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:  We have established optimal conditions for the measurement of glucocorticoid receptors ( GR ) in human white cells using a whole - cell binding assay with [ 3H ] dexamethasone as the ligand , and the subsequent determination of the GR content in normal human lymphocytes and in leukemic cells of patients with various forms of acute and chronic leukemia .

Output: glucocorticoid receptors


Input: Consider Input:  This study established a UUO model in angiotensin type 1a receptor ( AT1a ) deficient ( mutant ) mice to elucidate the role of angiotensin II through AT1a on the fibrosis of the obstructed kidney ( OBK ) .

Output: angiotensin II


Input: Consider Input:  No clear correlation could be established between the level of glucocorticoid receptor and the in vitro action of steroids in normal and neoplastic lymphoid tissue .


Output: glucocorticoid receptor
