Description

Cancer Metastasis and Metabolic Reprogramming

  • Ovarian Cancer:

    • Low FAM210B expression correlates with poor survival and metastasis .

    • Loss of FAM210B increases mitochondrial respiration and reduces glycolysis via PDK4 suppression, activating EMT and metastasis .

    • Restoring PDK4 partially reverses invasive phenotypes .

  • Lung Adenocarcinoma (LUAD):

    • Acts as a tumor suppressor by upregulating IFN-α/β, activating STAT1/IRF9/IFIT3 axis .

    • Overexpression inhibits tumor growth (↓Ki67, ↓CD31) and metastasis (↓migration, ↑E-cadherin) .

Erythroid Differentiation and Iron Metabolism

  • Essential for hemoglobinization and mitochondrial iron import during erythropoiesis :

    • Facilitates oligomeric iron transport complex formation for heme synthesis .

    • Knockout models show abnormal erythroid differentiation and ROS accumulation .

    • Paradoxically, adult mice lacking FAM210B retain normal erythroid differentiation, suggesting developmental-stage-specific roles .

Autoimmune Regulation

  • Systemic Lupus Erythematosus (SLE)-like Phenotypes:

    • 15.68% of Fam210b<sup>−/−</sup> mice develop lupus-like autoimmunity (↑anti-dsDNA IgG, splenomegaly) .

    • Mechanistically, knockout increases CD71<sup>+</sup> erythroid cells and ROS, promoting lymphocyte activation .

Therapeutic Implications

  • Cancer: FAM210B restoration or PDK4/TOM70 pathway modulation may counteract metastasis .

  • Autoimmunity: Targeting ROS in CD71<sup>+</sup> erythroid cells could mitigate SLE-like symptoms .

  • Erythropoietic Disorders: Context-specific targeting required due to conflicting adult vs. developmental roles .

Research Gaps and Future Directions

  • Structural Biology: Detailed 3D structure of FAM210B remains uncharacterized.

  • Context-Dependent Localization: Mechanisms underlying inner vs. outer membrane localization require clarification.

  • Therapeutic Development: No small-molecule activators/inhibitors of FAM210B have been reported to date.

Product Specs

Form
Lyophilized powder
Note: While we prioritize shipping the format currently in stock, please specify your preferred format in order notes for customized preparation.
Lead Time
Delivery times vary depending on the purchasing method and location. Please consult your local distributor for precise delivery estimates.
Note: Standard shipping includes blue ice packs. Dry ice shipping requires advance notice and incurs additional charges.
Notes
Avoid repeated freeze-thaw cycles. Store working aliquots at 4°C for up to one week.
Reconstitution
Centrifuge the vial briefly before opening to consolidate the contents. Reconstitute the protein in sterile deionized water to a concentration of 0.1-1.0 mg/mL. For long-term storage, we recommend adding 5-50% glycerol (final concentration) and aliquoting at -20°C/-80°C. Our standard glycerol concentration is 50% and may serve as a reference.
Shelf Life
Shelf life depends on various factors, including storage conditions, buffer composition, temperature, and the protein's inherent stability. Generally, liquid formulations have a 6-month shelf life at -20°C/-80°C, while lyophilized forms have a 12-month shelf life at -20°C/-80°C.
Storage Condition
Upon receipt, store at -20°C/-80°C. Aliquot to prevent repeated freeze-thaw cycles.
