HSD11B2

11-beta-hydroxysteroid dehydrogenase type 2 (HSD11B2)

HSD11B2 is a Steroidogenic enzyme on the endocrine & hormone axis. Catalyzes the conversion of biologically active 11beta-hydroxyglucocorticoids (11beta-hydroxysteroid) such as cortisol, to inactive 11-ketoglucocorticoids (11-oxosteroid) such as cortisone, in the presence of NAD(+) (PubMed:10497248, PubMed:12788846, PubMed:17314322, PubMed:22796… It is indexed under "Steroidogenesis & steroid-metabolizing enzymes (gonadal/adrenal)" 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 HSD11B2.
  • 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 HSD11B2

  • Enzyme / metabolomics: steroid intermediates at the HSD11B2 step.
  • H295R / primary adrenals: ACTH or cAMP time courses.
  • Localization: mitochondrial STAR transfer or ER P450.
  • Endocrine phenotypes: cortisol/aldosterone/sex-steroid panels.

HSD11B2 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 HSD11B2 studies (examples)

  • Tool lines: H295R, NCI-H295R, BeWo, MA-10, HEK293T—screen by HSD11B2 expression and pathway context (CCLE/DepMap).
  • Combine with neighbors (STAR, CYP11A1, CYP11B1, CYP11B2) 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 HSD11B2 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 HSD11B2 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 HSD11B2 immunoprecipitation

  • Tagged overexpression: HEK293T FLAG/HA-HSD11B2 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 HSD11B2 can differ in dosage, splicing, and compartmentation—in organoids/PDX, record passage, matrix, and drug history.
