Protein Palmitoylation as a Molecular Switch Linking Regulated Cell Death and Disease.
Review in Biomolecules, 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
Regulated cell death is essential for tissue homeostasis, immune defense, and disease progression, yet the lipid-based regulatory mechanisms that coordinate cell death signaling remain incompletely understood. Protein palmitoylation is a dynamic and reversible lipid post-translational modification that controls protein membrane association, trafficking, stability, and signaling complex assembly. This review summarizes the regulatory roles of palmitoylation and depalmitoylation in major forms of regulated cell death, including apoptosis, necroptosis, pyroptosis, ferroptosis, and autophagy-related cell death. Particular attention is given to representative palmitoylated substrates, including Fas cell surface death receptor (Fas), receptor-interacting protein kinase 1 (RIPK1), NLR family pyrin domain containing 3 (NLRP3), gasdermin D (GSDMD), glutathione peroxidase 4 (GPX4), solute carrier family 7 member 11 (SLC7A11), autophagy-related 16 like 1 (ATG16L1), and Beclin1. These substrates illustrate how palmitoylation links membrane organization, metabolic status, inflammatory signaling, and cell fate decisions. Disease-oriented evidence further indicates that dysregulated palmitoylation contributes to cancer, neurodegenerative diseases, and inflammatory or immune-related disorders by modulating cell death resistance, inflammatory amplification, immune evasion, or impaired proteostasis. Current challenges include limited quantitative information on palmitoylation dynamics, incomplete evidence for some enzyme-substrate relationships, and insufficient distinction between disease-driving and secondary palmitoylation events. Targeting zinc finger Asp-His-His-Cys (zDHHC) palmitoyl acyltransferases, depalmitoylating enzymes, or specific palmitoylated substrates may provide new therapeutic opportunities. Overall, this review positions protein palmitoylation as a dynamic molecular switch linking lipid metabolism, membrane signaling, regulated cell death, and disease remodeling.
