Kidney

Kidneys are vital organs that play a crucial role in the human body.
They are responsible for filtering waste and excess fluids from the blood, maintaining fluid balance, and regulating blood pressure.
Kidneys also produce hormones that help control red blood cell production, calcium absorption, and blood pressure.
Proper kidney function is essential for overall health and well-being.
Researchers in the field of kidney studies utilize advanced tools like PubCompare.ai to optimize their research by identifying the most effective treatments and products through accurate, reproducilbe studies and AI-driven comparisons.

Genome-wide expression was measured in liver and kidney using RNA-seq on the Illumina GA I and hybridization of the same samples to Affymetrix HG-U133 Plus 2.0 arrays. The sample preparation and data analysis was designed to maximize the similarity between the microarray and RNA-seq experiments (see Marioni et al. [21 (link)]). Differential expression between kidney and liver was determined using an empirical Bayes modified t-statistic on the microarray platform and P-values for DE were downloaded from their website. For the RNA-seq experiment, the data were normalized using TMM normalization [27 ] and a negative binomial exact test was used to determine DE [16 (link)]. To test the GOseq method, we used the genes called DE from the microarray experiment to calculate the significance of over-representation of each GO category using the standard GO analysis methods. We also calculated P-values for each GO category being over-represented among genes that were DE in the RNA-seq data, using both the GOseq and hypergeometric methods. GOseq's ability to outperform the hypergeometric method, as measured by its ability to reproduce the results of the microarray GO analysis, was quantified by calculating a P-value for the difference in the two methods being due to chance. To do this, a NULL was chosen under which both methods were equally likely to correctly recover each microarray GO category, with this likelihood given by a binomial distribution.

Nuclear RNA was prepared from HEK293T (kidney) cells. Briefly, cells were lysed on ice for 5 min in 10 mM Tris-HCl pH 7.5, 10 mM NaCl, 0.2 mM EDTA, 0.05% NP-40, and nuclei were spun at 2,500g for 3 min and then resuspended in QIAzol for RNA isolation using the miRNeasy kit according to the manufacturer’s instructions (Qiagen). The RNA-seq library was created using the Illumina TruSeq RNA Sample Preparation Kit v2 with the standard protocol, and sequenced on one lane of the HiSeq 2000 platform (100 bp, paired-end). Data are available at NCBI as accession number SRP041943. The database of annotated protein coding and noncoding genes (41,409 genes and 171,904 transcripts in total) was produced by merging all annotated genes from the RefSeq database29 (link), the UCSC Browser24 (link) and the Ensembl database30 (link).

PhenoScanner consists of a Perl interface (with R command line tool) that connects to a MySQL database. To develop the initial database, we collated 137 genotype–phenotype association datasets, including results for anthropometric traits, blood pressure, lipids, cardiometabolic diseases, renal function measures, glycemic traits, inflammatory diseases, psychiatric diseases and smoking phenotypes (Supplementary Table). We also included the NHGRI-EBI GWAS catalog, NHLBI GRASP (Leslie et al., 2014 (link)) and dbGaP catalogues of associations. To ensure consistent formatting, we aligned alleles to the plus strand, added or updated chromosome positions to build 37 using dbSNP (release 138) (Sherry et al., 2001 (link)) and liftOver (https://genome.ucsc.edu/cgi-bin/hgLiftOver), and updated old rsIDs to dbSNP release 141 (Supplementary Data). Linkage disequilibrium (LD) measures between neighbouring variants in the autosomal chromosomes were calculated using the phased haplotypes from European samples in 1000 Genomes phase 3 (N = 503) (1000 Genomes Project Consortium et al., 2012 (link)). Variants with minor allele frequencies <0.5% were removed along with multiallelic variants and large indels ( 5 bases). For each remaining variant, we calculated D and r2 for variants within 500 kb in either direction, and kept LD statistics for pairs of variants with r20.6 . LD statistics based on the CEU population from Hapmap 2 release 24 (Frazer et al., 2007 (link)) are also available (Supplementary Data).
The user may enter either one variant into the text box on the website or upload up to 50 variants in a text file. The Perl interface annotates the variant alleles using dbSNP, identifies proxies of the specified variants (if requested) in the database according to a user-specified pairwise r2 threshold, and queries the catalogue of genotype–phenotype associations for the specified variants and their proxies. Association results are collated and presented with respect to the same effect and non-effect alleles for each variant. The associations with proxies are aligned according to the effect and non-effect alleles of the corresponding primary variant of interest for added ease of interpretation. The output is a file of associations, which is made available to download. There is also a P value filter option that only retains results with study-specific P values less than the selected threshold.

Double-stranded cDNA of eight human tissues (brain, heart, kidney, testis, liver, spleen, lung, and skeletal muscle) were generated with the Marathon cDNA amplification kit (Clontech). The cDNA concentration was normalized by quantitative PCR against AGPAT1 and EEF1A1 genes. The PCRs were performed in 386-well plates in a total volume of 12.5 μLl. One microliter of normalized cDNA was mixed with JumpStart REDTaq ReadyMix (Sigma) and primers (4 μM) with a Freedom evo robot (TECAN). The 10 first cycles of amplification were performed with a touchdown annealing temperature decreasing 1°C per cycle from 65°C to 55°C; annealing temperature of the next 30 cycles was carried out at 55°C. For each tissue, 2 μL of each RT-PCR reaction were pooled together and purified with the QIAquick PCR purification Kit (Qiagen) according to the manufacturer's recommendations. This purified DNA was directly used to generate a sequencing library with the “Genomic DNA sample prep kit” (Illumina) according to the manufacturer's recommendations with the exclusion of the fragmentation step. This library was subsequently sequenced on an Illumina Genome Analyzer 2 platform.

