Chemotherapy resistance in acute myeloid leukemia is associated with decreased anti-tumor immune response through MHC molecule and B7 family members.

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
Acute myeloid leukemia (AML) remains challenging due to chemotherapeutic drug-resistance (CDR). Aberrant expression B7 family proteins are involved in tumors evasion. We wonder whether B7 family protein alteration in AML CDR further supports tumor escape. Here, we establish AML cytarabine-resistant cell line U937/Ara-C and report on the expression MHC molecule and B7 family member. HLA-ABC was highly expressed similarly on both cell lines. MIC (MHC class I chain related) A/B and B7-H6 was moderately expressed on the surface of U937 and decreased dramatically by U937/Ara-C. In contrast, enhanced expression of B7-H1 and B7-H7 by U937/Ara-C was observed. HLA-DR and other B7 family members including CD80, CD86, B7-DC, B7-H2, B7-H3, B7-H4, and B7-H5 were not detected by both cell lines. Compared co-cultured with U937, peripheral blood mononuclear cells showed a decreased cytotoxicity when incubated with U937/Ara-C, as indicated by decreased levels of granzyme B and perforin production, accompanied with less TNF-α and lactate dehydrogenase secretion. In conclusion, AML CDR further evades the anti-tumor immune response which may through MHC molecule and B7 family members.
