Abstract

MAPK signaling inhibitor (MAPKi) therapies show limited efficacy for advanced thyroid cancers despite constitutive activation of the signaling correlates with disease recurrence and persistence. Understanding how BRAF pathway stimulates tumorigenesis could lead to new therapeutic targets. Here, through genetic and pathological approaches, we demonstrate that BRAF V600E promotes thyroid cancer development by increasing myeloid-derived suppressor cells (MDSCs) penetrance. This BRAF V600E-induced immune suppression involves re-activation of the developmental factor TBX3, which in turn up-regulates CXCR2 ligands in a TLR2-NFκB dependent manner, leading to MDSCs recruitment into the tumor microenvironment. CXCR2 inhibition or MDSCs repression improves MAPKi therapy effect. Clinically, high TBX3 expression correlates with BRAF V600E mutation and increased CXCR2 ligands, along with abundant MDSCs infiltration. Thus, our study uncovers a BRAF V600E-TBX3-CXCLs-MDSCs axis that guides patient stratification and could be targeted to improve the efficacy of MAPKi therapy in advanced thyroid cancer patients.

  • Expression levels of USP15 and TBX3 are significantly increased and positively correlated with tumor progression in thyroid cancer tissue array samples.

    “Across the 152 tissue array samples composed mainly of PTC samples with adjacent tissues, as well as a small number of other types of thyroid cancer tissues, expression levels of USP15 and TBX3 are significantly increased and positively correlated with tumor progression15 (Supplementary Fig. 4a).”

    From Proteostatic reactivation of the developmental transcription factor TBX3 drives BRAF/MAPK-mediated tumorigenesis (2024) · cites this paper as [15]

    The Results section reports that TBX3 was up-regulated and correlated with histological grade in 110 PTC specimens. It does not report USP15 expression or a 152-sample tissue array, so those parts of the attributed claim are unsupported by this paper. (LLM, conf=0.88)

  • Pathologically activated BRAF/MAPK signaling, possibly by BRAFV600E, initiates and promotes tumor development through transcriptionally elevating USP15 and protecting TBX3 from degradation, in addition to directly transcriptionally up-regulating TBX3.

    “Therefore, pathologically activated BRAF/MAPK signaling, possibly by BRAFV600E, initiates and promotes tumor development through transcriptionally elevating USP15 and protecting TBX3 from degradation, in addition to direct transcriptionally up-regulating TBX315.”

  • Upregulation of pioneer developmental organizers such as SOX2, KLF4, β-catenin, SNAIL-1, c-MYC, TBX3, and BCL6 is reported downstream of BRAF/MAPK-driven tumor.

    “Even upregulation of pioneer developmental organizers, such as SOX2, KLF4, β-catenin, SNAIL-1, c-MYC, TBX3, BCL6, et al., are reported downstream of BRAF/MAPK-driven tumor, the pathways causing lineage reprogramming are not clear12,15,30–36.”

    From Proteostatic reactivation of the developmental transcription factor TBX3 drives BRAF/MAPK-mediated tumorigenesis (2024) · cites this paper as [15]

    The Results section, “BRAF/MAPK directs TBX3 expression through AP-1-mediated transcriptional regulation” (page unavailable), reports that BRAF/MAPK activity increases TBX3 expression in papillary thyroid cancer cells. The cited paper supports TBX3 as an example, but the passages do not establish BRAF/MAPK-driven upregulation of the other listed factors. (LLM, conf=0.88)

  • Tbx3 knockout restores differentiation factor expression and renders re-differentiation marked by Tpo, Nis, Tg in BRAFV600E-driven tumors.

    “Tbx3 knockout restored differentiation factors expression and rendered re-differentiation marked with, but not limited to Tpo, Nis, Tg15 (Fig. 7a).”

    From Proteostatic reactivation of the developmental transcription factor TBX3 drives BRAF/MAPK-mediated tumorigenesis (2024) · cites this paper as [15]

    The Discussion says Tbx3 ablation ameliorates the BRAFV600E-associated reduction of thyroid lineage factors, supporting the general differentiation-factor claim. Our copy does not identify Tpo, Nis, and Tg as markers restored by knockout, and the Results report no significant relief of lineage-factor expression after later postnatal Tbx3 knockout. (LLM, conf=0.85)

  • BRAF/MAPK pathway up-regulates developmental factor TBX3 for tumorigenesis by interfering with the proteostasis module in addition to transcriptional regulation.

    “Therefore, BRAF/MAPK pathway up-regulates developmental factor TBX3 for tumorigenesis by interfering with the proteostasis module in addition to transcriptional regulation15”

    From Proteostatic reactivation of the developmental transcription factor TBX3 drives BRAF/MAPK-mediated tumorigenesis (2024) · cites this paper as [15]

    The Results section, “BRAF/MAPK directs TBX3 expression through AP-1-mediated transcriptional regulation” (page unavailable), supports BRAF/MAPK-driven TBX3 up-regulation through AP-1 transcriptional activation. The Discussion links TBX3 activation to thyroid tumor initiation. Neither passage supports the additional claim that BRAF/MAPK interferes with a proteostasis module to up-regulate TBX3.

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.
