STAT6

STAT6 (STAT6)

STAT6 is a STAT transcription factor on the JAK-STAT signaling pathway axis. Validate with UniProt and literature. Indexed under "STAT transcription factors" for antibodies and assay guidance.

Research notes

  • Combine with module neighbors to test non-redundant roles of STAT6.
  • Pair phospho/phenotypic readouts with stimulation and inhibitor controls.
  • Validate antibody clone and compartment; include KD/KO controls.

Assay readouts for STAT6

  • p-STAT6 (Tyr sites, isoform-dependent) and nuclear accumulation.
  • Fractionation or phospho-IF; total STAT controls.
  • SOCS3, IRF9, MX1 transcriptional readouts.
  • Acute vs chronic stimulation kinetics.

STAT6 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 STAT6 studies (examples)

  • Tool lines: HeLa, HepG2, MCF-7, A549, Jurkat—screen by STAT6 expression (CCLE/DepMap).
  • Combine with neighbors (STAT1, STAT2, STAT3, STAT4) via KD/pharmacology.
  • Overexpression/rescue in HEK293T supports mechanism and IP.
  • Isogenic/CRISPR models separate dependency from bypass.

[2] Cell samples for STAT6 Western blot

  • Whole-cell lysates; phosphatase inhibitors for phospho blots.
  • Optimize stimulation time courses per ligand/stress.
  • Controls: KD/KO or inhibitors.
  • BCA normalization; subcellular fractionation when needed.

[3] Tissue samples for STAT6 Western blot

  • Matched tumor/adjacent frozen tissues.
  • Mouse models—mind species cross-reactivity.
  • Primary cells/PDCs when approved.
  • FFPE needs specialized extraction; frozen preferred for phospho.

[4] Cell samples for STAT6 immunoprecipitation

  • Tagged overexpression: HEK293T FLAG/HA-STAT6.
  • Endogenous IP: high-expression lines.
  • Stimulation enriches interactions.
  • Controls: isotype IgG, empty vector, KO.

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

Models & genetics note

Overexpression vs endogenous STAT6 can differ in dosage, splicing, and compartmentation.
