Antineoplastic Activity of Sodium Caseinate in a Cytarabine-Resistant Mouse Acute Myeloid Leukemia Cell Line.
Article in Nutrients, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundAcute myeloid leukemia (AML) is a hematological neoplasm of rapid and progressive onset, and is the most common form of leukemia in adults. Chemoresistance to conventional treatments such as cytarabine (Ara-C) and daunorubicin is a main cause of relapse, recurrence, metastasis, and high mortality in AML patients. It is known that sodium caseinate (SC), a salt derived from casein, a milk protein, inhibits growth and induces apoptosis in acute myeloid leukemia cells but not in normal hematopoietic cells. However, it is unknown whether SC retains its antileukemic effect in cytarabine-resistant AML cell lines.
objectiveTo evaluate the antineoplastic effect of SC in cytarabine-resistant leukemia models.
methodsThe SC inhibits the growth and induces apoptosis in parental WEHI-3 AML cells. Here, we generated two cytarabine-resistant sublines, WEHI-CR25 and WEHI-CR50, which exhibit 6- and 16-fold increased resistance to cytarabine, respectively, compared to the parental WEHI-3 cells. Thus, these sublines mimic a chemoresistant model.
resultsWe demonstrate that WEHI-CR25 and WEHI-CR50 cells retain sensitivity to SC, similar to parental WEHI-3 cells. This sensitivity results in inhibited cell proliferation, induced apoptosis, and increased expression of ENT1 and dCK, molecules involved in the entry and metabolism of Ara-C, while decreasing MDR1 expression. Additionally, we observed that SC prolonged the survival of WEHI-CR50 tumor-bearing mice, despite their resistance to Ara-C.
conclusionThis is the first evidence that SC, a milk protein, may inhibit proliferation and induce apoptosis in cytarabine-resistant cells.
