Examples of Amino Acid Changes in Notothenioids Methods To
Supplementary Information S1 Candidate genes: examples of amino acid changes in notothenioids Methods To evaluate notothenioid amino acid changes in a cross‐section of genes, six candidates from a range of functional categories of interest were chosen for a more detailed examination. The selected genes comprised small, well‐characterised genes present in multiple fish species (mainly teleosts, but in some cases these analyses were extended to the Actinopterygii when sequences from the spotted gar (Lepisosteus oculatus) were available) and available in at least two notothenioids. The amino acid composition of a series of six candidate genes were further analysed in depth at the amino acid sequence level. These genes were superoxide dismutase 1 (SOD1), neuroglobin, dihydrofolate reductase (both paralogues), p53 and calmodulin. Clustal X alignments were constructed from orthologues identified in the four Notothenioid transcriptomes along with other fish orthologues extracted from either SwissProt (Bateman et al., 2017) or Ensembl release 91 (Aken et al., 2017). Alignment data were visualised and annotated in BoxShade version 3.21 (https://embnet.vital‐ it.ch/software/BOX_form.html). Notothenioid‐specific changes were noted and the type of substitution in terms of amino acid properties was noted. Results A range of amino acid changes were revealed, from virtually complete conservation between the notothenioids and other fish (calmodulin), to one amino acid substitution present in neuroglobin and SOD1, to more extensive changes in dihydrofolate reductase, dihydrofolate reductase‐like and p53. In the case of the latter three genes, notothenioid‐specific changes were at positions that were often highly variable in temperate fish species with up to six different amino acid substitutions and did not result in a definable pattern of directional substitution. -
MAP2K3 (Human) Recombinant Protein (Q01)

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -

Der1,2* Stabilization of the MYC oncoprotein by KRAS signaling critically promotes the growth of pancreatic ductal adeno- carcinoma (PDAC). Thus, understanding how MYC protein stability is regulated may lead to effective therapies. Here, we used a previously developed, flow cytometry–based assay that screened a library of >800 protein kinase inhibitors and identified compounds that promoted either the stability or degradation of MYC in a KRAS-mutant PDAC cell line. We validated compounds that stabilized or destabilized MYC and then focused on one compound, Downloaded from UNC10112785, that induced the substantial loss of MYC protein in both two-dimensional (2D) and 3D cell cultures. We determined that this compound is a potent CDK9 inhibitor with a previously uncharacterized scaffold, caused MYC loss through both transcriptional and posttranslational mechanisms, and suppresses PDAC anchorage- dependent and anchorage-independent growth. We discovered that CDK9 enhanced MYC protein stability 62 through a previously unknown, KRAS-independent mechanism involving direct phosphorylation of MYC at Ser . -

Integrated Molecular Characterisation of the MAPK Pathways in Human
ARTICLE https://doi.org/10.1038/s42003-020-01552-6 OPEN Integrated molecular characterisation of the MAPK pathways in human cancers reveals pharmacologically vulnerable mutations and gene dependencies 1234567890():,; ✉ Musalula Sinkala 1 , Panji Nkhoma 2, Nicola Mulder 1 & Darren Patrick Martin1 The mitogen-activated protein kinase (MAPK) pathways are crucial regulators of the cellular processes that fuel the malignant transformation of normal cells. The molecular aberrations which lead to cancer involve mutations in, and transcription variations of, various MAPK pathway genes. Here, we examine the genome sequences of 40,848 patient-derived tumours representing 101 distinct human cancers to identify cancer-associated mutations in MAPK signalling pathway genes. We show that patients with tumours that have mutations within genes of the ERK-1/2 pathway, the p38 pathways, or multiple MAPK pathway modules, tend to have worse disease outcomes than patients with tumours that have no mutations within the MAPK pathways genes. Furthermore, by integrating information extracted from various large-scale molecular datasets, we expose the relationship between the fitness of cancer cells after CRISPR mediated gene knockout of MAPK pathway genes, and their dose-responses to MAPK pathway inhibitors. Besides providing new insights into MAPK pathways, we unearth vulnerabilities in specific pathway genes that are reflected in the re sponses of cancer cells to MAPK targeting drugs: a revelation with great potential for guiding the development of innovative therapies. -

ABSTRACT Somatic mutations of the epidermal growth factor receptor often cause resistance to therapy with tyrosine kinase inhibitor in non-small cell lung cancer (NSCLC). In this study, we aimed to identify partner drugs and pathways that can induce cell death in combination with gefitinib in NSCLC cells. We undertook a genome-wide RNAi screen to identify synthetic lethality with gefitinib in tyrosine kinase inhibitor resistant cells. The screening data were utilized in different approaches. Firstly, we identifiedPRKCSH as a candidate gene, silencing of which induces apoptosis of NSCLC cells treated with gefitinib. Next, in an in silico gene signature pathway analysis of shRNA library data, a strong correlation of genes involved in the CD27 signaling cascade was observed. -

In the present study, we examined this involvement in human hepatoma cell lines using a human TLR signaling target RT-PCR array. We also observed that zinc chloride inhibited mitogen-activated protein kinase kinase 3 (MAP2K3) expression, which could downregulate HAV replication in human hepatocytes. It is possible that zinc chloride may inhibit HAV replication in association with its inhibition of MAP2K3. In that regard, this study set out to determine whether MAP2K3 could be considered a modulating factor in the development of the HAV pathogen-associated molecular pattern (PAMP) Citation: Kanda, T.; Sasaki-Tanaka, and its triggering of interferon-β production. -
