WebSIRT1 or Sirtuin 1 is a member of the Silent Information Manager 2 family. SIRT1 is an NAD-dependent histone deacetylase that can deacetylate histones and many non-histone substrates (including p53). It is mainly located in the nucleus of normal cells. However, in cancer cells, it is mainly located in the cytoplasm. WebHerein, we systematically investigated the single-cell transcriptomes of human HCC tissues and found that TREM2 was predominantly expressed by a macrophage subpopulation enriched in tumor tissues that resemble lipid-associated macrophages (LAMs).
