Markus Hartl* and Rainer Schneider Center of Molecular Biosciences (CMBI), Institute of Biochemistry, University of Innsbruck, Innsbruck, Austria The neuronal proteins GAP43 (neuromodulin), MARCKS, and BASP1 are highly expressed in the growth cones of nerve cells where they are involved in signal transmission and cytoskeleton organization. Although their primary structures are unrelated, these signaling proteins share several structural properties like fatty acid modification, and the presence of cationic effector domains. GAP43, MARCKS, and BASP1 bind to cell membrane phospholipids, a process reversibly regulate...

In this study, we extended our previous joint gene analysis framework to joint gene set analysis framework. Base on the assumption that similar disease tends to share similar disease-related genes and pathways (Carson et al., 2017; Qin and Lu, 2018), we developed two joint gene set analysis frameworks aiming at improving identification power of enriched gene sets by borrowing different levels of information from other similar diseases. Compared with previous joint gene analysis framework, we unified DE gene/pathway statistic modeling through a two-component beta-uniform mixture model of p-values and combined the model with...

In this study, the immunohistochemistry results demonstrated that DEPDC1 was high-expressed in breast cancer tissues compared with the paired adjacent normal breast tissues, and its tendency at protein level was consistent with mRNA level from TCGA data. Moreover, DEPDC1 mRNA level revealed the strongest association with poor prognosis and development in breast cancer. In vitro assays showed that DEPDC1 overexpression resulted in significant promotion of proliferation by regulating cell cycle in MCF-7 cells, whilst an opposite effect was found in the MDA-MB-231 cells with DEPDC1 deletion. Notably, further investigation ind...

In conclusion, osmotic burst of inflated complement-damaged cells may occur, but these bursts are most likely a consequence of metabolic collapse of the cell rather than the cause of cell death. The Complement Cell Death Mediator: A Concerted Action of Toxic Moieties Membrane pores caused by complement were first visualized by electron microscopy on red blood cell membranes as large ring structures (22). Similar lesions were viewed on E. coli cell walls (23). Over the years, ample information on the fine ultrastructure of the MAC that can activate cell death has been gathered (24) and has been recently further examined (...

Conclusions: CAR T cell therapies have demonstrated the clinical benefits of harnessing our body's own defenses to combat tumor cells. Similar research is being conducted on lesser known modifications and gene-modified immune cells, which we highlight in this review. Introduction Chimeric antigen receptors and engineered T cell receptors (based on previously identified high affinity T cell receptors) function by redirecting T cells to a predefined tumor-specific (or tumor-associated) target. Most of these modifications use retroviral or lentiviral vectors to integrate the construct, and most of the receptors ...

Authors: Paschke L, Jopek K, Szyszka M, Tyczewska M, Malendowicz LK, Rucinski M Abstract Zinc finger protein 91 (ZFP91) gene has been recently acknowledged to possess oncogenic properties. To date, its expression has been examined only in a handful of human organs and cancer types. The aim of the present study was to characterize, for the first time, the ZFP91 expression pattern in a range of human tissues and cancer types. ZFP91 mRNA expression was examined using Cancer Survey cDNA sets. Utilized cDNA samples represented 15 human organs and 17 cancer types. ZFP91 mRNA expression was the highest in the testes and l...

Abstract Tubugi-1 is a small cytotoxic peptide with picomolar cytotoxicity. To improve its cancer cell targeting, it was conjugated using a universal, modular disulfide derivative. This allowed conjugation to a neuropeptide-Y (NPY)-inspired peptide [K4(C-βA-),F7,L17,P34]-hNPY, acting as NPY Y1 receptor (hY1R)-targeting peptide, to form a tubugi-1–SS–NPY disulfide-linked conjugate. The cytotoxic impacts of the novel tubugi-1–NPY peptide–toxin conjugate, as well as of free tubugi-1, and tubugi-1 bearing the thiol spacer (liberated from tubugi-1–NPY conjugate), and native tubulysin A as refe...

Primary prostatic stromal sarcoma is an extremely rare disease that predominantly occurs in adults, accounting for only 0.1% of all prostate cancers. Prostatic stromal sarcoma is quite aggressive and can spread to lung, liver, bone, and other organs. Metastasis is one of the most important predictors for prognosis. Here, we reported a case of a 17-year-old adolescent boy diagnosed with primary prostatic stromal sarcoma through prostate biopsy, and stage was confirmed by 18F-FDG PET/CT.
