Stem Cell Vaccine Carries Potential as Mesothelioma Treatment

Researchers at the Stanford University School of Medicine believe a patient-specific stem cell vaccine could become part of mesothelioma treatment — and possibly prevention — in the future. The belief stems from their recent study that demonstrated a consistent immunologic response with genetically-altered stem cells in laboratory mice carrying particular cancer cells. “This could potentially play a role for a large group of — if not all — cancers,” Dr. Joseph Wu, director of the Stanford Cardiovascular Institute, told Asbestos.com. “We envision it potentially being used as a vaccine or adjuvant treatment for mesothelioma.” The study involved induced pluripotent stem cells (IPS), which are cells taken from the blood or skin and genetically reprogramed. This allows the cells to attack or prevent cancerous tumors when mixed with a generic immune-stimulating agent. Vaccine Shows Anti-Tumor Response The study tested mice infected separately with breast cancer, melanoma and mesothelioma cells. The anti-tumor response rate was similar in all three types of cancer. “This is significant for future cancer therapies, that we now have a surrogate cell that can provide the immune system with a large amount of cancer-related antigens,” Wu said. “Based on preliminary studies, the effectiveness of our vaccine is not limited to one cancer.” IPS cells typically are used in regenerative medicine, often to repair damage fro...

Authors: Gueudry J, Majo F, Delcampe A, Muraine M Abstract The corneal limbus is a privileged region on the border between two quite different microenvironments, where corneal epithelial stem cells, numerous melanocytes, and antigen-presenting cells are all concentrated within a richly vascularized and innervated stroma. This situation within the ocular surface confers on it the key functions of barrier, epithelial renewal and defense of the cornea. As an immunological crossroads and since the corneoscleral limbus is directly exposed to external insults such as caustic agents, ultraviolet radiation, microbial agent...

Abstract Cystoscopy and histology are the gold standards for detection of bladder cancer. However, these methods are highly subjective, expensive, and invasive. We have developed a non-invasive method for the diagnosis of bladder cancer by detecting telomerase activity in human urine. Telomerase substrate (TS) primer is elongated with repeating sequences of (TTAGGG)n in the presence of telomerase. The elongated primer can trigger hybridization chain reaction between two hairpins H1 and H2, result in the aggregation of AuNPs due to the hybridization between the tail sequence on H1 (or H2) and DNA-AuNPs probe, and a...

This study aimed to explore whether a correlation exists between the incidence and mortality of cancers and normalized internet search volumes on the big data platform, Baidu. We also assessed whether the distribution of people who searched for specific types of cancer differed by gender. Finally, we determined whether there were regional disparities among people who searched the Web for cancer-related information. Methods: Standard Boolean operators were used to choose search terms for each type of cancer. Spearman’s correlation analysis was used to explore correlations among monthly search index values for each can...

Cardiac tumors have generally been considered to be rare. They are often found incidentally as they tend to remain clinically silent, but they can sometimes present with symptoms secondary to obstruction, embolization, or invasion of the myocardium. Most cardiac tumors are secondary tumors from metastases, with primary cardiac tumors constituting approximately 15% of all cardiac tumors1. Although melanoma and pleural mesothelioma often have cardiac involvement, the most common cancers to be identified in cardiac metastases are lung cancer (36-39%), breast cancer (10-12%), and hematologic cancers (10-21%)2.

Conclusion: PTX3 could be a promising biomarker to differentiate PPE from other causes of pleural effusions. In PPE, an increased level of pleural fluid PTX3 level without a significant increase in serum PTX3 level may reflect a more intense local inflammation than those occur in MPE or TPE.

Conclusions • Physicians should have no hesitation prescribing natural progesterone. The evidence is clear that progesterone does not cause breast cancer. Indeed, progesterone is protective and preventative of breast cancer. PMID: 29055286 [PubMed - as supplied by publisher]
