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: Molecular analysis indicated that inactivation of H - 2L expression in nearly every null clone resulted from an apparent deletion or rearrangement of 5 ' - flanking and 5 ' - coding H - 2L sequences , with breakpoints consistently mapping to within a 550 bp GC - rich region between exon 1 and the middle of intron 2 .

Output: H - 2L

Input: Consider Input: The use of specific somatic cell hybrids have allowed us to locate the YAC contig telomeric to the D3F15S2 locus , in a region which is frequently deleted in lung carcinomas .

Output: D3F15S2 locus

Input: Consider Input: To increase the number of circulating polymorphonuclear neutrophils , the patient was treated with recombinant granulocyte - macrophage colony - stimulating factor ( GM - CSF ) at a dose of 2 micrograms protein / kg bodyweight s . c . / 12 h .
Output: GM - CSF
