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.

Example Input:  Deregulation of bcl - 6 expression by chromosomal rearrangements and point mutations of the bcl - 6 promoter region are implicated in the pathogenesis of B - cell lymphoma .
Example Output: bcl - 6

Example Input:  We have used [ 3H ] dexamethasone - 21 - mesylate to label covalently glucocorticoid receptors in rat thymic lymphocytes and in neoplastic cells obtained from patients with acute lymphoblastic leukemia and malignant lymphoma .
Example Output: glucocorticoid receptors

Example Input:  Approximately 35 % of the glucocorticoid receptors can be labeled covalently when intact thymocytes are treated with 100 nM [ 3H ] dexamethasone - 21 - mesylate for 30 min at 4 degrees .
Example Output:
glucocorticoid receptors
