Article Abstract
Familial dementia is a rare inherited disease involving progressive impairment of memory, thinking, and behavior. We report a novel heterozygous pathogenic variant (c.199G > A, p.Val67Ile) in the CIAO1 gene that appears to be co-segregated with Alzheimer's disease in a Japanese family. Biochemical analysis of CIAO1 protein revealed that the variant increases the interaction of CIAO1 with immature amyloid-β protein precursor (AβPP), but not mature or soluble AβPP, indicating plausible CIAO1 involvement in AβPP processing. Our study indicates that a heterozygous variant in the CIAO1 gene may be closely related to autosomal dominant familial dementia.

CIAO1 as a crucial signature gene of cuproptosis in gastric cancer.

Gastric cancer is a global health challenge, necessitating the identification of novel biomarkers and therapeutic targets. The present study aimed to assess the role of cuproptosisrelated genes (CRGs) in gastric cancer, with the goal of establishing a predictive model consisting of key regulators with prognostic significance, thereby enabling the identification of key genes. Data from The Cancer Genome Atlas and Gene Expression Omnibus databases were used to analyze CRGs in stomach adenocarcinoma (STAD).

Cytoplasmic and nuclear iron-sulfur (Fe-S) enzymes that are essential for genome maintenance and replication depend on the cytoplasmic Fe-S assembly (CIA) machinery for cluster acquisition. The core of the CIA machinery consists of a complex of CIAO1, MMS19 and FAM96B. The physiological consequences of loss of function in the components of the CIA pathway have thus far remained uncharacterized.

- Cytoplasmic iron-sulfur assembly (CIA) machinery is crucial for the function of enzymes that maintain and replicate the genome.
- Patients with mutations in a key CIA component experience severe muscle weakness, neurological issues, and other health problems related to iron metabolism.
- Restoring function of this component in affected cells can reverse some of the cellular abnormalities, highlighting its importance in human health and potential role as a disease gene.
Experimental assessment of robust reference genes for qRT-PCR in lung cancer studies.

Stable internal reference genes are crucial for quantitative real-time PCR (qRT-PCR) analyses in lung cancer studies. Widely used reference genes are mostly chosen by intuition or from pan-cancer transcriptome data and lack experimental validation by qRT-PCR in the context of lung cancer. This study evaluated the stability of candidate reference genes in lung cancer cell lines under normal homeostasis, hypoxia, and serum deprivation to screen for robust reference genes for qRT-PCR in lung cancer studies.
