Abstract

Cortical tubers in patients with tuberous sclerosis complex are associated with disabling neurological manifestations, including intractable epilepsy. While these malformations are believed to result from the effects of TSC1 or TSC2 gene mutations, the molecular mechanisms leading to tuber formation, as well as the onset of seizures, remain largely unknown. We used the Affymetrix Gene Chip platform to provide the first genome‐wide investigation of gene expression in surgically resected tubers, compared with histological normal perituberal tissue from the same patients or autopsy control tissue. We identified 2501 differentially expressed genes in cortical tubers compared with autopsy controls. Expression of genes associated with cell adhesion, for example,VCAM1,integrins and CD44, or with the inflammatory response, including complement factors,serpinA3,CCL2 and several cytokines, was increased in cortical tubers, whereas genes related to synaptic transmission, for example, the glial glutamate transporter GLT‐1, and voltage‐gated channel activity, exhibited lower expression. Gene expression in perituberal cortex was distinct from autopsy control cortex suggesting that even in the absence of tissue pathology the transcriptome is altered in TSC. Changes in gene expression yield insights into new candidate genes that may contribute to tuber formation or seizure onset, representing new targets for potential therapeutic development.

  • Gene-expression analysis of tuber tissue has revealed increased expression of astrocyte-enriched genes and prominent neuroinflammation.

    “Indeed, gene-expression analysis of tuber tissue has revealed increased expression of astrocyte-enriched genes and prominent neuroinflammation14,15.”

    From mTORC1 drives cell-autonomous astrocyte reactivity in tuberous sclerosis (2026) · cites this paper as [15]

    The Results (Gene ontology, pathway, and expression analysis; page not provided) report increased expression of immune and inflammatory-response genes in cortical tubers, supporting the neuroinflammation portion of the claim. The passages do not establish increased expression of astrocyte-enriched genes; the reported glial glutamate transporter SLC1A2 was instead lower in tubers. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
