# Summary of key findings across studies #### _Steve Yost_ The table below was generated by ChatGPT 4o after uploading the five papers. ### [ChatGPT thread](https://chatgpt.com/share/679d44a8-7df4-800d-b7e0-790f11cfb58b) The prompts I gave were the following: ``` I've uploaded five papers. What can you find that's common to all the results? Do you see any interesting patterns? ``` It generated key findings in bullet list form for each study. I then prompted: ``` For future reference, please refer to fgene-14-1054558.pdf as Dataset 1 fmars-07-00598.pdf as Dataset 2 fgene-12-795706.pdf as Dataset 3 1-s2.0-S0044848621004944-main.pdf as Dataset 4 1-s2.0-S1050464819311295-main.pdf as Dataset 5 Please create a table summarizing the key findings across studies, with the datasets in order in the column headings ``` ### Caveat: I have not yet validated these summaries by re-examining the papers. | Key Findings | [Dataset 1](https://github.com/Resilience-Biomarkers-for-Aquaculture/Cvirg_Pmarinus_RNAseq/blob/main/analysis_ideas.md#slide-3) | [Dataset 2](https://github.com/Resilience-Biomarkers-for-Aquaculture/Cvirg_Pmarinus_RNAseq/blob/main/analysis_ideas.md#slide-4) | [Dataset 3](https://github.com/Resilience-Biomarkers-for-Aquaculture/Cvirg_Pmarinus_RNAseq/blob/main/analysis_ideas.md#slide-5) | [Dataset 4](https://github.com/Resilience-Biomarkers-for-Aquaculture/Cvirg_Pmarinus_RNAseq/blob/main/analysis_ideas.md#slide-6) | [Dataset 5](https://github.com/Resilience-Biomarkers-for-Aquaculture/Cvirg_Pmarinus_RNAseq/blob/main/analysis_ideas.md#slide-7) | |:---------------------------------------------------------------------------|:--------------------------------------------------------------|:------------------------------------------------------------------|:-----------------------------------------------------------------|:------------------------------------------------------------|:----------------------------------------------------------------------------| | Immune response differences between resistant and susceptible oysters | Disease tolerance mechanisms; immune response trade-offs | Epigenetic and transcriptomic changes in infected oysters | Comparative transcriptomics in C. gigas and C. virginica | Effects of exposure methods on survival and gene expression | Variation in transcriptomic response across families | | Role of Toll-like receptors (TLRs) in immune response | Upregulated in tolerant oysters | No strong correlation with TLR methylation patterns | Expanded and positively selected in C. virginica | TLR4 overexpressed in injected oysters | Differentially expressed in resistant oysters | | C1q domain-containing proteins involved in pathogen recognition | Associated with increased infection tolerance | Found to be differentially expressed under infection | Strongly upregulated in C. virginica | Not a major focus | Upregulated in resistant oysters | | Apoptosis regulation and upregulation of inhibitors of apoptosis (IAPs) | Programmed cell death pathways enriched in tolerant oysters | No clear apoptosis-related methylation effects | Inhibitors of apoptosis (IAPs) upregulated in resistant C. gigas | Injected oysters had higher inflammatory apoptosis response | Resistant oysters showed early apoptotic gene activation | | Oxidative stress and reactive oxygen species (ROS) management | Linked to host survival under high parasite loads | Significant gene expression changes with infection intensity | C. gigas better manages oxidative stress | Injected oysters showed more oxidative stress | Protease inhibitors upregulated in resistant oysters | | Epigenetic modifications (DNA methylation) and gene expression correlation | Transcriptomic rather than epigenetic focus | Higher methylation stability associated with high gene expression | Not examined in this study | Not a focus of this study | Not examined in this study | | Different resistance mechanisms: proteolysis regulation vs apoptosis | Different resistance pathways observed across oyster families | Co-expression network revealed key immune-related genes | Stronger immune activation in susceptible C. virginica | Differences in immune pathway activation based on exposure | Strong early response in resistant families | | Variation in transcriptomic response timing | Stronger responses in tolerant oysters | Response varied with infection intensity | C. gigas responds earlier, more effectively | Injected oysters showed stronger immune responses | Susceptible oysters had weaker early response but strong later inflammation | | Effect of exposure method (injection vs feeding) on immune response | Dose-dependent immune response | Field vs lab differences in expression | Challenge experiments confirm species differences | Injection method led to higher mortality | Controlled infection model used | | Implications for selective breeding (resistance vs tolerance) | Suggests selection for tolerance may be preferable | Epigenetics may not predict long-term infection response | C. gigas naturally resistant; insights for breeding programs | Highlights need for realistic exposure models in breeding | Timing of immune response key for resistance |
