[HLA, A, B, C, DR, C4, Bf in insulin-dependent diabetics in the Tunisian population].
|
5 |
2648900
|
The frequency of HLA-A-B and DR antigens as well as the Bf and C4 allotypes have been investigated in insulinodependant diabetes mellitus (IDDM) and compared to that of healthy controls in Tunisian population.
|
6 |
2648900
|
An increase of A30, DR3, DR4, BfF1, C4AQ0 and C4BQ0 and decrease of B40, DR2, DR5 and DR6 were found in diabetes when compared to the value observation controls.
|

2648900
|
The strongest association was noticed with HLA, DR3 and DR4.

|
9 |
2714046
|
An increase of A30, DR3, DR4, BfF1, C4Ao, and C4Bo and decrease of B40, DR2, DR5, and DR6 were found in diabetics when compared to the value observed in controls.
|
10 |
2714046
|
The strongest association was noticed with HLA DR3 and DR4.

|
Heterozygotes DR3 DR4 were very frequent in diabetics: 24.2 per cent versus 3.6 per cent in controls (relative risk 7.72).
|
12 |
2979618
|
DR3 and DR4 have been the most positive and DR2 the most negative.
|
13 |
2979618
|
In 952 Caucasian proband patients reported here, only 57 or 6% had no DR3 or DR4 alleles.
|
14 |
2979618
|
When these 57 patients were compared to 249 Caucasian controls similarly lacking DR3 and DR4 antigens, there were excesses of DR1 (P = 0.13) and DRW8 (P = 0.01) and deficiencies of DR2 (P = 0.03) and DR5 (P = 0.03) in the patient group.
|
15 |
2979618
|
Only four DR-homozygous patients involving alleles other than DR3 and DR4 were found by genotyping, and all were DR1 homozygotes.
|
16 |
2979618
|
We conclude that DR1 is an additional risk DR allele for IDD to that of DR3 and DR4, and DR5 an additional protective DR allele to that of DR2.

3545954
|
The Type 1 diabetic patients showed a typical HLA pattern, with increased frequencies of B15, DR3, DR4, B8/B15 and DR3/DR4 and decreased frequencies of B7 and DR2.
|
21 |
3545954
|
The Type 2 diabetic patients could be distinguished from blood donors by increased frequencies of Cw4, DR4, DR5 and DR3/DR4, and from Type 1 diabetic patients by increased frequencies of B7, DR2, DR5 and decreased frequency of A9, Bw22 and DR4.
|
22 |
3545954
|
Age at onset and body mass index were unrelated to HLA antigens, but the Type 2 diabetic patients with HLA-Cw4, DR5 and DR6 showed a strong family history for Type 2 diabetes.
|
23 |
3545954
|
Type 2 diabetic patients with HLA-B8, DR4, B8/B15 and DR3/DR4 showed significantly lower C-peptide concentrations (p less than 0.05) than patients without these HLA antigens.
|
24 |
3545954
|
Twelve patients who were positive for both DR3 and DR4 and 23 patients who were DR3/DR4 negative were followed with repeated C-peptide determinations during a period of three years.
|
25 |
3545954
|
The C-peptide concentrations of the DR3/DR4 positive patients decreased during this period, whereas there was no change in C-peptide levels in the DR3/DR4 negative patients.

Fifty juvenile insulin dependent diabetes mellitus (JIDDM) patients of Tamil Nadu (South India) were typed for HLA-A, -B, -C, -DR, and -DQ, ESD, GLOI, C3 and HP polymorphisms.
|
37 |
7835212
|
The frequencies of B8, DR3, DR4, DR53 and DQ2 antigens of the HLA system were significantly higher in the patients than in controls (relative risk, RR = 4.81; 5.14; 3.98; 3.36 and 2.53, respectively).
|
38 |
7835212
|
However HLA-DR2, -DR5 and -DQ1, observed less frequently in the patient group, appear to play a role of protection against the disease (RR = 0.32; 0.30 and 0.20 respectively).

