[HTML][HTML] pH sensing and regulation in cancer

M Damaghi, JW Wojtkowiak, RJ Gillies - Frontiers in physiology, 2013 - frontiersin.org
Cells maintain intracellular pH (pH i ) within a narrow range (7.1–7.2) by controlling membrane
proton pumps and transporters whose activity is set by intra-cytoplasmic pH sensors. …

Drug resistance and cellular adaptation to tumor acidic pH microenvironment

JW Wojtkowiak, D Verduzco, KJ Schramm… - Molecular …, 2011 - ACS Publications
Despite advances in developing novel therapeutic strategies, a major factor underlying
cancer related death remains resistance to therapy. In addition to biochemical resistance, …

Neutralization of tumor acidity improves antitumor responses to immunotherapy

…, AM Weber, K Luddy, M Damaghi, JW Wojtkowiak… - Cancer research, 2016 - AACR
Cancer immunotherapies, such as immune checkpoint blockade or adoptive T-cell transfer,
can lead to durable responses in the clinic, but response rates remain low due to undefined …

Imaging pH and metastasis

AI Hashim, X Zhang, JW Wojtkowiak… - NMR in …, 2011 - Wiley Online Library
Metastasis is a multistep process that culminates in the spread of cells from a primary tumor
to a distant site or organs. For tumor cells to be able to metastasize, they have to locally …

Chronic autophagy is a cellular adaptation to tumor acidic pH microenvironments

JW Wojtkowiak, JM Rothberg, V Kumar, KJ Schramm… - Cancer research, 2012 - AACR
Tumor cell survival relies upon adaptation to the acidic conditions of the tumor microenvironment.
To investigate potential acidosis survival mechanisms, we examined the effect of low …

[HTML][HTML] Chronic acidosis in the tumour microenvironment selects for overexpression of LAMP2 in the plasma membrane

…, MC Lloyd, R Sprung, V Estrella, JW Wojtkowiak… - Nature …, 2015 - nature.com
Early cancers are avascular and hence, profoundly acidic. Pre-malignant cells must adapt to
acidosis to thrive in this hostile microenvironment. Here, we investigate MCF-7 cells that are …

Targeting the metabolic microenvironment of tumors

KM Bailey, JW Wojtkowiak, AI Hashim… - Advances in …, 2012 - Elsevier
The observation of aerobic glycolysis by tumor cells in 1924 by Otto Warburg, and subsequent
innovation of imaging glucose uptake by tumors in patients with PET-CT, has incited a …

Application of evolutionary principles to cancer therapy

PM Enriquez-Navas, JW Wojtkowiak, RA Gatenby - Cancer research, 2015 - AACR
The dynamic cancer ecosystem, with its rich temporal and spatial diversity in environmental
conditions and heritable cell phenotypes, is remarkably robust to therapeutic perturbations. …

Defining cancer subpopulations by adaptive strategies rather than molecular properties provides novel insights into intratumoral evolution

…, M Damaghi, Y Balagurunathan, JW Wojtkowiak… - Cancer research, 2017 - AACR
Ongoing intratumoral evolution is apparent in molecular variations among cancer cells from
different regions of the same tumor, but genetic data alone provide little insight into …

The damaging effect of passenger mutations on cancer progression

CD McFarland, JA Yaglom, JW Wojtkowiak, JG Scott… - Cancer research, 2017 - AACR
Genomic instability and high mutation rates cause cancer to acquire numerous mutations
and chromosomal alterations during its somatic evolution; most are termed passengers …
