their impact on cellular bioenergetics.

Mitochondria are recognized as critical sites of localized injury in a number of chronic pathologies which has led to the development of organelle directed therapeutics. One of the approaches employed to target molecules to the mitochondrion is to conjugate...

The mortality rates among patients who initially survive sepsis are, in part, associated with a high risk of secondary lung infections and respiratory failure. Given that phagolysosomes are important for intracellular killing of pathogenic microbes, we investigated how severe...

Hedgehog Signaling Regulates Metabolism and Polarization of Mammary Tumor-Associated Macrophages.

Cancer research

Hinshaw DC, Hanna A, Lama-Sherpa T, Metge B, Kammerud SC, Benavides GA, Kumar A, Alsheikh HA, Mota M, Chen D, Ballinger SW, Rathmell JC, Ponnazhagan S, Darley-Usmar V, Samant RS, Shevde LA.

Elevated infiltration of immunosuppressive alternatively polarized (M2) macrophages is associated with poor prognosis in patients with cancer. The tumor microenvironment remarkably orchestrates molecular mechanisms that program these macrophages. Here we identify a novel role for oncogenic Hedgehog (Hh) signaling...

A role for GLUT3 in glioblastoma cell invasion that is not recapitulated by GLUT1.

Cell adhesion & migration

Libby CJ, Gc S, Benavides GA, Fisher JL, Williford SE, Zhang S, Tran AN, Gordon ER, Jones AB, Tuy K, Flavahan W, Gordillo J, Long A, Cooper SJ, Lasseigne BN, Augelli-Szafran CE, Darley-Usmar V, Hjelmeland AB.

The multifaceted roles of metabolism in invasion have been investigated across many cancers. The brain tumor glioblastoma (GBM) is a highly invasive and metabolically plastic tumor with an inevitable recurrence. The neuronal glucose transporter 3 (GLUT3) was previously reported...

The Role of Autophagy, Mitophagy and Lysosomal Functions in Modulating Bioenergetics and Survival in the Context of Redox and Proteotoxic Damage: Implications for Neurodegenerative Diseases.

Aging and disease

Aging Dis. 2016 Mar 15;7(2):150-62. doi: 10.14336/AD.2015.0820. eCollection 2016 Mar.

Redox and proteotoxic stress contributes to age-dependent accumulation of dysfunctional mitochondria and protein aggregates, and is associated with neurodegeneration. The free radical theory of aging inspired many studies using reactive species scavengers such as alpha-tocopherol, ascorbate and coenzyme Q...
