Activating RET point mutations gives rise to the inherited cancer syndrome multiple endocrine neoplasia type 2 (MEN2), characterized by medullary thyroid carcinoma. There are two MEN2 subtypes, MEN2A and MEN2B, that differ in tumour aggressiveness and the associated constellation of other disease features, which are caused by distinct patterns of RET amino acid substitution mutations. MEN2A-RET mutations affecting extracellular cysteine residues promote ligand-independent dimerization and constitutive RET activity, while MEN2B is caused by a single amino acid change in the tyrosine kinase domain of RET, releasing autoinhibition and producing a more active MEN2B-RET kinase that can promote signalling as monomers or dimers in the absence of a ligand. These mutations cause intrinsic biochemical changes in the RET structure and activation but also trigger extrinsic effects that alter RET cellular location, interactions and mechanisms of downregulation that can prolong or mislocate RET activity, changing or enhancing functional outcomes. Furthermore, changes in specific combinations of RET-mediated effects associated with different mutations give rise to the distinct MEN2 disease phenotypes. Here, we discuss the current understanding of the intrinsic and extrinsic characteristics of RET MEN2A cysteine and MEN2B mutants and how these contribute to transforming cellular processes and to the differences in tumour progression and disease aggressiveness.","PeriodicalId":93989,"journal":{"name":"Endocrine-related cancer","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142515228","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}

Additionally, protein levels were quantified in tissue samples from the Kolling Institute of Medical Research's tumor bank. Our results demonstrated that among all miRNA processing components, AGO2 exhibited significant overexpression in ACC compared to the normal adrenal cortex and benign adrenal adenoma (P < 0.001). Kaplan-Meier survival analysis indicated that higher AGO2 expression correlated with significantly worse overall survival in ACC patients (HR: 7.07, P < 0.001). Among 32 cancer types in TCGA, the prognostic significance of AGO2 was most prominent in ACC. This study is the first to report AGO2's potential as a diagnostic and prognostic biomarker in ACC, emphasizing its significance in ACC pathogenesis and potential application as a non-invasive liquid biopsy biomarker.","PeriodicalId":93989,"journal":{"name":"Endocrine-related cancer","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11623120/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142484030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We sought to determine the impact of age on genomic alterations and immune cell composition in papillary thyroid cancer (PTC). Genomic alterations, immune cell composition, and clinical data were obtained using The Cancer Genome Atlas and computational immunogenomic analyses. Disease severity was recoded into three groups: Group A (T1-2N0M0), Group B (T1-3N1a-1bM0), and Group C (T4NxMx or TxNxM1). Histopathologic subtypes included conventional, follicular-variant, and tall cell variant PTC. Spearman's rank correlation, ANOVA, t-test, and multivariable linear regression were performed. A total of 470 PTC samples were retrieved from the TCGA portal with genomic alteration and immune cell composition data. TERT promoter alterations were more common in patients aged ≥65 years (26% vs 4%, P < 0.0001). Tumor mutational burden increased with increasing age (r = 0.463, P < 0.0001). Increasing age was associated with decreased CD8+ T cells (r = -0.15, P = 0.01) using CIBERSORT and decreased B cells (r = -0.13), CD8+ T cells (r = -0.19), and neutrophils (r = -0.14, P < 0.05) using TIMER. Multivariate regression found that increasing age was independently associated with increased resting NK cells and resting dendritic cells, and decreased naïve B cells and CD8+ T cells (P < 0.05). PTC tumors of older adults are characterized by increased TERT promoter alterations, increased tumor mutational burden, and a decreased cytotoxic CD8+ T cells and increased resting dendritic cell immune infiltrate. Further studies are needed to determine if these changes in immune cell infiltrate are associated with compromised outcomes.","PeriodicalId":93989,"journal":{"name":"Endocrine-related cancer","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11608430/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142309472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our study evaluated the utility of cfDNA in advanced thyroid cancers. Patients aged >18 years with metastatic medullary thyroid cancer (MTC), poorly differentiated thyroid cancer (PDTC), or anaplastic thyroid cancer (ATC) were enrolled in this prospective study between 2020 and 2024. As part of standard care, sequencing of germline and tumoral DNA was conducted, and patients with germline mutations were excluded from the study. Whole blood samples were collected in Streck cell-free DNA BCT tubes, cfDNA was extracted from plasma using the EZ1and2 ccfDNA kit and EZ2 Connect. The extracted cfDNA was then sequenced across 50 key cancer-related genes using the Oncomine Precision Assay (OPA) panel on an Ion Torrent Genexus Integrated Sequencer. Forty patients were included; 27 MTC, 2 ATC and 11 PDTC. Tumoral mutations were detected in 36 of the included patients (90%): cfDNA detected mutations in 18/36 patients (13 MTC, 1 ATC, 4 PDTC (50%). Sensitivity of cfDNA was 86% (6/7) pre TKI therapy, and reduced to 54% on therapy (13/24), suggestive of lack of tumor-derived DNA shedding with strong on-target treatment efficacy. Median cfDNA concentration was higher in samples with a detected mutation than those without, 11.91 ng/ml vs 5.81 ng/ml respectively. While an increasing cfDNA was associated with worse progression free survival (p < 0.01). cfDNA is a novel biomarker with potential to monitor disease progression in patients with advanced thyroid cancers.","PeriodicalId":93989,"journal":{"name":"Endocrine-related cancer","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142741786","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}

