It is well known that head and neck squamous cell carcinomas are characterized by genetic alterations, genomic instability and different immune defects and Telomerase reverse transcriptase promoter mutations have been found with high rates in patients with tongue squamous cell carcinomas. We presented a non-smoker, no alcohol consuming woman who had a second primary tongue SCC after four and a half years later of her first tongue SCC with TERT promoter mutation. The primary tumor and its recurrences in woman with tongue SCC who have never smoked and had no alcohol consumption may need to be differing from other tongue carcinomas. TERT promoter mutations may have a relation in etiopathogenesis of tumor and mutations need to be on mind in future studies.

Background: Meningioma represents the most common intracranial tumor in adults. However, it is rare in pediatric patients. We aimed to demonstrate the clinicopathological characteristics and long-term outcome of pediatric meningiomas (PMs).

This study investigates the interrelationship between human telomerase reverse transcriptase (hTERT) and ferroptosis in precursor-B (pre-B) acute lymphoblastic leukemia (ALL), specifically examining how hTERT modulation affects ferroptotic cell death pathways. Given that hTERT overexpression characterizes various cancer phenotypes and elevated telomerase activity is observed in early-stage and relapsed ALL, we investigated the molecular mechanisms linking hTERT regulation and ferroptosis in leukemia cells. The experimental design employed Nalm-6 and REH cell lines under three distinct conditions: curcumin treatment, hTERT siRNA knockdown, and their combination.

The latest World Health Organization (WHO) classification of central nervous system tumors (WHO2021/5th) has incorporated molecular information into the diagnosis of each brain tumor type including diffuse glioma. Therefore, an artificial intelligence (AI) framework for learning histological patterns and predicting important genetic events would be useful for future studies and applications. Using the concept of multiple-instance learning, we developed an AI framework named GLioma Image-level and Slide-level gene Predictor (GLISP) to predict nine genetic abnormalities in hematoxylin and eosin sections: , , mutations, promoter mutations, homozygous deletion (CHD), amplification (amp), 7 gain/10 loss (7+/10-), 1p/19q co-deletion, and promoter methylation.

Background: Isocitrate dehydrogenase (IDH)-mutant gliomas generally have a better prognosis than IDH-wild-type glioblastomas, and the extent of resection significantly impacts prognosis. However, there is a lack of integrated tools for predicting outcomes based on molecular subtypes and treatment modalities. This study aimed to identify factors influencing gross total resection (GTR) rates and to develop a clinical prognostic tool for IDH-mutant gliomas.

Background: Calcific aortic valve disease is the pathological remodeling of valve leaflets. The initial steps in valve leaflet osteogenic reprogramming are not fully understood. As TERT (telomerase reverse transcriptase) overexpression primes mesenchymal stem cells to differentiate into osteoblasts, we investigated whether TERT contributes to the osteogenic reprogramming of valve interstitial cells.