Induction and intracellular regulation of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) mediated apotosis in human malignant glioma cells.
|
42 |
11221847
|
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) preferentially triggers apoptosis in tumor cells versus normal cells, thus providing a therapeutic potential.
|
43 |
11221847
|
TRAIL-induced cell death was characterized by activation of caspase-8 and -3, poly(ADP-ribose) polymerase cleavage, and DNA fragmentation.
|
44 |
11221847
|
Decoy receptor (DcR1 and DcR2) expression was limited in the glioma cell lines and did not correlate with TRAIL sensitivity.
|
45 |
11221847
|
Both sensitive and resistant cell lines expressed TRAIL death receptor (DR5), adapter protein Fas-associated death domain (FADD), and caspase-8; but resistant cell lines expressed 2-fold higher levels of the apoptosis inhibitor phosphoprotein enriched in diabetes/phosphoprotein enriched in astrocytes-15 kDa (PED/PEA-15).
|
46 |
11221847
|
In contrast, cellular FADD-like IL-1beta-converting enzyme-like inhibitory protein (cFLIP) expression was similar in sensitive and resistant cells.
|
47 |
11221847
|
Inhibition of protein kinase C (PKC) activity restored TRAIL sensitivity in resistant cells, suggesting that PED/ PEA-15 function might be dependent on PKC-mediated phosphorylation.
|
48 |
11221847
|
This caspase-8-induced apoptotic cascade is regulated by intracellular PED/PEA-15, but not by cFLIP or decoy receptors.

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has been shown to exert potent cytotoxic activity against many tumor cells but not normal cells.
|
50 |
12706864
|
We found that most TRAIL-resistant and -partial resistant clones expressed low levels of DR5, whereas most TRAIL-sensitive clones expressed high levels of Death Receptor (DR5).
|
51 |
12706864
|
However, there were clones with a range of different TRAIL-sensitivities that had similar levels of DR5 expression.
|
52 |
12706864
|
The expression levels of DR4 and the decoy receptors, DcR1 and DcR2, did not correlate with TRAIL sensitivities.
|
53 |
12706864
|
We also compared the subgroups in terms of the expression of Fas-associated death domain protein (FADD), the levels of activation of Receptor Interacting Protein (RIP) and caspases, and cleavage of Poly (ADP-Ribose)Polymerase (PARP).
|
54 |
12706864
|
After treatment with TRAIL, both TRAIL-sensitive and partial resistant clones showed high levels of activation of caspase-3, caspase-8, RIP and PARP.
|
55 |
12706864
|
Relative basal level and induced level of Phosphoprotein over Expressed in Diabetes/Phosphoprotein Enriched in Astrocytes (PED/PEA-15) after TRAIL treatment were compared in the clones.
|
56 |
12706864
|
TRAIL did not change the PED/PEA-15 level in the clones.
|
57 |
12706864
|
In addition, transduction and expression of the dominant negative form of the I-kBalpha gene did not change TRAIL-sensitivities.
|
58 |
12706864

Immunohistochemistry displayed a greater amount of TNF-related apoptosis-inducing ligand (TRAIL) and KILLER, a key murine ligand and receptor involved in the extrinsic pathway, expressed in cumulus cells from hyperglycemic mice compared with controls, suggesting that this apoptotic pathway may be up-regulated under diabetic stress.

