Input: Consider Input:  In two lines ( OCI - AML - 1 , OCI - AML - 11 ) , TNF - alpha acted as an apoptotic agent ; in others ( HU - 3 , M - 07e , TF - 1 ) , it had the opposite effect , preventing apoptosis and inducing proliferation .

Output: TNF - alpha


Input: Consider Input:  These later findings indicate that neither homo - nor heterodimer formation is an absolute prerequisite for I kappa B alpha recognition of p65 .

Output: I kappa B


Input: Consider Input:  15 - Deoxy - Delta ( 12 , 14 ) - PGJ ( 2 ) ( 15d - PGJ ( 2 ) ) , a PPAR - gamma agonist , has a dose - dependent antiproliferative and cytotoxic effect on normal and malignant B cells as shown by [ ( 3 ) H ] thymidine and 3 - [ 4 , 5 - dimethylthiazol - 2 - yl ] - 2 , 5 - diphenyltetrazolium bromide assays .


Output: PPAR - gamma
