Cancer study may accidentally help researchers create usable blood stem cells

(University of Colorado Anschutz Medical Campus) University of Colorado Cancer Center study shows that cancer-causing MLL gene may also push pluripotent stem cells to make hematopoietic stem cells, a strong step in the decades-long effort to make personalizable, durable blood stem cells.

In this study, we established a successive xenograft model to enrich Epstein-Barr virus-associated gastric carcinoma (EBVaGC) cancer stem cells (CSCs) through long-term treatment of EBVaGC cell line SNU719 with 5-Fluorouraci (5-Fu) in mice vivo passage. Simply, NOD/SCID mice injected in the subcutaneous with SNU719 were treated with 5-Fu weekly until xenografts reached 1.5 cm diameter and the mice were euthanizedand single-cell suspensions were obtainedby collagenasedigestion. Then the purified cells were passaged in 5-Fu-treated NOD/SCID mice as above. After four successive generations,we obtained theSNU-4th cells from th...

Conclusion: These results showed that CD133 expression can be regulated by methylation. Thus, the demethylation of the CD133 promoter may compromise the treatment of lung cancer by inactivating cancer stem cells and/or activating CGAs. PMID: 32090054 [PubMed]

Authors: Rutkowska A, Stoczyńska-Fidelus E, Janik K, Włodarczyk A, Rieske P Abstract Epidermal growth factor receptor variant III (EGFRvIII) seems to constitute the perfect therapeutic target for glioblastoma (GB), as it is specifically present on up to 28-30% of GB cells. In case of other tumor types, expression and possible role of this oncogene still remain controversial. In spite of EGFRvIII mechanism of action being crucial for the design of small active anticancer molecules and immunotherapies, i.e., CAR-T technology, it is yet to be precisely defined. EGFRvIII is known to be resistant to degradation, but i...

AbstractBreast cancer (BC) is the most common malignancy in women with a significant increasing incidence during the reproductive life. However, based on the newest anti-cancer molecular targeting drugs, successful treatments lead to the disease healing particularly in young patients, thus refreshing their motherhood programs. However, as effect of the BC treatment, a premature depletion of the ovarian follicle reserve occurs in more than one-third of patients resulting in permanent infertility. To prevent the cancer treatment-related infertility (CTRI), several options are today utilized. Besides the ovary suppression by ...

Pheochromocytoma (PCC) and paraganglioma (PGL) are rare neuroendocrine tumors associated with high cardiovascular morbidity and variable risk of malignancy. The current therapy of choice is surgical resection. Nevertheless, PCCs/PGLs are associated with a lifelong risk of tumor persistence or recurrence. A high rate of germline or somatic mutations in numerous genes has been found in these tumors. For some, the tumorigenic processes are initiated during embryogenesis. Such tumors carry gene mutations leading to pseudohypoxic phenotypes and show more immature characteristics than other chromaffin cell tumors; they are also ...

Conclusions: Our results provide a transcriptional rationale for the lack of significant therapeutic benefit from temozolomide in patients with recurrent glioblastoma. Our findings imply that the spectrum of potentially effective drugs is likely to differ between newly diagnosed and recurrent glioblastomas and underscore the merits of glioblastoma stem cells as prognostic models for identifying alternative drugs and predicting drug response in recurrent glioblastoma. With the majority of recurrent glioblastomas being inoperable, glioblastoma stem cell models provide the means of compensating for the limited availability of...
