Inhibition of tumor intrinsic BANF1 activates antitumor immune responses via cGAS-STING and enhances the efficacy of PD-1 blockade
Introduction Immune checkpoint inhibitors (ICIs) have revolutionized the treatment pattern of various cancers, including melanoma and non-small cell lung cancer (NSCLC).1–3 However, there are still a considerable proportion (40%–60%) of patients who do not respond or do not achieve durable responses to these drugs.4 Thus, it is urgent clinical need…

Microbiome-directed foods boost child nutrition
In a recent study posted to the medRxiv* preprint server, researchers reconstructed gut bacterial genomes. The study identified metabolic pathways that are differentially expressed in response to a microbiota-directed complementary food prototype (MDCF-2) in metagenome-assembled genomes (MAGs) related to changes in weight-for-length Z scores (WLZ). They also evaluated the impact…
Identification of a two metastasis-related prognostic signature in the process of predicting the survival of laryngeal squamous cell carcinoma
Identification and functional analysis of 73 DEMRGs A total of 73 DEMRGs were identified between N0 samples and N1/N2/N3 samples of LSCC, including 59 up-regulated and 14 down-regulated genes in N0 samples relative to N1/N2/N3 samples (Fig. 1a, Supplementary Table 1). The expressions of DEMRGs were present in the heatmap (Fig. 1b)….

The study received ethics approval from the North West Multi-center Research Ethics Committee. All participants signed written informed consent before participating. WES data for 450,000 subjects were…
Over Representation Analysis over one specific pathway
Over Representation Analysis over one specific pathway 0 Hi! Let’s say I would like to analyse if a particular pathway is enriched how would I do that given that I have a set of DGE genes resulting from 1500 genes of RNA Seq? I do not want to analise any…
how to check if DE genes are enriched in custom genomic regions derived from epigenetic data
Al , first head to the msigdb website, and take a look at the annotations that belong to set C1: www.gsea-msigdb.org/gsea/msigdb/human/collections.jsp#C1. Note that, while C1 contains gene sets defined based on position, the others are quite different (e.g. C2 is “curated”, C8 is “cell type signatures”) and so forth. the…
Gene set enrichment analysis / Kegg analysis
Gene set enrichment analysis / Kegg analysis 0 Hi all, I recently did differential gene expression of Daphnia magna using DESeq2 in R studio. It was my first time doing the analysis. Now the next step is to conduct Kegg analysis or Gene set enrichment analysis of the differentially expressed…
Bioinformatics analysis of hedgehog interacting protein in colorectal cancer: a study based on GEO data and TCGA data | BMC Gastroenterology
HHIP was lowly expressed in CRC tissues and HHIP expression was associated with cancer patient prognosis We acquired the RNA-sequencing data of CRC from TCGA public database. To pursue possible roles of HHIP in carcinostasis, we first analyzed HHIP expression in 33 types of human cancers. As shown in Fig. 1A,…
