Describe any foreseeable benefit for the included subjects ( Blood sample test for the mir-22 in cancer)?

Solution

Foreseeable benefit for the included subjects ( Blood sample test for the mir-22 in cancer):

MicroRNAs (mir) are small RNAs that are involved in the post-transcriptional regulation of various biological processes. The target of mir-22 is histone deacetylase and is known to have a role in promoting the senescence and growth suppression of the cells and thus, checks the metastasis in the cells. Moreover, the expression level of the mir22 was also reported to be down-regulated in the case of various cancers, except in the case of prostate cancer where it is reported to be upregulated. Due to its lower levels in the blood samples of the cancer patients, tests for the mir22 level is used as the prognosis for cancer.

The mir22 is indeed a tumor suppressor and the information of its level in the blood of the cancer patient would surely help to decide the course of patient care.
