Cysteine protease cathepsin-B has been implicated in various human malignancies and is involved in malignancy progression and metastasis. This study aimed to evaluate the circulating levels of cathepsin-B, interleukin-6 (IL-6), and CA15-3, a cancer antigen, as biomarkers for tumors in women with both localized and metastatic BC. The study employed a case-control design, enrolling 108 participants categorized into three groups: healthy individuals, those with localized BC, and those with metastatic BC. The relative mRNA expression of cathepsin-B in blood samples was assessed using qRT-PCR. Additionally, serum levels of IL-6 and CA15-3 were quantified using ELISA. The relative mRNA expression of cathepsin-B, IL-6 levels, and CA15-3 levels were significantly higher in metastatic BC cases than in localized BC cases and the control group (p-value < 0.001). A statistically significant positive correlation was also found between cathepsin-B and both IL-6 and CA15-3 (r = 0.905, r = 0.667, and p < 0.001), respectively. The findings indicate a strong correlation between the interaction of the proteolytic enzyme cathepsin-B and IL-6 with the unfavorable prognosis of BC. This relationship may serve as a potential indicator and a promising target for therapy in BC treatment.","PeriodicalId":39112,"journal":{"name":"Egyptian Journal of Medical Human Genetics","volume":"37 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142177519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Polymorphism in the LCN2 gene is linked to various diseases such as cardiovascular disease, renal damage, and colorectal and pancreatic cancer. Identifying deleterious functional non-synonymous SNPs in the LCN2 gene is crucial in understanding how these genetic variations affect its structure and function. Several in silico tools such as SIFT, Polyphen-2, PROVEAN, PREDICT SNP, MAPP, and SNAP2 followed by I-MUTANT 2.0, MUpro, ConSurf, and NetsurfP-2.0, secondary structure of the protein by SOPMA and PSIPRED, while its interaction with other genes and proteins was analyzed using GeneMANIA and STRING, respectively, and AlphaFold for protein's 3D structure prediction. The study identified 6 potentially harmful nsSNPs (rs11556770, rs139418967, rs142623708, rs200107414, rs201365744, rs368926734) and their structure and function were analyzed using prediction tools. I-MUTANT 2.0 predicted an increase in stability with the nsSNPs rs139418967, while the other shows decrease in protein stability with the 6 nsSNPs (rs11556770, rs139418967, rs142623708, rs200107414, rs201365744, rs368926734) which was validated using MUpro. ConSurf identified the 6 high-risk nsSNPs to be in the conserved regions of the protein. The result showed that rs11556770, rs139418967, rs142623708, rs200107414, rs201365744, and rs368926734 were found to be highly conserved and the variant amino acids.

However, the exact nature of this relationship requires further investigation to be fully elucidated. Genetic links between T1D/T2D and GCA were explored using data from genome-wide association studies available to the public, focusing on populations of European ancestry. We applied a bidirectional mendelian randomization (MR) approach to assess the potential association between these diseases. Confirmatory analyses, including additional datasets and a comprehensive meta-analysis, were utilized. The inverse-variance-weighted (IVW) method was applied to pinpoint heterogeneity and pleiotropy, while subsequent sensitivity analyses aimed to trace the origins of any heterogeneity. Initial analysis demonstrated a correlation between T1D and an elevated likelihood of developing GCA (IVW odds ratio = 1.33, with a 95% confidence interval of 1.22–1.46, and a P-value of 9.42E−10). The causal association was verified through four validation datasets and meta-analysis (all P-value < 0.001). However, the reverse MR analysis was unable to detect any genetic basis for the increased risk of T1D due to GCA. Furthermore, we could not establish any causal links between T2D and GCA. T1D patients may have a higher risk of developing GCA, whereas an inverse causal relationship was not evident. Furthermore, no causal relationship was detected between T2D and GCA. These insights shed light on the possible pathological mechanisms underlying GCA and may influence the future clinical handling of both T1D and GCA.","PeriodicalId":39112,"journal":{"name":"Egyptian Journal of Medical Human Genetics","volume":"22 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141937882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Coronavirus disease 2019 (COVID-19) frequently presents with complications such as respiratory distress, systemic inflammatory responses, and damage to various organs. Several studies have investigated the relationship between COVID-19 and mortality in patients with liver cancer, but there are few research on the relationship between them. This study is to explore the correlation between the two diseases and drugs treating them. The Gene Expression Omnibus (GEO) database provides gene datasets of COVID-19 patients and HCC patients. Through differential gene analysis and weighted gene co-expression network analysis, we determined 223 genes represented in HCC and COVID-19. We then used functional annotation, protein–protein interaction network construction, predictive model development and verification, prognostic value analysis, and miRNA–gene network construction. Besides, we created a drug–hub–gene network by predicting possible medications that interact with hub genes using the Drug–Gene Interaction Database (DGIdb). Ultimately, we applied immunohistochemistry to ascertain the hub genes expression. This study revealed that eight core genes (RRM2, TPX2, DTL, CDT1, TYMS, CDCA5, CDC25C, and