Identification of LDH-A as a therapeutic target for cancer cell killing via (i) p53/NAD(H)-dependent and (ii) p53 independent pathways [PDF]

open access: yes, 2014
Most cancer cells use aerobic glycolysis to fuel their growth. The enzyme lactate dehydrogenase-A (LDH-A) is key to cancer’s glycolytic phenotype, catalysing the regeneration of nicotinamide adenine dinucleotide (NAD þ ) from reduced nicotinamide adenine

Can adenine nucleotides predict primary nonfunction of the human liver homograft? [PDF]

open access: yes, 1994
Sixty-eight primary liver grafts were analyzed to see whether adenine nucleotides (AN: ATP, ADP, and AMP) or purine catabolites (PC: adenosine, inosine, hypoxanthine, and xanthine) of tissue or effluent can predict primary graft nonfunction.

Murine iNKT cells are depleted by liver damage via activation of P2RX7

open access: yesEuropean Journal of Immunology, Volume 50, Issue 10, Page 1515-1524, October 2020., 2020
Drug‐induced liver injury activates a suicide pathway in hepatic iNKT cells. The tissue damage induced release of ATP and NAD into the extracellular space triggers the receptor P2RX7 and leads locally to a long‐lasting depletion of iNKT cells. Abstract Invariant natural killer T cells (iNKT) constitute up to 50% of liver lymphocytes and contribute to ...

The ferroelectric Mott-Hubbard phase of organic (TMTTF)2X conductors

open access: yes, 2000
We present experimental evidences for a ferro-electric transition in the family of quasi one- dimensional conductors (TMTTF)2X. We interpret this new transition in the frame of the combined Mott-Hubbard state taking into account the double action of the ...
