Are the gene in gene-dense region more expressed compared to the gene in gene desert region?

I want to know how alternative splicing, speckles localisation and expression of gene is affected by its position in gene dense and gene desert region.

Where can I get the information about human genes which are enriched in speckles for either their expression or splicing?

I need to know the gene rich region on chromosome in human which localize in speckles for their expression and splicing compare to other genes which don't depend on speckles localization.

Which virus can be considered as clever virus? Can we tell because it escapes from our immune system like HIV or are some viruses clever?

Many people think that flu virus is the most clever. But how can we measure intelligence of virus and bacteria? Is that pathogenesis, escaping from immune system or no vaccine?

Is it possible for two human neuronal cell lines to have different gene sequence for the same protein?

I am looking at the ATP1A2 (Sodium/Potassium ATPase alpha subunit 2) in two human neuronal cell lines. Expression levels of this protein seems to be almost equal when detected by one antibody....

Any specific pipeline or parameter to analyse total transcriptomics study of brain tissue samples?

I have two groups of brain samples, control and treated for example. It was total RNA nova seq sequencing. I tried all the available pipeline like: star+rsem+deseq2, Hista+stringtie+cuffdiff,...

RNA-seq DEGs downstream analysis and reporting in literature?

I used EdgeR to get the list of DEGs (differentially expressed genes) from my liver RNA-seq experiment. I have done the gene overrepresentation and GSEA based pathway analysis. I am currently...

Are there any databases for gene co-expression or expression pattern clustering?

I am currently working on gene clustering based on co-expression pattern in mouse brain. The problem is I do not have some solid way to test my result. Are there any suggestions for databases...

Which CpGs have a significant effect on gene expression?

It is known that methylated CpG around TSS decreases gene expression. However, It is difficult to know exactly which CpG has a greater impact on gene expression. Are there any databases known...

I can detect my protein but the encoding DNA sequence has stop codons within. Should I ignore the stop codons?

I constructed a synthetic DNA library (scFv, VH-VL orientation) with a 3' reporter and 8x histag. I cloned and expressed this gene following which I performed an ELISA. The ELISA results suggested...