Human astrocytes are resistant to Fas ligand and tumor necrosis factor-related apoptosis-inducing ligand-induced apoptosis.
|
81 |
16554480
|
Here, we report that calcium/calmodulin-dependent protein kinase II (CaMKII) is constitutively activated in human astrocytes and protects the cells from apoptotic stimulation by Fas agonist.
|
82 |
16554480
|
Once stimulated, Fas recruits Fas-associated death domain and caspase-8 for the assembly of the death-inducing signaling complex (DISC); however, caspase-8 cleavage is inhibited in the DISC.
|
83 |
16554480
|
Inhibition of CaMKII kinase activity inhibits the expression of phosphoprotein enriched astrocytes-15 kDa/phosphoprotein enriched in diabetes (PEA-15/PED) and cellular Fas-associated death domain-like interleukin-1beta-converting enzyme-inhibitory protein (c-FLIP), thus releasing their inhibition of caspase-8 cleavage.
|
84 |
16554480
|
Inhibition of PEA-15/PED or c-FLIP by small interfering RNA sensitizes human astrocytes to Fas-induced apoptosis.
|
85 |
16554480
|
In contrast, inhibition of CaMKII, PEA-15, or c-FLIP does not affect the sensitivity of human astrocytes to tumor necrosis factor-related apoptosis-inducing ligand (TRAIL).
|
86 |
16554480
|
TRAIL death receptors (DR4, DR5) are weakly expressed at mRNA, protein, and cell surface levels and thus fail to mediate the assembly of the DISC in human astrocytes.
|
87 |
16554480
|
Overexpression of DR5 restores TRAIL signaling pathways and sensitizes the human astrocytes to TRAIL-induced apoptosis if CaMKII kinase activity or expression of PEA-15 and c-FLIP is inhibited; the results suggest that CaMKII-mediated pathways prevent TRAIL-induced apoptosis in human astrocytes under conditions in which TRAIL death receptors are upregulated.
|
88 |
16554480

This study has therefore identified the molecular mechanisms that protect normal human astrocytes from apoptosis induced by Fas ligand and TRAIL.

DR5-mediated DISC controls caspase-8 cleavage and initiation of apoptosis in human glioblastomas.
|
101 |
19432816
|
TRAIL has four membrane-anchored receptors, death receptor 4/5 (DR4/5) and decoy receptor 1/2 (DcR1/2).
|
102 |
19432816
|
Of these receptors, only DR5 was expressed consistently in glioblastoma cell lines and tumour tissues, ruling out the role of DcR1/2 in TRAIL resistance.
|
103 |
19432816
|
Upon TRAIL binding, DR5 was homotrimerized and recruited Fas-associated death domain (FADD) and caspase-8 for the assembly of death-inducing signalling complex (DISC) in the lipid rafts of the plasma membrane.
|
104 |
19432816
|
In the DISC, caspase-8 was cleaved and initiated apoptosis by cleaving downstream caspases in TRAIL-sensitive glioblastoma cells.
|
105 |
19432816
|
In TRAIL-resistant cells, however, DR5-mediated DISC was modified by receptor-interacting protein (RIP), cellular FADD-like interleukin-1beta-converting enzyme inhibitory protein (c-FLIP) and phosphoprotein enriched in diabetes or in astrocyte-15 (PED/PEA-15).
|
106 |
19432816
|
This DISC modification occurred in the non-raft fractions of the plasma membrane and resulted in the inhibition of caspase-8 cleavage and activation of nuclear factor-kappaB (NF-kappaB).
|
107 |
19432816
|
Treatment of resistant cells with parthenolide, an inhibitor of inhibitor of kappaB (I-kappaB), eliminated TRAIL-induced NF-kappaB activity but not TRAIL resistance.
|
108 |
19432816
|
In contrast, however, targeting of RIP, c-FLIP or PED/PEA-15 with small interfering RNA (siRNA) led to the redistribution of the DISC from non-rafts to lipid rafts and eliminated the inhibition of caspase-8 cleavage and thereby TRAIL resistance.
|
109 |
19432816
|
Taken together, this study indicates that the DISC modification by RIP, c-FLIP and PED/PEA-15 is the most upstream event in TRAIL resistance in glioblastomas.

|
In contrast, however, targeting of RIP, c-FLIP or PED/PEA-15 with small interfering RNA (siRNA) led to the redistribution of the DISC from non-rafts to lipid rafts and eliminated the inhibition of caspase-8 cleavage and thereby TRAIL resistance.
|
129 |
19432816
|
Taken together, this study indicates that the DISC modification by RIP, c-FLIP and PED/PEA-15 is the most upstream event in TRAIL resistance in glioblastomas.

