Article Title: Impact of WIN site inhibitor on the WDR5 interactome

doi: 10.1016/j.celrep.2020.108636

Figure Lengend Snippet: (A) Endogenous PDPK1 was recovered from lysates of the indicated cell lines and probed for co-precipitating WDR5 by IB. Inputs for PDPK1 are 10%–20%. Inputs for WDR5 are 1%–5%. n = 3 biological replicates. (B) Proximity ligation assay with FLAG and WDR5 antibodies in U2OS cells stably expressing FLAG-tagged PDPK1. Cells were treated overnight (30 μM C6/C6nc) before analysis; scale bar, 20 μm. n = 3 biological replicates. (C) HEK293 cells were treated overnight with 30 μM C6 or 5 μM GSK470, lysates prepared, and a PDPK1 IP performed. IB was then performed for the indicated proteins. Inputs are 5% for PDPK1 and 1% for all others. n = 3 biological replicates. (D) HEK293 cells were fractionated into cytosolic (S2), soluble nuclear (S3), and chromatin-associated (P3) fractions. Equal amounts of each fraction were analyzed by IB with the antibodies against the indicated proteins. H3 (nuclear) and α-tubulin (cytosolic) are controls for fractionation. n = 3 biological replicates. (E) Cytosolic and nuclear lysates from HEK293 cells were subject to IP with PDPK1 antibody or an IgG control and immunoblotted with antibodies against the indicated proteins. A short and long exposure of the WDR5 IB are shown. n = 3 biological replicates. (F) PDPK1 possesses two WIN-like motifs centered on R3 and R238. (G) FLAG-tagged PDPK1 (WT and the R3A and R238A mutants) were transiently expressed in HEK293 cells; lysates were prepared and subject to IP with anti-FLAG beads. Immune complexes were probed for PDPK1 or endogenous WDR5 by IB. n = 3 biological replicates. (H) FLAG-tagged PDPK1 (WT and the R3A) was transiently expressed in HEK293 cells, recovered by FLAG-IP, resolved by SDS-PAGE, and transferred to polyvinylidene fluoride (PVDF) membrane. Membranes were then incubated with recombinant WDR5 followed by anti-WDR5 antibody. n = 3 biological replicates. (I) In vitro -transcribed and -translated PDPK1-FLAG variants were incubated with recombinant 6xHis-SUMO-WDR5 proteins, recovered with Ni-NTA agarose, and analyzed by IB. n = 2 biological replicates. PH, pleckstrin homology domain. See also .

Article Title: Generation and characterization of human induced pluripotent stem cells from neuropathologically confirmed multiple system atrophy patient-derived fibroblasts

doi: 10.3389/fimmu.2026.1641981

Figure Lengend Snippet: Assessment of the cell line identity and the genomic integrity of the six MSA patient-derived iPSCs. (A) Short tandem repeat profiling provided the number of repeating units of 16 polymorphic microsatellite loci, to compare the donor fibroblast cells (reference) and the generated iPSCs and verify their origin. (B) G-banding revealed that the six iPSC lines showed a normal diploid karyotype (n = 46) and matched the sex of the donor patient. (C) Digital PCR allowed us to screen whether specific genomic regions accumulated duplications that may give a strong selective survival or growth advantage to iPSCs. Example of the scatter digital PCR plots displaying simultaneously (1) FAM signals, shown in purple and green to detect the target gene ( ID1 , NCAPD2 , PITX1 , RPS6KB1 , SOAT1 , or STS ), which are located in the 6 most recurrent abnormal regions; and (2) VIM signals, shown in orange and green to detect the reference gene, RPP30 . The ratio between the number of copies of the target gene and of the reference gene was used to determine the normal 2-copy number or copy number variations. The plots were obtained through QuantStudio 3D Digital PCR system. In all cases, we obtained 2-copy number (D) Quantitative Real Time RT-PCR was used for confirming the absence of the Sendai virus in the iPSC lines after 8 passages, through four primer sets (SeV, KOS, Klf4 and c-Myc). Box and Whisker plots depict in log10 scale the gene expression relative to GAPDH gene and normalized to the 7 days post-transduction fibroblasts, calculated by the 2(-ΔΔC(T)) method. In all iPSC clones, the expression levels of the SeV RNA were very low, reaching the limit of detection. Data are shown as the mean ± s.d. n = 3.

Article Title: Reduced cytochrome P-450 (CYP) 2D6 activity and Plasmodium vivax malaria risk in Amazonians: A retrospective, population-based cohort study

doi: 10.1371/journal.pntd.0014160

Figure Lengend Snippet: Three CYP2D6 activity levels were defined: null/low (genotype-determined activity score [AS] ≤ 0.25), intermediate (AS between 0.5 and 1.0), and normal/high (AS > 1.0). The shaded areas surrounding the lines represent 95% confidence intervals. The P value of 0.0237 was obtained with a log-rank test comparing the three survival curves, rejecting the null hypothesis that groups with different CYP2D6 activity levels share an identical survival curve.

Article Snippet: The Hs00010001_cn assay (Thermo Fisher Scientific) was used estimate the CYP2D6 gene copy number; activity values were multiplied when multiple CYP2D6 allele copies were present ( ).
