[PDF][PDF] LDHA-associated lactic acid production blunts tumor immunosurveillance by T and NK cells

A Brand, K Singer, GE Koehl, M Kolitzus… - Cell metabolism, 2016 - cell.com
Elevated lactate dehydrogenase A (LDHA) expression is associated with poor outcome in
tumor patients. Here we show that LDHA-associated lactic acid accumulation in melanomas …

[HTML][HTML] Metabolic hallmarks of tumor and immune cells in the tumor microenvironment

K Renner, K Singer, GE Koehl, EK Geissler… - Frontiers in …, 2017 - frontiersin.org
Cytotoxic T lymphocytes and NK cells play an important role in eliminating malignant tumor
cells and the number and activity of tumor-infiltrating T cells represent a good marker for …

[PDF][PDF] Restricting glycolysis preserves T cell effector functions and augments checkpoint therapy

…, EA Rozeman, C Brummer, PJ Siska, K Singer… - Cell reports, 2019 - cell.com
Tumor-derived lactic acid inhibits T and natural killer (NK) cell function and, thereby, tumor
immunosurveillance. Here, we report that melanoma patients with high expression of …

Warburg phenotype in renal cell carcinoma: High expression of glucose‐transporter 1 (GLUT‐1) correlates with low CD8+ T‐cell infiltration in the tumor

K Singer, M Kastenberger, E Gottfried… - … journal of cancer, 2011 - Wiley Online Library
Many tumor cells are characterized by a dysregulated glucose metabolism associated with
increased glycolysis in the presence of oxygen (“Warburg Effect”). Here, we analyzed for the …

The influence of macrolide antibiotics on the uptake of organic anions and drugs mediated by OATP1B1 and OATP1B3

A Seithel, S Eberl, K Singer, D Auge, G Heinkele… - Drug metabolism and …, 2007 - ASPET
Macrolides may cause severe drug interactions due to the inhibition of metabolizing enzymes.
Transporter-mediated uptake of drugs into cells [eg, by members of the human organic …

[HTML][HTML] Double genetic disruption of lactate dehydrogenases A and B is required to ablate the “Warburg effect” restricting tumor growth to oxidative metabolism

…, L Di Ianni, K Dettmer, J Reinders, K Singer… - Journal of Biological …, 2018 - ASBMB
Increased glucose consumption distinguishes cancer cells from normal cells and is known
as the "Warburg effect" because of increased glycolysis. Lactate dehydrogenase A (LDHA) is …

Metabolic plasticity of human T cells: preserved cytokine production under glucose deprivation or mitochondrial restriction, but 2‐deoxy‐glucose affects effector …

…, G Schönhammer, K Peter, K Singer… - European journal of …, 2015 - Wiley Online Library
The strong link between T‐cell metabolism and effector functions is well characterized in the
murine system but hardly investigated in human T cells. Therefore, we analyzed glycolytic …

Lactic acid delays the inflammatory response of human monocytes

K Peter, M Rehli, K Singer, K Renner-Sattler… - Biochemical and …, 2015 - Elsevier
Lactic acid (LA) accumulates under inflammatory conditions, eg in wounds or tumors, and
influences local immune cell functions. We previously noted inhibitory effects of LA on …

[HTML][HTML] New aspects of an old drug–diclofenac targets MYC and glucose metabolism in tumor cells

…, W Gronwald, M Rehli, S Einhell, I Gedig, K Singer… - PloS one, 2013 - journals.plos.org
Non-steroidal anti-inflammatory drugs such as diclofenac exhibit potent anticancer effects.
Up to now these effects were mainly attributed to its classical role as COX-inhibitor. Here we …

The immunological Warburg effect: Can a metabolic‐tumor‐stroma score (MeTS) guide cancer immunotherapy?

PJ Siska, K Singer, K Evert, K Renner… - Immunological …, 2020 - Wiley Online Library
The “glycolytic switch” also known as the “Warburg effect” is a key feature of tumor cells and
leads to the accumulation of lactate and protons in the tumor environment. Intriguingly, non‐…
