Nuclear prothymosin α inhibits epithelial‐mesenchymal transition (EMT) in lung cancer by increasing Smad7 acetylation and competing with Smad2 for binding to SNAI1, TWIST1, and ZEB1 promoters. In early‐stage cancer, ProT suppresses TGF‐β‐induced EMT, while its loss in the nucleus in late‐stage cancer leads to enhanced EMT and poor prognosis.

Immuno-Electron Microscopical Investigations with a New Tracer: Peroxidase-Labeled Protein A: Application for Detection of Pemphigus and Bullous Pemphigoid Antibodies [PDF]
Peroxidase-labeled Protein A, a stable immunoenzyme tracer of high reactivity and comparatively low molecular weight, has been applied in immuno-electron microscopy for detection of bound IgG-type pemphigus and bullous pemphigoid antibodies.

Determination of ADP/ATP translocase isoform ratios in malignancy and cellular senescence
The individual functions of three isoforms exchanging ADP and ATP (ADP/ATP translocases; ANTs) on the mitochondrial membrane remain unclear. We developed a method for quantitatively differentiating highly similar human ANT1, ANT2, and ANT3 using parallel reaction monitoring. This method allowed us to assess changes in translocase levels during cellular

Purification and characterization of peroxidase from date palm cv. Agwa fruits
Purification of peroxidase POII from date palm cv. Agwa fruits were carried out. The molecular mass of POII was 43 kDa. The broad pH optimum of POII at pH’s 6.0–7.0 was detected.

Loss of proton‐sensing GPR4 reduces tumor progression in mouse models of colon cancer
G protein‐coupled receptor 4 (GPR4) is a pH‐sensing receptor activated by acidic pH. GPR4 expression is increased in patients with inflammatory bowel disease who are at high risk of developing colorectal cancer. In mouse models, loss of GPR4 attenuated tumor progression. This correlated with increased IL2 and natural killer cell activity.

Dopamine-D1 and δ-opioid receptors co-exist in rat striatal neurons [PDF]
Cocaine’s enhancement of dopaminergic neurotransmission in the mesolimbic pathway plays a critical role in the initial reinforcing properties of this drug. However, other neurotransmitter systems are also integral to the addiction process.

TRPM8 levels determine tumor vulnerability to channel agonists
TRPM8 is a Ca2+ permissive channel. Regardless of the amount of its transcript, high levels of TRPM8 protein mark different tumors, including prostate, breast, colorectal, and lung carcinomas. Targeting TRPM8 with channel agonists stimulates inward calcium currents followed by emptying of cytosolic Ca2+ stores in cancer cells.
