Database of human genes encoding cell surface proteins
... Hello, I am looking for a database of human genes encoding proteins on the cell surface (of any human cell type). Where may I find such a list? I have come across the human protein atlas but unable to find an obvious way to get the protein from it. Thanks ...

List of Human Cell Cycle Stage Specific Genes
... Hi, I am looking for genes that are specifically expressed in specific stages of the cell cycle. So for example, in the G1 (until G1/S) phase, CDT1 is preferentially expressed. In mid-S to late S, Gemenin is expressed. Where can I get an exhaustive list of *human* genes in: G1, S, G2 and M phases? T ...

Comment: A: Survival analysis of TCGA patients integrating gene expression (RNASeq) data
... I am interested in looking only upto 5 years (1825 days). I'm new to survival analysis. Is it correct to discard all the samples whose max(days_to_last_known_alive, days_to_last_followup) is <=1825 by doing this: all_clin=all_clin[all_clin$new_death <= 1825,] Is this correct? (I have ...

Comment: A: Survival analysis of TCGA patients integrating gene expression (RNASeq) data
... The histogram of z-scores is not quite symmetric, it tends to have a heavier tail on the lower end (i.e. there are more genes below summit) so it does not look like that > 1.96 is equivalent to p=0.05 (my guess is that it is much lower than that. Similarly, I don't think that the Z < -1.96 is ...
