Project description:The lung is a common metastatic site for various cancer types. Successful immune surveillance of lung metastasis depends on Natural Killer (NK) cells, but the underlying mechanisms are elusive. Here, we show that the pulmonary vasculature recruits and maintains highly cytotoxic and differentiated CD11bhigh NK cells through the integrins Lymphocyte Function-associated Antigen 1 (LFA-1) and Very Late Antigen (VLA-4). These NK cells rapidly eradicate metastasizing tumor cells within the vasculature. However, after the initial clearing phase, pulmonary NK cells fail to track extravasated tumor cells and remain intravascular, outside of the emerging nodules. In contrast, metastatic nodules are preferentially infiltrated with bloodborne and less differentiated CD27high NK cells. Within the metastatic lung, CD11bhigh NK cells undergo a rapid impairment of their migratory and cytotoxic features, while the intranodular CD27high subset transitions towards a transforming growth factor β (TGF-β)-driven state with reduced capacity to persist in the tumor tissue. Our findings demonstrate that the compartmentalization of NK cells is key for effective tumor cell surveillance in lung metastasis and that the use of TGF-β-resistant CD27high NK cells might be a novel strategy to enhance local anti-tumor activity.

Project description:Cancer invasion and metastasis are governed by intricate molecular mechanisms. We demonstrate that TRIM27, an E3 ubiquitin ligase, plays dichotomous roles in cancer depending on its subcellular localization, which is controlled by acetylation/deacetylation at K297 independent of its ligase activity. Acetylation by GCN5 directs TRIM27 to the nucleus, while deacetylation by HDAC4 promotes cytoplasmic localization and cell proliferation. Nuclear TRIM27 binds PARP1 and NELFs, represses PARP1-mediated NELFA ADP-ribosylation, maintains RNA polymerase II pausing, and suppresses PAX6 transcription, thereby inhibiting cancer invasion and metastasis.

Project description:Investigation of global gene expression levels between B cells, Natural killer cells and Natural killer B cells Gene expression profiling using sorted B cells, Natural killer cells and Natural killer B cells from WT mouse spleen. Total RNA extracted from WT cells were quantified by the NanoDrop ND-1000 and RNA integrity was assessed by standard denaturing agarose gel electrophoresis. The sample preparation and microarray hybridization were performed based on the NimbleGenâs standard protocols.

Project description:Cancer invasion and metastasis are orchestrated by intricate molecular mechanisms that remain not fully understood. We have identified that the tripartite motif-containing protein 27 (TRIM27), typically known as an E3 ubiquitin ligase, plays dichotomous roles in cancer progression. These roles are determined by its subcellular localization, which is regulated by acetylation and deacetylation at lysine 297 (K297) independently of its ubiquitin ligase activity. Acetylation by general control non-repressed protein 5 (GCN5) directs TRIM27 to the nucleus, where it inhibits cancer cell invasion and metastasis by modulating the transcription of paired box 6 (PAX6). Conversely, deacetylation by histone deacetylase 4 (HDAC4) results in cytoplasmic localization, promoting cell proliferation and tumor growth. In the nucleus, TRIM27 binds to poly (ADP-ribose) polymerase 1 (PARP1) and negative elongation factors (NELFs), repressing PARP1-mediated mono-ADP-ribosylation of NELFA, thereby preventing the release of RNA polymerase II from transcriptional pausing, and leading to transcriptional repression of PAX6. Furthermore, we demonstrate that treatment with the PARP1 inhibitor Olaparib limits the metastasis of cancer cells lacking breast cancer gene (BRCA) mutations, uncovering a previously overlooked therapeutic potential. Importantly, the combination of Olaparib and the HDAC4 inhibitor Tasquinimod synergistically inhibits cancer metastasis. Collectively, these findings reveal a complex interplay of post-translational modifications that dictate the subcellular localization and biological functions of TRIM27, highlighting novel strategies for effective cancer treatment.
