Myosin Vb as a tumor suppressor gene in intestinal cancer.
Article in Oncogene, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Colorectal cancer causes >900,000 deaths every year and a deeper understanding of the molecular mechanisms underlying this disease will contribute to improve its clinical management and survival. Myosin Vb (MYO5B) regulates intracellular vesicle trafficking, and inactivation of this myosin disrupts the polarization and differentiation of intestinal epithelial cells causing microvillous inclusion disease (MVID), a rare congenital disorder characterized by intractable life-threatening diarrhea. Here, we show that the loss Myosin Vb interfered with the differentiation/polarization of colorectal cancer cells. Although modulation of Myosin Vb expression did not affect the proliferation of colon cancer cells, MYO5B inactivation increased their migration, invasion, and metastatic potential. Moreover, Myo5b inactivation in an intestine-specific knockout mouse model caused a >15-fold increase in the number of azoxymethane-initiated small intestinal tumors. Consistently, reduced expression of Myosin Vb in a cohort of 155 primary colorectal tumors was associated with shorter patient survival. In conclusion, we show here that loss of Myosin Vb reduces polarization/differentiation of colon cancer cells while enhancing their metastatic potential, demonstrating a tumor suppressor function for this myosin. Moreover, reduced expression of Myosin Vb in primary tumors identifies a subset of poor prognosis colorectal cancer patients that could benefit from more aggressive therapeutic regimens.
