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

Background: Small cell lung cancer (SCLC) accounts for 15% of all lung cancers and presents early metastasis and poor prognosis. Chemotherapy with cisplatin (CDDP) remains one of the standards of care in first-line treatment. However, the emergence of acquired resistance to CDDP causes disease progression and cancer recurrence. A comprehensive understanding of the CDDP-resistant mechanisms aids in defining accurate biomarkers and developing potential strategies. Methods: The liquid chromatograph mass spectrometer (LC-MS/MS) was conducted to analyze the differential exosomal proteins from plasma samples of SCLC patients with non-treatment or resistance to CDDP. The online RNA-seq data with clinicopathological information on SCLC patients were downloaded from the Gene Expression Omnibus (GEO) database for further prognostic analysis. The SCLC cell line model of acquired CDDP resistance was established to investigate the role of platelet protein multimerin-1 (MMRN1) in CDDP resistance. Results: MMRN1 was increased in CDDP-resistant SCLC patients and cell line models. Reduction of MMRN1 recovered the sensitivity to CDDP while overexpression of MMRN1 conferred CDDP resistance. The CDDP-resistant SCLC cells disseminated resistant to the CDDP-sensitive SCLC cells via the exosomal MMRN1. Additionally, CDDP treatment induces endoplasmic reticulum (ER) stress and subsequent upregulation of MMRN1. Increasing MMRN1 interacted with binding immunoglobulin protein (BiP) in the ER, maintaining the ER stress in SCLC cells. Conclusions: The present study identified exosomal MMRN1 as a potential biomarker for CDDP resistance in SCLC. MMRN1 sustains ER stress via interaction with BiP and subsequently facilitates CDDP resistance, which might be a promising therapeutic target to overcome CDDP resistance.
