| T1 |
0-120 |
Sentence |
denotes |
Expression profiling and regulation of genes related to silkworm posterior silk gland development and fibroin synthesis. |
| T2 |
121-269 |
Sentence |
denotes |
The posterior silk gland (PSG) is the most important suborgan responsible for the synthesis and secretion of silk core fibroin proteins in silkworm. |
| T3 |
270-504 |
Sentence |
denotes |
Here, we performed genome-scale expression profiling analysis of silkworm PSG at the fourth molting (M4) and at day 1 (V1), day 3 (V3), day 5 (V5), and wandering stage (W) of the fifth instar by microarray analysis with 22 987 probes. |
| T4 |
505-746 |
Sentence |
denotes |
We found that the five genes of silk proteins secreted from PSG including fibroin heavy (H) and light (L) chains, P25, seroin 1, and seroin 2 basically showed obvious up-regulation at V3 which lasted to V5, while slight down-regulation at W. |
| T5 |
747-941 |
Sentence |
denotes |
The expression of translation-related genes including ribosomal proteins and translation initiation factors generally remained stable from M4 to V5, whereas it showed clear down-regulation at W. |
| T6 |
942-1220 |
Sentence |
denotes |
Clustering analysis of the 643 significantly differentially expressed transcripts revealed that 43 of the important genes including seroin 1 and sugar transporter protein had co-expression patterns which were consistent with the rate changes of fibroin synthesis and PSG growth. |
| T7 |
1221-1335 |
Sentence |
denotes |
Pathway analysis disclosed that the genes in different clusters might have co-regulations and direct interactions. |
| T8 |
1336-1416 |
Sentence |
denotes |
These genes were supposed to be involved in the fibroin synthesis and secretion. |
| T9 |
1417-1568 |
Sentence |
denotes |
The differential expression of several hormone-related genes also suggested their functions on the regulation of PSG development and fibroin synthesis. |
| T10 |
1569-1804 |
Sentence |
denotes |
2D gel-based proteomics and phosphoproteomics profiling revealed that the phosphorylated proteins accounted for no more than one-sixth of the total proteins at each stage, which was much lower than the level in normal eukaryotic cells. |
| T11 |
1805-1993 |
Sentence |
denotes |
Changes in the phosphorylation status and levels of several proteins such as actin-depolymerizing factor 1 and enolase might be deeply involved in fibroin secretion and tissue development. |
| T12 |
1994-2339 |
Sentence |
denotes |
Shotgun proteomic profiling combined with label-free quantification analysis on the PSG at V3, V5, and W revealed that many small heat shock proteins (sHSP) were specially expressed at W, which was substantially consistent with the results from 2-DE analysis, and implied the close correlations of sHSP with the physiological states of PSG at W. |
| T13 |
2340-2588 |
Sentence |
denotes |
A majority of significantly up-regulated proteins at V5 were related to ribosome pathway, which was different from the microarray results, implying that the translation-level regulation of ribosomal proteins might be critical for fibroin synthesis. |
| T14 |
2589-2787 |
Sentence |
denotes |
In contrast, the ubiquitin-proteasome pathway related proteins appeared obviously up-regulated at W, suggesting that the programmed cell death process of PSG cells might be started before cocooning. |
