# Dysregulation of Ceruloplasmin, α2-Macroglobulin, and Alpha-2-HS-Glycoprotein in Transfusion-Dependent Thalassemia

## TL;DR

This study finds that three proteins are reduced in thalassemia patients, which may contribute to tissue damage and disease progression due to oxidative stress.

## Contribution

The novel contribution is identifying the dysregulation of CP, A2M, and AHSG in TDT and linking it to oxidative stress and disease progression.

## Key findings

- CP, A2M, and AHSG are downregulated in TDT serum.
- Reduced CP levels disrupt iron and copper metabolism, increasing oxidative stress.
- Low levels of these proteins may lead to red blood cell membrane rupture and tissue damage.

## Abstract

Transfusion-dependent thalassemia (TDT) is a severe inherited anemia characterized by impaired synthesis of hemoglobin chains. Disease progression and TDT severity are potentially linked to oxidative stress and protein damage. This study aimed to explore the expression patterns of ceruloplasmin (CP), α2-macroglobulin (A2M), and alpha-2-HS-glycoprotein (AHSG) in TDT serum through quantitative proteomic profiling. The results were validated using enzyme-linked immunosorbent assays (ELISA). The study participants were divided into three groups based on the duration of blood transfusion. Age and gender-matched normal individuals served as controls. The results revealed the downregulation of these proteins. The reduced levels of these proteins may contribute to tissue damage in TDT patients, primarily due to increased oxidative stress. For example, decreased CP levels can disrupt iron and copper metabolism, leading to heightened oxidative stress and rendering red blood cell membranes more susceptible to rupture due to active oxygen radicals. In summary, CP, A2M, and AHSG association with iron metabolism, inflammation, and oxidative stress underscores their potential relevance in understanding TDT's pathogenesis and progression. These findings may pave the way for improved diagnostic and therapeutic strategies for TDT patients.
