(Press-News.org) Background and objectives
circPVT1 has emerged as a key regulator in disease progression and clinical outcomes. However, its prognostic relevance and association with clinicopathological parameters in solid malignancies remain to be fully elucidated. To address this, we conducted a meta-analysis to elucidate the clinical significance of circPVT1 in solid tumors.
Methods
A comprehensive literature search was conducted across multiple databases, including PubMed, Web of Science, Embase, the Cochrane Library, and CNKI, with a cutoff date of December 31, 2024. Statistical analyses were conducted using STATA 12.0 to calculate pooled hazard ratios (HRs) and odds ratios (ORs) with 95% confidence intervals (CIs), assessing the impact of circPVT1 expression on overall survival (OS) and its association with clinicopathological characteristics.
Results
This analysis included 27 clinical studies encompassing a total of 2,219 patients. Elevated circPVT1 expression was significantly associated with poorer OS in patients with solid tumors (HR = 1.68, 95% CI: 1.39–2.02, P < 0.001). This association was particularly notable in lung cancer (HR = 2.08, 95% CI: 1.51–2.88, P < 0.001) and osteosarcoma (HR = 1.65, 95% CI: 1.38–1.97, P < 0.001), with similar trends observed in hepatocellular carcinoma, colorectal cancer, and papillary thyroid carcinoma. Furthermore, the increased circPVT1 level was correlated with larger tumor size (OR = 1.36, 95% CI: 1.11–1.67, P = 0.004), lymph node metastasis (OR = 1.56, 95% CI: 1.22–2.00, P < 0.001), distant metastasis (OR = 1.80, 95% CI: 1.10–2.92, P = 0.017), and advanced tumor-node-metastasis stage (OR = 1.84, 95% CI: 1.50–2.25, P < 0.001).
Conclusions
Our meta-analysis indicated that elevated circPVT1 expression levels are closely linked to unfavorable OS in tumor patients. circPVT1 has the potential to act as both a prognostic indicator and a molecular target for solid tumor therapy. Future research should focus on validating these findings through large-scale, multicenter prospective studies to further establish the clinical utility of circPVT1 in cancer management.

The study was recently published in the Exploratory Research and Hypothesis in Medicine.
Exploratory Research and Hypothesis in Medicine (ERHM) publishes original exploratory research articles and state-of-the-art reviews that focus on novel findings and the most recent scientific advances that support new hypotheses in medicine. The journal accepts a wide range of topics, including innovative diagnostic and therapeutic modalities as well as insightful theories related to the practice of medicine. The exploratory research published in ERHM does not necessarily need to be comprehensive and conclusive, but the study design must be solid, the methodologies must be reliable, the results must be true, and the hypothesis must be rational and justifiable with evidence.

VINCI. Italy — For over five centuries, Leonardo Da Vinci has been celebrated as a visionary artist, scientist, and inventor, known for his extraordinary talent and groundbreaking experiments. Today, an international collaboration known as the Leonardo DNA Project is closer than ever to uncovering the biological secrets of the greatest genius of the Renaissance.
In their new book “Genìa Da Vinci. Genealogy and Genetics for Leonardo’s DNA,” published by Angelo Pontecorboli Editore, experts Alessandro Vezzosi and Agnese Sabato of the Leonardo Da Vinci Heritage ...
Wednesday, May 21, 2025, CLEVELAND: Cleveland Clinic has been awarded a $5 million grant from the Cystic Fibrosis Foundation to continue its role as the Biorepository Coordinating Center for the Cystic Fibrosis Lung Transplant Consortium until 2030. The coordinating center provides the infrastructure to support research to improve understanding of the factors that affect lung transplant outcomes.
The initiative, which includes 15 participating institutions in North America, is led by Maryam Valapour, M.D., M.P.P., director of Lung Transplant Outcomes at Cleveland Clinic, and Suzy Comhair, Ph.D., scientific director of Cleveland ...
NEW ORLEANS, May 21, 2025 – When pollinators visit flowers, they produce a variety of characteristic sounds, from wing flapping during hovering, to landing and takeoff. However, these sounds are extremely small compared to other vibrations and acoustics of insect life, causing researchers to overlook these insects’ acoustic signals often related to wing and body buzzing.

An international study led by the University of Colorado Cancer Center has uncovered why a widely used treatment for acute myeloid leukemia (AML) doesn’t work for everyone. The findings could help doctors better match patients with the therapies most likely to work for them.
The study was published today in Blood Cancer Discovery.
Researchers analyzed data from 678 AML patients, the largest group studied to date for this treatment and found that both gene mutations and the maturity of leukemia cells affect ...
PULLMAN, Wash. – The way people express emotions while helping others can influence whether their assistance is welcomed, resented, or reciprocated, according to new research from Washington State University’s Carson College of Business.
The study, led by Stephen Lee, assistant professor of management, found that helpers who express emotions like gratitude and sympathy are more likely to be seen as having genuine motives and are more likely to foster trust and future collaboration. Conversely, when helpers display pride or contempt, their motives are often questioned, weakening relationships and reducing the likelihood of reciprocation.

Herndon, VA, May 21, 2025 -- Hurricane winds are a major contributor to storm-related losses for people living in the southeastern coastal states. As the global temperature continues to rise, scientists predict that hurricanes will get more destructive -- packing higher winds and torrential rainfall. A new study, published in the journal Risk Analysis, projects that wind losses for homeowners in the Southeastern coastal states could be 76 percent higher by the year 2060 and 102 percent higher by 2100.
