70). Implementation of an initial GMAX activation program should be considered to facilitate neuromuscular adaptations that facilitate utilization of GMAX during hip strengthening exercises.A three-component reaction of phenylactylene, trifluoromethyl thianthrenium triflate (TT-CF3+OTf-) and sodium sulfinates under extremely mild conditions is developed, leading to various trifluoromethyl-substituted vinyl sulfones in moderate to good yields with excellent stereoselectivity. Additionally, elaboration of trifluoromethyl-substituted vinyl sulfone by palladium-catalyzed amination is performed. These trifluoromethyl-substituted vinyl sulfones are further evaluated for several assays against different tumor cells and the antitumor mechanism in cytotoxic autophagy induced by PI3K/Akt/mTOR signal is investigated.The SNCA gene encodes the presynaptic α-synuclein (aSyn) protein, and its mutations are associated with autosomal dominant Parkinson's disease (PD). We describe the generation of an induced pluripotent stem cell (iPSC) line of a patient carrying a pathogenic Ala53Thr missense mutation in the SNCA gene. Human dermal fibroblasts were reprogrammed using a non-integrating episomal method. The generated iPSC line (EURACi014-A; iPS-1.1) shows expression of pluripotency markers, the potential to differentiate into all three germ layers, and a stable karyotype. STAT3-IN-1 in vitro Hence, this line represents a valuable resource for the study and modeling of the processes directly controlled by aSyn.
Positron Emission Tomography is an important molecular imaging technique for detection and diagnoses of various disease states. This work aims to develop novel titanium-45 (t
= 3.08 h) PET tracers using Prostate Specific Membrane Antigen (PSMA) targeting vectors for imaging of prostate cancer as proof of concept for this relatively unexplored isotope.
Titanium-45 was produced on the University of Alabama at Birmingham (UAB) TR24 cyclotron using proton bombardments on natural scandium foils and separated using procedures described previously [1]. After purification, Titanium-45 was used to radiolabel two PSMA-targeting molecules; DFO-DUPA and LDFC-DUPA. Radiochemical yields were determined via radio-high purity liquid chromatography (radioHPLC). The radiolabeled compounds were tested both in vitro and in vivo using PSMA+ cell lines (LNCaP and 22Rv1) and PSMA- cell lines (PC3).
Titanium-45 was produced and purified in yields suitable for research studies. Radiochemical yields of up to 98 ± 1% were achieel PSMA targeting compounds with high radiochemical yields. These radiolabeled compounds remain intact in serum for at least two half-lives of titanium-45, showing that these compounds would be appropriate for implementation in the clinical setting. This study shows the feasibility of using titanium-45 as positron emitting radiometal for use in imaging PSMA+ prostate cancer, and illustrates that further research is in this area is warranted.
Familial adenomatous polyposis (FAP) is an autosomal dominant hereditary cancer syndrome characterized by hundreds to thousands of colorectal adenomatous polyps. Without treatment, progression to colorectal cancer is inevitable. Most pathogenic mutations in the APC gene were nonsense or frameshift mutations; however, some previous studies reported large deletions or duplications.
We reviewed the results of APC gene analyses from January 2010 to December 2020. We analyzed the entire coding sequence of the APC gene by Sanger sequencing to detect genetic abnormalities. Moreover, multiplex ligation-dependent probe amplification (MLPA) testing was performed starting in September 2017, and a multigene panel study that includes the APC gene was begun in July 2019.
In the 266 collected cases, pathogenic variants/likely pathogenic variants (PV/LPVs) in the APC gene were detected in 73 patients, and variants of uncertain significance were found in 13 patients. Among those variants, 14 variants were novel. We performed MLPA for 29 patients, and 7 of them (24.1%) were positive for a large duplication/deletion. Among the 73 cases in the multigene panel study, 17 cases (23.3%) of APC gene variation were detected.
We retrospectively analyzed the APC gene in Korean patients suspected to have FAP. Variants truncated by nonsense and frame shift mutations were common PV/LPVs. However, the detection rate in the MLPA study was higher than in previous studies of Caucasian populations. We suggest that MLPA should be performed for patients likely to have FAP but in whom no variant is detected by sequencing methods.

