Objective: . Despite the establishment of a link between telomere status and carcinogenesis, lack of a consensus in the cancer specific pattern of telomere length has a severe impact on the use of relative telomere length (RTL) in cancer diagnosis. The disparity in assessing the relationship between telomere length and cancer risk is complex and may vary as it is influenced by other factors. The objective of this study is to thoroughly examine the intricate relationship between telomere length and cancer incidence in Papillary Thyroid Cancer (PTC) depending on the tumor type, stage, patients' sex and age. Therefore, the current study is focused on the association of RTL in PTC patients with different clinicopathological characteristics and compared with controls to determine the risk of PTC and expected survival time after surgery.
Method: . This study included 126 patients with PTC and 80 controls. RTL in thyroid tissues was measured using quantitative (q) PCR. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using logistic regression analysis. Kaplan-Meier and Cox regression were used to analyze postsurgical outcomes.
Result: . The RTL of patients was significantly shorter than that of controls. A short RTL was significantly correlated with an elevated risk of PTC in patients aged ≥ 55 years, female sex, classic subtype, and tumor size > 2 cm. A short RTL did not affect the overall survival of patients with PTC; however, it was associated with poor survival in patients with tumor size > 2 cm and tumor invasion.
Conclusion: . This unique study combines the use of RTL with various clinicopathological features of patients with PTC. In conclusion, RTL is a promising tumor marker that correlates with the clinical characteristics of patients with PTC. Specifically, RTL < 0.6 could be used with age, sex, tumor size > 2 cm and tumor invasion to predict the risk of PTC development and prognosis of the disease. This study will open new horizon in the use of molecular marker such as RTL for understanding its association with increased cancer risk in patients with different clinicopathological features.

Batrachochytrium dendrobatidis (Bd) is responsible for mass extinctions and extirpations of amphibians, mainly driven by the Global Panzootic Lineage (BdGPL). BdGPL isolate JEL423 is a commonly used reference strain in studies exploring the evolution, epidemiology and pathogenicity of chytrid pathogens. These studies have been hampered by the fragmented, erroneous and incomplete B.

Telomerase, an enzyme crucial for maintaining telomere length, plays a critical role in cellular immortality and is overexpressed in most cancers. This ubiquitous presence makes telomerase, and specifically its catalytic subunit, human telomerase reverse transcriptase (hTERT), an attractive target for cancer immunotherapy. This review explores the development and application of telomerase-based vaccines, focusing on DNA and peptide-based approaches.

: Human fetal liver hematopoietic stem cells have proven potential as therapeutics but lack extensive research due to their limited supply. Even expanded fetal liver hematopoietic stem cells enter senescence or lose their self-renewal capacity after a few days in culture. The present study aimed to obtain a homogeneous and persistent supply of hematopoietic stem cells from the fetal liver by establishing a cell line through immortalization of cells by enhancing telomerase activity.

Interaction between host genotoxic changes and mucosa-associated microbiome (MAM) dysbiosis may have a role in various digestive cancers. We investigated MAM in Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC) progression sequence and its association with host genotoxic changes. 16S rRNA gene sequencing was performed in three different groups of biopsies from nonneoplastic BE from patients without cancer (N, normal group; n = 47) and with EAC (ADJ, adjacent group; n = 27).
