Endocytosis functions together with lysosomal proteolysis to facilitate necrotic cell death.Figure 3Endocytosis functions together with lysosomal proteolysis to facilitate necrotic cell death. (A) Depletion of synaptotagmin (SNT‐1) or endophilin (UNC‐57) does not further suppress MEC‐4(d)‐induced necrosis in cad‐1 mutants with reduced cathepsin activity or with V‐ATPase dysfunction (B, C). Similarly, no synthetic reduction of necrotic cell death is observed in calpain‐deficient animals that also carry lesions in the synaptotagmin (D) or endophilin (E) genes.

Figure 6Scheme illustrating the independent mechanisms of replication-coupled and SUMO-mediated replication-independent DPC repair available to cells. In the absence of RNF4-mediated DPC resolution, cells containing high loads of DPCs generated after DNA replication fail to elicit a DNA damage checkpoint response and consequently enter mitosis with unresolved DPCs, leading to chromosome segregation defects.

Figure 5For each codon, the average frequency (per thousand) is compared between transcripts induced but offset vs non-offset (i.e. abundance mode of regulation) upon ERα depletion in BM67 cells. Codons for the same amino acid are connected by a gray line. Heatmap of standardized residuals from a chi-squared contingency table test. Shown in red and blue are cells with counts significantly higher and lower, respectively, than expected counts under the null hypothesis (i.e. independence between mode for regulation of gene expression and codon composition). A correspondence analysis for average codon frequency among transcripts annotated to each GO term. Each gray dot corresponds to one GO term. The gene expression modes observed upon ERα depletion (Fig 1E) were then projected into the same dimensions based on the average codon frequencies of included transcripts.

Codons identified as over-represented among translationally offset mRNAs are also indicated. Unsupervised clustering of gene level codon usage normalized by amino acid counts. All regulated mRNAs (from Fig 1E) are shown in rows and all codons in columns. Codons identified as over-represented among mRNAs whose levels were induced but offset or suppressed but offset are indicated in light and dark blue, respectively.
