NR6A1

Nuclear receptor subfamily 6 group A member 1 (NR6A1)

NR6A1 is a Nuclear receptor / transcriptional control on the endocrine & hormone axis. Orphan nuclear receptor that binds to a response element containing the sequence 5'-TCAAGGTCA-3' (PubMed:26769970). Acts as a regulator of embryonic stem cell pluripotency by mediating repression of POU5F1/OCT4: binds to the DR0 element within the POU5F1/OCT4 promoter and inhibit… It is indexed under "Nuclear receptor superfamily (major members)" on our pathway page for antibodies, inhibitors, and assay guidance.

Research notes

  • Combine with other genes in the same hub block via genetics or pharmacology to test non-redundant roles of NR6A1.
  • For nuclear receptors pair ligands, co-regulators, and reporter assays; for membrane receptors note GPCR/RTK downstream and desensitization.
  • Verify antibody clone, phospho-site, and stimulation; include KD/KO or inhibitor controls.

Assay readouts for NR6A1

  • Reporter / ChIP: NR6A1 promoter-luciferase or ChIP-qPCR.
  • Ligand treatments: estrogen/androgen/progesterone/glucocorticoid as appropriate.
  • Co-regulators: SRC/p300 co-activator or co-repressor co-IP.
  • Tumor specimens: receptor IHC with mutation/amplification annotation.

NR6A1 experimental notes

Examples below reflect common literature and public resources (e.g., CCLE, DepMap)—validate genotypes, expression, and passage in your own stocks before committing assays.

[1] Cell lines commonly used for NR6A1 studies (examples)

  • Tool lines: MCF-7, T47D, LNCaP, MDA-MB-231, HEK293T—screen by NR6A1 expression and pathway context (CCLE/DepMap).
  • Combine with neighbors (NR0B1, NR0B2, THRA, THRB) via KD/pharmacology to test non-redundancy.
  • Overexpression/rescue in HEK293T supports mechanism and IP workflows.
  • Isogenic/CRISPR models separate pathway dependency from bypass survival.

[2] Cell samples for NR6A1 Western blot

  • Whole-cell lysates—optimize RIPA/NP-40 per antibody; phosphatase inhibitors for phospho blots.
  • Stimulation: serum starvation ± insulin/EGF or amino-acid withdrawal/refeed as relevant.
  • Controls: siRNA/shRNA, CRISPR KO, or inhibitors to validate band specificity.
  • Loading: BCA normalization; subcellular fractionation when needed.

[3] Tissue samples for NR6A1 Western blot

  • Matched tumor/adjacent frozen tissues after pathology review.
  • Mouse GEMM or xenografts—mind species antibody cross-reactivity.
  • Primary cells/PDCs when ethically approved.
  • FFPE needs specialized extraction; frozen tissue preferred for phospho work.

[4] Cell samples for NR6A1 immunoprecipitation

  • Tagged overexpression: HEK293T FLAG/HA-NR6A1 for complex capture.
  • Endogenous IP: high-expression lines; often ≥1–5×10⁶ cells per IP.
  • Stimulation: ligand or nutrient treatments enrich interactions—pilot time courses.
  • Controls: isotype IgG, empty vector, KD/KO negatives.

Human tissues and primary cells require ethics/IRB approval; tumors are heterogeneous—record histotype, site, and preservation conditions.

Models & genetics note

Overexpression vs endogenous NR6A1 can differ in dosage, splicing, and compartmentation—in organoids/PDX, record passage, matrix, and drug history.
