Identification of CTHRC1 as a novel candidate for neurodevelopmental disorders
1School of Computer Science and Engineering, Central South University, Changsha, China.
Background:
Cognitive dysfunction affects over 50 million individuals worldwide, with Alzheimer's disease (AD) representing two-thirds of cases. We identified CTHRC1 (Collagen Triple Helix Repeat Containing 1) as a novel candidate associated with cognitive function and neurodegeneration.
Methods:
Human proteomic analysis revealed CTHRC1 as highly upregulated in AD patients (~5-fold increase, adj. p = 0.05), with corresponding elevation in 5xFAD mice. Single-cell RNA sequencing showed predominant astrocyte and oligodendrocyte progenitor expression. Using BXD mice, systems genetics analysis revealed associations between hippocampal CTHRC1 expression and 22 cognition-related phenotypes. PheWAS, ePheWAS, and GWAS analyses confirmed links to nervous system and AD-related traits.
Results:
eQTL mapping identified CTHRC1 as cis-regulated in hippocampus, and correlating with protein transport, transcription, and neurodegeneration pathways. Network analysis revealed 17 direct interactors, including key neurodegeneration genes (BACE1, NEFL, IRS1, VDAC1, SNCAIP) connecting CTHRC1 to core AD pathways (APP, MAPT, APOE, PSEN1/2). CTHRC1 overexpression in SH-SY5Y cells promoted tau degradation and modulated network partner expression.
Conclusion:
CTHRC1 represents a central hub in cognitive function networks, suggesting therapeutic potential for neurodegenerative disorders.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
