Method for the diagnosis of small cell lung cancer, screening methods and related compositions and systems

摘要

Completely new, cancer (especially small cell lung cancer) object of the present invention to provide a technique for the diagnosis. The problems described above, the present inventors have studied intensively, in the molecular pathways of TSLC1, in particular, (in particular, (over-expressed, changes of sugar chains, such as activation) the expression levels of Rac1 and TSLC1 is, small cell lung carcinoma By found that it is closely related to the development of) and resolved. That is, a change in the activation or sugar, or altered the expression was increased relative to the step of observing the activity of Rac1, or changes in the sugar chains or increased expression of A) TSLC1, and B) and normal individuals by a method comprising the step, showing the expression of do.
