Purification and Antitumor Activity of Different Alcohol-Derived Fragment Extracts from Crab Shell.
Article in Asian Pacific journal of cancer prevention : APJCP, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveCrab, a marine animal in the south of Iraq in the Gulf region, has several bioactive ingredients with potential antitumor activity. It is mentioned in Iraqi folklore as medicine with antitumor properties.
methodsThe study examined the anticancer activity of a pharmaceutically active ingredient derived from crab shells, such as chitosan and purified fractions. Shell material was dried in an oven at 200°C. The baked granular powder was extracted by the Methanolic Extraction method and partially purified as fractions. The study included two parts: in vitro testing on several cancer cell lines and in vivo testing against a mammary adenocarcinoma mouse model.
resultsChitosan purified from backed crab shell powder exhibited proliferation inhibition in vitro for two human breast cancer cell lines (AMJ13 and MCF7) and one mouse mammary adenocarcinoma tumor cell line (AMN3). Furthermore, the isolated fractions showed significant cancer cell proliferation inhibition in (Cal51) breast cancer cells and esophageal cancer (SKG). The purified extract showed marked in vivo antitumor activity by significantly reducing tumor growth compared to control untreated groups. Furthermore, It shows no significant toxicity on mice weight by the methanolic extract even when used at a high dose.
conclusionThese results suggest that the chitosan purified from backed crab shell powder and the ethanolic fraction have broad antitumor effects that can be used for cancer treatment in clinical trials.
