Researchers discover dysregulation of transfer RNA expression in cancer

A recently published paper in the journal Molecular Cancer by the group of Dr. Manel Esteller, Director of the Josep Carreras Leukaemia Research Institute, ICREA Research Professor and Genetics Chairman at the University of Barcelona, shows that transfer RNAs for certain amino acids are altered at the epigenetic level in some types of cancer, expressing it in an exaggerated manner in some cases and being deficient in others.

Hemoglobin plays role as a chemosensory signal for mother mice to protect offspring

Biochemists in Japan were surprised to discover that the molecule hemoglobin in the blood works not only as an oxygen carrier, but when the blood is spilled as a result of aggression, accident or predator attack, the molecule also acts as a chemosensory signal -; a chemical stimulus picked up by the senses, namely smell in this case -; for lactating mother mice, prompting digging or rearing behavior in them to check the surrounding environment and keep their offspring safe.