DR5-mediated DISC controls caspase-8 cleavage and initiation of apoptosis in human glioblastomas.
|

TRAIL has four membrane-anchored receptors, death receptor 4/5 (DR4/5) and decoy receptor 1/2 (DcR1/2).
|
132 |
19432816
|
Of these receptors, only DR5 was expressed consistently in glioblastoma cell lines and tumour tissues, ruling out the role of DcR1/2 in TRAIL resistance.
|
133 |
19432816
|
Upon TRAIL binding, DR5 was homotrimerized and recruited Fas-associated death domain (FADD) and caspase-8 for the assembly of death-inducing signalling complex (DISC) in the lipid rafts of the plasma membrane.
|
134 |
19432816
|
In the DISC, caspase-8 was cleaved and initiated apoptosis by cleaving downstream caspases in TRAIL-sensitive glioblastoma cells.
|
135 |
19432816
|
In TRAIL-resistant cells, however, DR5-mediated DISC was modified by receptor-interacting protein (RIP), cellular FADD-like interleukin-1beta-converting enzyme inhibitory protein (c-FLIP) and phosphoprotein enriched in diabetes or in astrocyte-15 (PED/PEA-15).
|
136 |
19432816
|
This DISC modification occurred in the non-raft fractions of the plasma membrane and resulted in the inhibition of caspase-8 cleavage and activation of nuclear factor-kappaB (NF-kappaB).

A previous study found that TRAIL did not have significant cytotoxic effects on the insulin-secreting pancreatic beta cell line, INS-1.
|
144 |

|
TRAIL treatment showed NF-kappaB translocation to the nucleus in TRAIL-resistant INS-1 cells, and TRAIL-induced NF-kappaB activation was preceded by IkappaBalpha degradation.

Four related receptors bind TRAIL: two death receptors (DR4 and DR5) that promote apoptosis, and two decoy receptors (DcR1 and DcR2) that act as dominant-negative inhibitors of TRAIL-mediated apoptosis.
|
147 |
20451496
|
In the present study, TRAIL treatment in INS-1 cells upregulated DcR1 and downregulated DR5 without altering the expression of DcR2 and DR4.
|
148 |
20451496
|
The resistance to apoptosis in INS-1 cells might therefore, be a consequence of DcR1 upregulation and DR5 downregulation, and the transcription factor, NF-kappaB, could regulate the sensitivity of cells to TRAIL by controlling the ratio of decoy to death receptors.
|
149 |
20451496

Thus, TRAIL may play an important role in the survival of pancreatic beta cells by regulating receptor expression in an NF-kappaB-dependent manner.

The immunohistochemical study revealed increased immunostaining of TRAIL and DR5 in osteoblastic cells of the diaphysis (pre-metaphysis) and epiphysis treated with STZ and L-NAME, related to activation of osteoblastic apoptotic death, while the group receiving L-arginine was comparable to the control group and the higher indications of iNOS activity that may reflect its induction by L-arginine administration.

|
Cancer-associated ATF3 is involved in regulation of distinct sets of genes in processes such as calcium signalling, Wnt, p53 and diabetes pathways.
|
173 |
22046379
|
Notably, stress-induced ATF3 binds to 40% of p53 targets and activates pro-apoptotic genes such as TNFRSF10B/DR5 and BBC3/PUMA.
|
174 |
22046379
|
Cancer-associated ATF3, by contrast, represses these pro-apoptotic genes in addition to CDKN1A/p21.
|

|
Taken together, our data reveal an extensive network of stress-inducible transcription factors and demonstrate that ATF3 has opposing, cell context-dependent effects on p53 target genes in DNA damage response and cancer development.
