1 · What the graph read from it

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.

2 · The registry

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

Tumor-associated macrophages (TAMs) are important regulators of the complex interplay between immune system and breast cancer. TAMs fuel the cancer progression and metastasis by reprogramming their specific functional phenotype in cancer settings. Therefore, it is important to clarify the mechanisms of shaping specific functional phenotype of macrophages in tumor milieu. LncRNA profiles of TAMs were identified by LncRNA microarray. Flow cytometry was used to detect the surface markers of TAMs. The co-localization among lincRNA-p21, p53 and Mouse Double Minute 2 (MDM2) was identified by FISH probe and immunofluorescence. PyVT-MMTV and BALB/c mice were used for in vivo analysis. In the present work, we found that lincRNA-p21 significantly up-regulated in 4T1 educated macrophages. LincRNA-p21 knockdown facilitated macrophage polarization into pro-inflammatory M1 in tumor microenvironment, which might be caused by MDM2 eliciting proteasome-dependent degradation to p53 and activated NF-κB and STAT3 pathway. TAMs with lincRNA-p21 knockdown induced cancer cell apoptosis, inhibited tumor cell migration and invasion. In vivo, lincRNA-p21 knockdown macrophage adoptive transfer could alleviate breast cancer progression. Our results indicated that lincRNA-p21 was a key regulator of TAMs function in tumor milieu. Our data also shed a light on novel therapeutic targets of tumors characterized by monocytes/macrophages infiltration.
