El-GhettanyAbstractA novel bis-bidentate azo dye ligand, formed by the diazotized reaction of 1,4-diaminobenzene and 8-hydroxyquinoline in 1:2 M ratio resulted the formation of 5,5`-{(1E, 1E′)-1,4-phenylenebis(diazene-2,1-diyl)}bis(quinolin-8-ol) (H2L1) as primary ligand and its Cu(II), Ni(II), Co(II), Mn(II), Cr(III), UO2(II) and Cd(II) complexes. Incorporating of 8-hydroxyquinoline (HL2) as co-ligand with the formed mixed-ligand complexes were synthe...

Authors: Qiu Y, Yang S, Pan T, Yu L, Liu J, Zhu Y, Wang H Abstract Prostate cancer is a common malignant tumor in elderly men. As a novel metabolic-reprogramming molecule, the role of ankyrin repeat domain 22 (ANKRD22) in the tumorigenesis and progression of prostate cancer remains unknown. In the present study, mouse monoclonal antibodies against human ANKRD22 were prepared using recombinant ANKRD22 from prokaryotic expression and validated. Subsequently, these antibodies were used to evaluate ANKRD22 levels via immunohistochemical staining in prostate cancer tissues. Finally, the association between ANKRD22 level...

lncRNA MIR4435-2HG promotes cancer cell migration and invasion in prostate carcinoma by upregulating TGF-β1. Oncol Lett. 2019 Oct;18(4):4016-4021 Authors: Zhang H, Meng H, Huang X, Tong W, Liang X, Li J, Zhang C, Chen M Abstract The long noncoding (lnc) RNA MIR4435-2HG is known to promote lung cancer; however, its role in prostate carcinoma (PCa) remains unknown. The aim of the current study was therefore to investigate the role of MIR4435-2HG in PCa by detecting differential gene expression using quantitative PCR and ELISA kits. Furthermore, overexpression experiments were performed to analyze ge...

Authors: Shi Z, Guo F, Jia D, Huang J, Chen J, Sun M, Qi F, Liang C Abstract A previous study reported the decreased expression of long non-coding RNA mortal obligate RNA transcript (lncRNA MORT) in 16 types of cancer, while the functionality of lncRNA MORT in cancer biology remains unknown. Therefore, the present study was conducted to characterize the functionality of lncRNA MORT in prostate carcinoma, a common cancer type worldwide. lncRNA MORT expression level was downregulated in tumor tissues compared with that in the adjacent healthy tissues of patients with prostate carcinoma. Expression of lncRNA MORT in t...

STEPHEN FRY is one of the nation ’s fondest figures. The multi-talented actor shocked his fanbase last year when he took to Twitter to reveal he had been diagnosed with prostate cancer. The actor, who has now made a full recovery, recounted the events in minute detail to raise awareness.

Publication date: Available online 12 September 2019Source: SteroidsAuthor(s): Debbie O'Reilly, Patricia Johnson, Paul.J BuchananAbstractAndrogen deprivation therapy (ADT) is the main treatment to prolong survival in advance stage prostate cancer (PCa) but associated resistance leads to the development of terminal castrate resistant PCa (CRPC). Current research demonstrates a critical role of prostate cancer stem cells (PCSC) in the development of treatment resistance and subsequent disease progression. Despite uncertainty surrounding the origin of these cells, studies clearly show they are associated with poorer outcomes ...

Every year, tens thousands of men in the United States are diagnosed with low-risk prostate cancer. Most are told that they don ’t need treatment other than “active surveillance” to monitor their slow-growing tumors. Now, UCLA physicians have shown that the best way to proceed with this is by starting out with an MRI-guided prostate biopsy.In the past, doctors relied on ultrasound to guide a biopsy needle into the prostate. However, ultrasound doesn ’t allow the visualization of prostate tumors, so a biopsy may have missed a tumor. Over the past decade, it’s become possible to instead perform ...

Ulrika Rosenström Simultaneous targeting of the prostate-specific membrane antigen (PSMA) and gastrin-releasing peptide receptor (GRPR) could improve the diagnostic accuracy in prostate cancer (PCa). The aim of this study was to develop a PSMA/GRPR-targeting bispecific heterodimer for SPECT and positron emission tomography (PET) diagnostic imaging of PCa. The heterodimer NOTA-DUPA-RM26 was produced by manual solid-phase peptide synthesis. NOTA-DUPA-RM26 was labeled with 111In and 68Ga, with yields >98%, and demonstrated a high stability and binding specificity to PSMA and GRPR. IC50 values for natIn-NOTA-DU...

Alejandro S. Godoy Tissue homeostasis is the result of a complex intercellular network controlling the behavior of every cell for the survival of the whole organism. In mammalian tissues, cells do communicate via diverse long- and short-range communication mechanisms. While long-range communication involves hormones through blood circulation and neural transmission, short-range communication mechanisms include either paracrine diffusible factors or direct interactions (e.g., gap junctions, intercellular bridges and tunneling nanotubes) or a mixture of both (e.g., exosomes). Tumor growth represents an alteration of tis...