HJURP) co-existed in both HCC and COVID-19 and were differentially expressed in both HCC and normal tissues.CDC25C, RRM2, CDCA5, and HJURP had diagnostic value (AUC > 0.8) and prognostic value (adjusted P-value < 0.05). Genome enrichment analysis indicated that eight genes may function in liver cancer through engagement in the cell cycle, DNA replication, etc. In liver cancer samples, these genes were significantly and adversely associated with plasma cells while RRM2 was positively associated with neutrophil and NK cell activation and with dendritic cell resting. Using the miRNAnet database and DGIdb, 9 transcription factors, 7 miRNAs, and 51 drugs or molecular compounds were predicted to interact with the hub genes. Finally, RRM2 expression showed significant variation in clinical specimens, and analysis of the association of RRM2 with immunomodulators indicated that RRM2 was closely connected to MICB and CD276. Our study revealed several metabolic genes related to HCC and COVID-19. Moreover, potential drugs related to central genes were predicted. These findings may provide new ideas for treating COVID-19 and HCC.","PeriodicalId":39112,"journal":{"name":"Egyptian Journal of Medical Human Genetics","volume":"154 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141937885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Egyptian cohort of patients with GD is specifically different regarding the prevalence of type 3 as well as the severity and progression of the disease. The unavailability of precise diagnostic tests and lack of awareness among clinicians are the current challenges associated with diagnosing and managing GD in Egypt. An expert panel meeting was convened with 19 experts from Egypt to address the current unmet challenges in the diagnosis and management of GD from the region and to develop country-specific diagnostic algorithms based on the existing literature for pediatric and adult groups. In addition, management strategies and preventive measures were also discussed. The algorithms presented in this review can be implemented in clinical practice for the timely diagnosis of patients with GD in Egypt. Early diagnosis is crucial in selecting the best treatment for patients with GD, and evidence suggests that early initiation of therapy can result in better outcomes.

This homodomain transcription factor is a central regulator of cardiac development and is expressed in both the first and second heart fields (FHF and SHF). Mutations in the NKX2-5 gene have been linked to sporadic cases of congenital heart disease (CHD), making it a significant target for research and study. While several studies have been conducted on Caucasian populations, there is a dearth of knowledge on the effects of NKX2-5 gene mutations in other settings, underscoring the need for further investigation. Due to differences in geographical and ancestral origin, we hypothesize that mutations may vary across different populations. Understanding the genetic factors that cause CHD is essential for providing effective genetic counseling and developing strategies for risk reduction. Additionally, identification of NKX2-5 mutations in individuals with CHDs is crucial because patients with CHDs are at a higher risk of progressive conduction disease and sudden cardiac death, and genetic information is taken into consideration while making decisions regarding pacemakers and implantable cardiac defibrillators. To determine the risk of congenital heart disease among infants, we conducted a study where we sequenced the exon 1 and exon 2 of NKX 2.5 in patients with sporadic CHDs, with the aim of identifying mutations in the NKX2.5 gene. In this study, a novel frame-shift disease-causing mutation was discovered in patients with atrial-ventricular septal defect. The mutation, identified as c95_95 del A; cDNA.369–369 delA; g 369–369 delA, resulted in the substitution of phenylalanine to leucine (F295L), which in turn caused a truncated NKX2.5 protein. In addition, a non-synonymous mutation, g 316C > T; cDNA 316C > T leucine to arginine (L37R) substitution, was found in a patient with the tetralogy of Fallot, affecting protein function. Furthermore, a novel non-synonymous mutation identified as g 2295–2298; cDNA 755–758 delins AGGG, was predicted by mutation taster to be disease-causing in a ventricular septal defect. It is worth noting that none of these mutations were found among the control subjects, highlighting their potential significance in the pathogenesis of these cardiac defects. Mutations in the NKX2.5 gene are associated with congenital heart diseases and provide molecular insight into the pathogenesis of congenital heart diseases. We recommend that patients with NKX2.5 mutations have periodic screening for cardiac conduction abnormalities and be evaluated for potential implanted cardiac defibrillators and pacemakers.","PeriodicalId":39112,"journal":{"name":"Egyptian Journal of Medical Human Genetics","volume":"49 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141866646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whole-exome sequencing and subsequent Sanger sequencing confirmed a pathogenic mutation in the TGFBRI gene (NM_004612.4: c.605C > T; p.Ala202Val). She refused to receive surgery and died one month later. To our knowledge, this is the first documented case of the TGFBR1 gene mutation who suffered from abdominal aortic aneurysm complicated by descending thoracic aortic dissection. Her rapid death underscores the importance of timely intervention in TGFBR1 mutation-positive patients.","PeriodicalId":39112,"journal":{"name":"Egyptian Journal of Medical Human Genetics","volume":"74 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141866644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
