Targeting cancer stem cells improves treatment effectiveness and prevents metastasis

This study shows that for the first time, targeting the proliferating tumor mass and dormant cancer stem cells with combination therapy effectively inhibited tumor growth and prevented metastasis compared to monotherapy in mice,” said Wang, who is a member of the UCLA Jonsson Comprehensive Canc er Center and of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA. “Our discovery could be applied to other solid tumors such as breast and colon cancer, which also frequently metastasizes to lymph nodes or distant organs.”“With this new and exciting study, Dr. Wang and his team have provided the building blocks for understanding the cellular and genetic mechanisms behind squamous cell carcinoma,” said Dr. Paul Krebsbach, dean of the UCLA School of Dentistry. “The work has important translational values. Small m olecule inhibitors for cancer stem cells in this study are available or being utilized in clinical trials for other diseases. It will be interesting to conduct a clinical trial to test these inhibitors for head and neck squamous cell carcinoma.”Additional authors of the study include Demeng Cheng, first author and postdoctoral scholar in Wang ’s lab; Mansi Wu, Yang Li, Dr. Insoon Chang, Yuan Quan, Mari Salvo, Peng Deng, Dr. Bo Yu, Yongxin Yu, Jiaqiang Dong, John M. Szymanski, Sivakumar Ramadoss and Jiong Li who are all from the laboratory of molecular signaling in the division of oral biology...

CONCLUSION: ELF3 showed selective expression in low-grade cell lines and tumor tissues. Overexpression of ELF3 in mesenchymal cell line UMUC3 resulted in reduced invasion and decreased expression of mesenchymal markers. We observe association of low ELF3 expression with increased risk and overall poor survival using publicly available data. ELF3-modulated reversal of EMT might be a useful strategy in the treatment of bladder cancer. PMID: 31104013 [PubMed - as supplied by publisher]

In this study, we aimed to explore the expressing pattern, clinical significance and potential function of a newly identified circRNA, hsa_circ_001569, in BC. RT-PCR was performed to detect the expression of hsa_circ_001569 in both BC tissues and cell lines. The associations between hsa_circ_001569 expression and clinicopathological features and prognosis in BC patients were statistically analyzed. Next, we investigated the effects of hsa_circ_001569 on the proliferation, apoptosis, migration and invasion in BC cells lines. The effects of abnormal hsa_circ_001569 expression on EMT pathway and PI3K/AKT pathway were determin...

CONCLUSION: To our knowledge this is the first study comparing the levels of protein and mRNA in the serum material of HGF, c-MET, EGF and EGFR parameters in lung cancer patients' blood samples. Further prospective studies with more participants for better understanding of mechanism and effect for HGF and c-MET inhibitors in lung cancer will help us to identify of these biomarkers role for guiding us to sellect individualized itargeted therapies.

Authors: Wu Z, Huang W, Chen Y, Chen B, Liu R, Bai P, Xing J Abstract LINC01638 lncRNA is known as an oncogenic lncRNA in triple negative breast cancer. However, the role of LINC01638 lncRNA in other diseases is unknown. In the present study we observed that plasma levels of LINC01638 lncRNA and Notch1 were upregulated in prostate carcinoma patients comparing with healthy controls. LINC01638 lncRNA and Notch1 were positively correlated in prostate carcinoma patients but not in healthy controls. Upregulation of LINC01638 lncRNA distinguished prostate carcinoma patients from healthy controls. LINC01638 lncRNA overexp...

CONCLUSIONS: BCL2L12 protein expression could be used as a favorable prognostic tissue biomarker in patients with primary advanced-stage LSCC. On the contrary, BCL2 and BAX did not correlate with prognosis in patients with primary LSCC. PMID: 31104007 [PubMed - as supplied by publisher]

Immunosenescence is the name give to the age-related decline in effectiveness of the immune system. Some authors consider this to be distinct from inflammaging, the growth in chronic inflammation due to overactivation of the immune system in response to molecular damage and the presence of senescent cells, while others consider that chronic inflammation to be an aspect of immunosenescence. In today's open access paper, researchers review immunosenescence from the perspective of the adaptive immune system, here meaning detrimental changes in T cell populations. The contributing causes of these changes are given as (a) the a...
