MK2 promotes p16 negative head and neck cancer migration, invasion, and metastasis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
For patients with locally advanced, p16-negative head and neck squamous cell carcinoma (HNSCC), overall survival remains poor due to primary locoregional failure and distant metastasis following curative therapy. We aimed to understand how MAPKAPK2 (MK2) regulates HNSCC tumor cell migration and invasion, important first steps in cancer metastases. The TCGA database and HNSCC tissue microarrays were used to show that MK2 expression was associated with more advanced cancers and faster cancer recurrence rates. We observed that silencing of tumor MK2 in human cell lines (shRNA) caused a significant reduction in tumor cell migration-invasion in a complex HNSCC microphysiologic system used to recapitulate the tumor microenvironment. Murine cells (Ly2) with MK2 silenced (CRISPR-Cas9) also demonstrated reduced migration and invasion using 2D and 3D monoculture cell migration-invasions assays. Ly2 cells are orthotopic p16-negative murine metastatic cells that spontaneously metastasize, and we observed that MK2 inhibition via genetic (Cas9/CRISPR) or pharmacologic (PF-3644022) methods led to a significant reduction in the number of circulating tumor cells, fewer lymph node and lung metastases, and MK2 inhibited mice showed improved overall survival. Our findings suggest that HNSCC MK2 regulates tumor cell migration-invasion and may be a promising therapeutic target to reduce metastases.
