AMP-dependent protein kinase alpha 1 predicts cancer prognosis and immunotherapy response: from pan-cancer analysis to experimental validation.
Article in American journal of cancer research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Pancreatic cancer (PC) has poor prognosis. PRKAA1 (AMPK-α1) is the catalytic subunit of 5'-adenylate-activated protein kinase (AMPK), which plays a critical role in multiple stages of tumorigenesis and development. However, the biological mechanisms of PRKAA1 in the tumor microenvironment have not been well studied. In this study, we performed a combined analysis of data from TCGA and GTEx databases to determine whether PRKAA1 is differentially expressed in a variety of tumors. Kaplan-Meier curve and Cox regression analyses indicated that the differential expression of PRKAA1 affected overall survival in a variety of tumors and was an independent prognostic factor for Brain Lower Grade Glioma (LGG), Brain Lower Grade Glioma (LAML), Liver hepatocellular carcinoma (LIHC), Pancreatic adenocarcinoma (PAAD), and Pancreatic adenocarcinoma (KICH). PRKAA1 was closely associated with various immune profiles, suggesting that PRKAA1 can be used for direct immunotherapy. We investigated the role of PRKAA1 in PC cells. We found that the downregulation of PRKAA1 expression reduced the proliferation, migration, and invasion of PC cells. In addition, we found that PRKAA1 regulated PC progression, possibly through the PI3K/AKT signaling pathway. Treatment of cells with the AKT inhibitors MK2206 and GSK2110183 revealed that the PRKAA1 overexpression group was less sensitive to AKT inhibitors than the negative control group. Taken together, PRKAA1 can be used as a potential prognostic marker and new target for tumor immunotherapy.
