A locked 468-gene detoxification panel in Alzheimer's disease brain, liver, and blood: 141 high-confidence cerebral associations including lower CYP46A1 transcript abundance, and a 12-sample hepatic CYP7A1 signal
McCaulley ME.. Research Square, 2026-09-15
Topic: Genetics and APOE
In brain, inverse-variance random-effects meta-analysis (DerSimonian–Laird) across six independent postmortem adult-brain GEO cohorts (GSE33000, GSE132903, GSE173955, GSE159699, GSE5281, GSE48350) yielded 458 analyzable panel genes, 167 at Benjamini–Hochberg FDR < 0.05, and 141 high-confidence genes (FDR < 0.05, measured in at least three cohorts, direction-concordant in at least 70% of cohorts, and nominally significant in at least two cohorts).

Key findings
- In brain, inverse-variance random-effects meta-analysis (DerSimonian–Laird) across six independent postmortem adult-brain GEO cohorts (GSE33000, GSE132903, GSE173955, GSE159699, GSE5281, GSE48350) yielded 458 analyzable panel genes, 167 at Benjamini–Hochberg FDR < 0.05, and 141 high-confidence genes (FDR < 0.05, measured in at least three cohorts, direction-concordant in at least 70% of cohorts, and nominally significant in at least two cohorts).

How this study scored 16/100
Preprint — not yet peer-reviewed. It scored 58 on the same rubric, but non-peer-reviewed sources are capped at 16, so it shows as 16. We have no data on times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 36 of the 62 points we could judge it on, which is 58 out of 100.
| Component | Points | Why |
|---|---|---|
| Journal tier | 2 / 10 | Tier 4 — not a peer-reviewed journal (Research Square) |
| Journal's citation record | 0 / 4 | Not a journal article, so the journal's record does not count |
| Study design | 12 / 12 | A meta-analysis pooling many studies |
| Strength of evidence | 5 / 5 | Rated “high” in our summary |
| Peer-review validation | 4 / 10 | Preprint — not yet peer-reviewed. Hosted on a preprint server. |
| How recent | 5 / 5 | 2026 — within 1 year(s) of the newest study here |
| Sample size | 2 / 4 | 329 participants |
| Effect reported | 2 / 3 | Effect reported as a number, without an interval or test |
| Studied in people | 3 / 3 | Studied in people (participant count stated) |
| Randomised / blinded | 0 / 2 | A review of other studies — randomisation is not credited here |
| Times cited | — / 7 | No citation count (not found in OpenAlex) — left out of this score |
| Citations per year | — / 5 | No citation count or no year — left out of this score |
| Impact for its field and year | — / 6 | No field-weighted citation impact (OpenAlex has none yet) — left out of this score |
| Cited by studies here | — / 6 | Not yet checked against this library's citation graph — left out of this score |
| Still being cited | — / 4 | No yearly citation counts — left out of this score |
| Senior author's track record | — / 4 | Senior author's record not available — left out of this score |
| Institution's track record | — / 3 | No institution listed in OpenAlex — left out of this score |
| Multi-centre collaboration | — / 3 | Institutions not listed — left out of this score |
| Indexed in PubMed | 1 / 2 | Not in PubMed, but has a DOI |
| Free to read | 0 / 2 | Behind a paywall — scores zero |
| Points | 36 / 62 | Scored on 12 of 20 parts. We have no data for the rest, so they are left out: 36 of the 62 points we could judge it on is 58 out of 100. |
| Total | 58 / 100 | Capped to 16 because this is not a peer-reviewed article. |