Example 19

Atypical hemolytic uremic syndrome (aHUS) is characterized by hemolytic anemia, thrombocytopenia, and renal failure caused by platelet thrombi in the microcirculation of the kidney and other organs. aHUS is associated with defective complement regulation and can be either sporadic or familial. aHUS is associated with mutations in genes coding for complement activation, including complement factor H, membrane cofactor B and factor I, and well as complement factor H-related 1 (CFHR1) and complement factor H-related 3 (CFHR3). Zipfel, P. F., et al., PloS Genetics 3(3):e41 (2007).

The effect of the exemplary fusion protein construct of this disclosure to treat aHUS is determined by obtaining and lysing red blood cells from aHUS patients treated with the exemplary fusion protein construct. It is observed that treatment with the exemplary fusion protein construct is effective in blocking lysis of red blood cells in the patients suffering from aHUS, compared to treatment with a sham control.

Example 7

Five groups including tucaresol, tucaresol plus PD-1 or PD-L1 antibody, tucaresol plus CTLA-4 antibody, CTLA-4 antibody plus PD-1 or PD-L1 antibody, and tucaresol plus plinabulin are tested to determine their effect in an animal xenograft model.

The combined treatment with tucaresol and the checkpoint inhibitor(s) is tested in comparison with the treatment with tucaresol alone, the treatment with checkpoint inhibitor alone, or combination of checkpoint inhibitors. The tests are performed using seven to ten-week old athymic (nu/nu) mice that were injected subcutaneously with human tumor cell lines (of either solid or liquid tumor origin, for example of breast, lung, colon, brain, liver, leukemia, myeloma, lymphoma, sarcoma, pancreatic or renal origin). Six to ten testing groups are prepared, and each group includes 10 mice.

Each treatment starts at tumor size between 40-150 mm3 and continues until Day 24-56, when the animals are necropsied. To determine the efficacy of each treatment, the following data are collected: mortality; the body weight of the mice assessed twice weekly both prior to treatments; the rate of tumor growth as determined by the tumor size measurement (twice every week); the tumor growth index; overall survival rate; the tumor weight at necropsy; and the time required to increase tumor size 10 fold.

Example 6

The AST cytotoxicity was evaluated and compared with that of inorganic As(III) using five different types of human cell lines from major organs/tissues: HEK293, immortalized embryonic kidney cells; THP-1, monocytes derived from an acute monocytic leukemia patient; macrophage, macrophage-like cells differentiated from THP-1; HepG2, immortalized cells isolated from a hepatocellular carcinoma; and Caco-2, immortalized cell line derived from a colorectal adenocarcinoma patient (FIG. 5). The results show that AST has much lower cytotoxicity in human cells than As(III). The LC50 values of AST on all the tested cell lines except Caco2 were greater than 250 μM. Caco-2 was relatively more sensitive to AST with a lower LC50 value (150-200 μM). In contrast, the LC50 values of As(III) on all the tested cell lines except macrophage were lower than 25 μM, while that of macrophage was higher (100 μM), suggesting that AST is >10 times less cytotoxic than As(III). AST at 100 μM completely inhibits PfGS-I activity (FIG. 2C), P. falciparum proliferation in blood (FIG. 3) and transmission to mosquitoes (FIG. 4A), but had little effect on most of the tested human cell lines (FIG. 5). Thus, AST is effective against the malaria parasite with limited effect on human cells.

Exemplary IL-17RA human mAbs were tested in a cynomolgus bioassay utilizing the cynomolgus-derived kidney epithelial cell line JTC-12 stimulated with cynomolgus IL-17A. FIG. 12 shows IL-17RA mAbs having the heavy and light chain sequences (AMH22/AML22), (AMH19/AML19), (AMH18/AML18) and (AMH14/AML14) in the inhibition of cynomolgus IL-17A-induced IL-6 production from JTC-12 cells. The (----) line depicts the positive control value of cynomolgus IL-17 in combination with TNF-alpha. The (-.-.-) line depicts the positive control value of cynomolgus TNF-alpha. The (....) line depicts the media control value. JTC-12 cells were preincubated for 30 mins with anti-IL-17RA mAbs and then stimulated overnight with cynomolgus IL-17A (5 ng/ml) and human TNF-alpha (5 ng/ml). FIG. 12 shows that each antibody was able to inhibit cynomolgous IL-17A from binding IL-17RA and inhibit IL-17RA activation, as determined by IL-6 production from JTC-12 cells. The IL-17RA antibody (AMH14/AML14) was able to antagonize cynomolgous IL-17A-induced IL-6 production from JTC-12 cells with an IC50 of approximately 1.2 nM.
