Knockdown of ubiquitin ‑specific protease 51 attenuates cisplatin resistance in lung cancer through ubiquitination of zinc‑finger E‑box binding homeobox 1.

Knockdown of ubiquitin‑specific protease 51 attenuates cisplatin resistance in lung cancer through ubiquitination of zinc‑finger E‑box binding homeobox 1. Mol Med Rep. 2020 May 27;: Authors: Zhou F, Du C, Xu D, Lu J, Zhou L, Wu C, Wu B, Huang J Abstract Lung cancer is a devastating cancer with high morbidity and mortality. Ubiquitin‑specific protease (USP) is a type of deubiquitinating enzyme (DUB) that has been implicated in numerous cancers, including colorectal, myeloma and breast. In the present study, the expression of USP51 was determined in the lung cancer cell line A549 and cisplatin (also known as DDP)‑resistant lung cancer strain A549/DDP. The expression of zinc‑finger E‑box binding homeobox 1 (ZEB1), a transcriptional repressor, was also examined. The effects of USP51 knockdown or overexpression on proliferation and apoptosis, as well as the impact of ZEB1 overexpression and USP51 interference on apoptosis and ubiquitination were then assessed. Notably, increased expression of USP51 and ZEB1 in A549/DDP cells was observed, and treatment with DDP significantly inhibited proliferation in A549/DDP cells. In addition, knockdown of USP51 in A549/DDP cells significantly induced apoptosis, decreased ZEB1 expression and increased cleaved poly ADP‑ribose polymerase 1 (PARP1) and cleaved caspase‑3 levels. Consistently, USP51 overexpression in A549 cells displayed the opposite effects and potently attenuated DDP‑induced apoptosis....

ConclusionPatients with cancer who need treatment can be treated by taking some measures. These measures include observing individual and collective protection principles in patients and health-care personnel, increasing patients ’ awareness particularly about self-care behavior, performing a COVID-19 test, and taking a chest X-ray, before the treatment starts

Abstract The critical roles of long non-coding RNAs (lncRNAs) in the regulation of diverse biological functions has potentiated them as cancer biomarkers. Among these transcripts is the prostate cancer associated transcript 1 (PCAT1) which has been initially shown to exert oncogenic roles in prostate cancer. Further studies revealed its similar roles in various kinds of human malignancies including both solid tumors and hematological malignancies. Animal studies have shown that down-regulation of this lncRNA can attenuate tumor growth in a wide array of cancers including prostate cancer, colorectal cancer, squamou...

In conclusion, DNAM-1 or NKG2D over-expression elicited a dynamic increase in NK cell degranulation against all sarcoma explants and cancer cell lines tested, including those that failed to induce a notable response in WT NK-92 cells. These results support the broad therapeutic potential of DNAM-1+ or NKG2D+ GM NK-92 cells and GM human NK cells for the treatment of sarcomas and other malignancies.

ConclusionsOur study revealed that that GRP94 expression in lung AD favors tumor progression and predicts poor prognosis. The oncogenic role of GRP94 may involve inducing Treg infiltration by promoting the TGF ‐β signaling pathway.Key points GRP94 protein levels were elevated in lung AD tissues compared to normal lung tissues. The high expression ofGRP94 in lung AD favors tumor progression and predicts poor prognosis. The oncogenic role of the molecule GRP94 may involve the stimulation of Treg infiltrationvia promotion of the TGF ‐β signaling pathway.

nni Monteleone Cross-talk between cancer cells and the immune cells occurring in the tumor microenvironment is crucial in promoting signals that foster tumor growth and metastasis. Both cancer cells and immune cells secrete various interleukins (IL), which, either directly or indirectly, stimulate cancer-cell proliferation, survival, and diffusion, as well as contribute to sculpt the immune microenvironment, thereby amplifying tumorigenic stimuli. IL-34, a cytokine produced by a wide range of cells, has been initially involved in the control of differentiation, proliferation, and survival of myeloid cells. More recent ...

CONCLUSIONS: 1. Patients with long-bone cancer metastases with pathological fractures or risk of fracture require surgical management. 2. Nailing or modular prosthesis produced the best functional result at 6 weeks post-operatively. 3. All methods of surgical treatment reduced pain and improved the quality of life.

In this study, we reviewed major human studies on the health risks of radiation exposure and showed that sex-related factors may potentially influence the long-term response to radiation exposure. Available data suggest that long-term radiosensitivity in women is higher than that in men who receive a comparable dose of radiation. The report on the biological effects of ionizing radiation (BEIR VII) published in 2006 by the National Academy of Sciences, United States emphasized that women may be at significantly greater risk of suffering and dying from radiation-induced cancer than men exposed to the same dose of radiation....