Clinically, interpatient body composition changes are heterogeneous, but the biological and clinical determinants of body composition toxicity are unknown. Herein, we test the hypothesis that inherited polymorphisms in steroidogenic genes are associated with differential changes in body composition after HT. Men with biochemically recurrent prostate cancer (BCR) who received 8 months of LHRH analog (LHRHa) +/- abiraterone acetate (AAP) were eligible if they had: i) CT imaging of L3 prior to and after treatment; and ii) nucleated cells collected. Cardiometabolic co-morbidities were retrospectively extracted. Body composition was measured using an AI-based segmentation tool. Germline DNA whole exome or genome sequencing was performed. In 162 men treated with 8 months of HT, median skeletal muscle mass (SMMi) loss was 6.6% and subcutaneous adipose gain was 12.3%. Men with type 2 diabetes had higher losses of SMMi after treatment (-11.1% vs -6.3%, P = 0.003). For the 150 men with germline NGS, SRD5A2 rs523349 genotype was associated with differential loss in skeletal muscle density after HT, (-1.3% vs -7.1%, P = 0.04). In addition, the HSD3B1 rs104703 genotype was associated with decreased baseline visceral adipose tissue (63.0 cm2/m2 vs 77.9, P = 0.05). In men with BCR, HT induced notable loss of skeletal muscle and increased subcutaneous adipose tissue.

Given their ability to reduce risk factors, albeit with varying efficacy, nutrition and fasting could help prevent cancer and other age-related disorders. Calorie restriction (CR), various forms of intermittent fasting (IF) or periodic fasting (PF), and fasting-mimicking diets (FMDs) have been shown to improve health span, increase lifespan, and prevent or postpone cancer in rodents. The effects of specific diets and fasting regimens on aging and cancer appear to be mediated in part by the reduction in the activity of the growth hormone (GH)/insulin-like-growth-factor-I (IGF-1) axis. Nevertheless, recent data indicate that the alternation of low and normal levels of these hormones and factors may be ideal for optimizing longevity and function. Here, we review the role of nutrition, CR, and fasting/FMD on cancer, focusing on the hypothesis that the modulation of GH, IGF-1, and insulin signaling partly mediates the effect of these dietary interventions on cancer prevention.","PeriodicalId":93989,"journal":{"name":"Endocrine-related cancer","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11771996/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142019949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