Mummified piglets are an important challenge affecting production efficiency in the pig industry. However, the value of metabolomics in unraveling the mechanisms of piglet mummification has not yet been established. This study aimed to investigate the serum and urine metabolomes of sows to identify biomarkers of piglet mummification. During gestation (35th, 56th, 77th, and 98th), serum and urine samples were collected from eight pigs from each group. To assess changes in metabolite classes in serum and urine from sows with a high incidence of mummified piglets and normal sows, a combination of liquid chromatography-mass spectrometry-based metabolomics profiling approach was used. The identified metabolites were involved in taurine and hypotaurine metabolism, glycine, serine and threonine metabolism, arginine and proline metabolism, and bile secretion. A total of six potential markers related to piglet mummification were screened, including hypotaurine, taurodeoxycholic acid, taurocholic acid, arginine, glutamic acid, and proline. These metabolites are expected to be novel biomarkers of piglet mummification, although their use requires further validation.Sertoli cells (SCs), the only somatic constituent of the testicular seminiferous epithelium, are vital to spermatogenesis. We previously found that vitamin C (ascorbic acid, AA) can reprogram the transcriptome, and promote the proliferation and reproductive function of pig immature SCs (iSCs). However, the global change of microRNAs (miRNA) expression and its effect on pig iSCs as induced by vitamin C treatment is still unknown. Here, we performed small RNA sequencing on pig iSCs after 250 μM AA2P (l-ascorbic acid 2-phosphate sesquimagnesium salt hydrate) treatment for 36h. Total number of detected miRNAs ranged from 326 to 335 known, and 400-570 novel miRNAs. Of the top ten highly expressed miRNAs, we found that 8 were common (miR-21-5p, let-7i-5p, miR-30a-5p, let-7f-5p, let-7g, miR-100, miR-10a-5p and miR-30d), which were predicted to target mRNAs involved in cell development and differentiation. We identified 78 differentially expressed (DE) miRNAs (|log2 (Fold Change)|≥1; Padj. less then 0.05), including 7 known and 71 novel miRNAs. We further selected 13 highly and stably expressed DE miRNAs (4 up-regulated miR-184, novel-miR-610, novel-miR-316 and novel-miR-1274; 9 down-regulated miR-222, miR-221-5p, miR-221-3p, miR-210, miR-146b, miR-146a-5p, novel-miR-182, novel-miR-1088 and novel-miR-1016), and performed integrated analysis on the miRNA-mRNA regulatory network. DE mRNAs negatively targeted by these 13 DE miRNAs were enriched in multiple GO and KEGG signaling pathways (e.g. pyruvate and steroid metabolic processes, developmental process in reproduction, response to oxidative stress, Glycolysis/Gluconeogenesis and HIF-1). We validated 8 DE miRNAs and their 12 DE mRNA targets, most of them showed expression patterns consistent with (mi)RNA-seq results. Taken together, our findings demonstrate that vitamin C could induce the global change of miRNAs, which possibly regulate cell proliferation, energy metabolism and male reproduction as induced by vitamin C treatment on pig iSCs.To identify potential new reagents and biomarkers for early lung cancer detection we combined the use of a novel preclinical isogenic model of human lung epithelial cells comparing non-malignant cells with those transformed to full malignancy using defined oncogenic changes and our on-bead two color (red and green stained cells) (OBTC) peptoid combinatorial screening methodology. The preclinical model used normal parent lung epithelial cells (HBEC3-KT, labeled with green dye) and isogenic fully malignant transformed derivatives (labeled with a red dye) via the sequential introduction of key genetic alterations of p53 knockdown, oncogenic KRAS and overexpression of cMYC (HBEC3p53, KRAS, cMYC). Using the unbiased OBTC screening approach, we tested 100,000 different peptoids and identified only one (named JM3A) that bound to the surface of the HBEC3p53, KRAS, cMYC cells (red cells) but not HBEC3-KT cells (green cells). Using the JM3A peptoid and proteomics, we identified the protein bound as vimentin using multiple validation approaches. These all confirmed the cell surface expression of vimentin (CSV) on transformed (HBEC3p53, KRAS, cMYC) but not on untransformed (HBEC3-KT) cells. JM3A coupled with fluorophores was able to detect and stain cell surface vimentin on very early stage lung cancers but not normal lung epithelial cells in a fashion comparable to that using anti-vimentin antibodies. We conclude using a combined isogenic preclinical model of lung cancer and two color screening of a large peptoid library, we have identified differential expression of cell surface vimentin (CSV) after malignant transformation of lung epithelial cells, and developed a new peptoid reagent (JM3A) for detection of CSV which works well in staining of early stage NSCLCs. This new, highly specific, easy to prepare, CSV detecting JM3A peptoid provides an important new reagent for identifying cancer cells in early stage tumors as well as a resource for detection and isolating of CSV expressing circulating tumor cells.Chagas disease (CD) is a centenarian neglected parasitosis caused by the protozoan Trypanosoma cruzi (T. cruzi). Despite the continuous efforts of many organizations and institutions, CD is still an important human health problem worldwide. A lack of a safe and affordable treatment has led drug discovery programmes to focus, for years, on the search for molecules enabling interference with enzymes that are essential for T. cruzi survival. In this work, the authors want to offer a brief overview of the different validated targets that are involved in diverse parasite pathways glycolysis, sterol synthesis, the de novo biosynthesis of pyrimidine nucleotides, the degradative processing of peptides and proteins, oxidative stress damage and purine salvage and nucleotide synthesis and metabolism. Their structural aspects, function, active sites, etc. were studied and considered with the aim of defining molecular bases in the search for new effective treatments for CD. This review also compiles, as much as possible, all the inhibitors reported to date against these T.
