In this task, you are given a sentence. You are expected to recognize the name of gene or protein. Although there might be several correct answers, you need to write one of them.

Input: Consider Input:  As immunoglobulin transcription is mainly regulated by the B - cell transcription factors Oct2 and BOB . 1 / OBF . 1 , we analyzed 35 cases of LPHD , 32 cases of cHD , and 2 Hodgkin disease cell lines for the expression of these transcription factors and also in parallel for immunoglobulin expression .

Output: transcription factors


Input: Consider Input:  Regulation of cytokine production in T - cell responses to inhalant allergen : GATA - 3 expression distinguishes between Th1 - and Th2 - polarized immunity .

Output: GATA - 3


Input: Consider Input:  Erythroid Kruppel - like factor ( EKLF ) is a red cell - specific transcriptional activator that is crucial for consolidating the switch to high levels of adult beta - globin expression during erythroid ontogeny .


Output: transcriptional activator
