Example Sentences

Earlier proteome analyses had shown, moreover, that Rab7a is a potential interaction partner of TPC2.

From Science Daily

Using modern methods such as endolysosomal patch-clamp electrophysiology and the measurement of lysosomal calcium release via fluorescence microscopy, the researchers established that there was indeed an interaction between Rab7a and TPC2 at the functional level, which promoted the growth and invasiveness of melanoma cells.

From Science Daily

A particularly notable finding, according to the researchers, was that effects of the interaction of Rab7a and TPC2 could be demonstrated in vivo.

From Science Daily

"The interaction between Rab7a and TPC2 could pave the way for new therapeutic strategies which target the specific signaling pathways that promote melanoma growth and metastasis" concludes Grimm.

From Science Daily

Chronic wasting disease is caused by a misfolded protein known as a prion and can be transmitted through predator and prey interaction, such as a panther eating a deer that has the disease.
