Transcriptomic profiling reveals autophagy-associated programs and prognostic biomarkers in anoikis-resistant pancreatic cancer cells.
Article in BMC cancer, 2026. 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
Pancreatic ductal adenocarcinoma (PDAC) is characterized by aggressive metastatic progression and poor clinical outcomes. During metastatic dissemination, detached tumor cells must overcome anoikis, a form of apoptosis induced by loss of extracellular matrix attachment. Although anoikis resistance is considered a critical prerequisite for metastasis, the adaptive mechanisms supporting detached survival in pancreatic cancer remain incompletely understood. In this study, anoikis-resistant (AR) pancreatic cancer cell models were established through repeated long-term suspension culture using Capan-1 and PSN-1 cells. Transcriptomic profiling was performed to identify conserved molecular programs associated with anoikis resistance in PDAC. Gene set variation analysis (GSVA) demonstrated consistent transcriptomic enrichment of autophagy-associated and suppression of cell cycle-related pathways in both AR models. Differential expression and integrative pathway analyses further identified several core genes associated with autophagy regulation and cytokine signaling. Survival analysis revealed that elevated expression of UBC and ATG14 was associated with poor prognosis in pancreatic cancer patients. Our findings suggest that suspension-selected pancreatic cancer cells undergo coordinated stress-adaptive transcriptional remodeling characterized by enriched autophagy- and ubiquitin-associated transcriptional programs.
