Abstract
Staphylococcus aureus is a dangerous pathogen that evolved refined immuno-evasive strategies to antagonize host immune responses. This involves the biogenesis of death-effector deoxyribonucleosides, which kill infectious foci-penetrating macrophages. However, the exact mechanisms whereby staphylococcal death-effector deoxyribonucleosides and coupled imbalances of intracellular deoxyribonucleotide species provoke immune cell death remain elusive. Here, we report that S. aureus systematically promotes an overload of deoxyribonucleotides to trigger mitochondrial rupture in macrophages, a fatal event that induces assembly of the caspase-9-processing apoptosome and subsequent activation of the intrinsic pathway of apoptosis. Remarkably, genetic disruption of this cascade not only helps macrophages coping with death-effector deoxyribonucleoside-mediated cytotoxicity but also enhances their infiltration into abscesses thereby ameliorating pathogen control and infectious disease outcomes in laboratory animals. Combined with the discovery of protective alleles in human CASP9, these data highlight the role of mitochondria-centered apoptosis during S. aureus infection and suggest that gene polymorphisms may shape human susceptibility toward a predominant pathogen.

Abstract
Caspases are proteolytic enzymes that belong to the cysteine protease family and play a crucial role in homeostasis and programmed cell death. Caspases have been broadly classified by their known roles in apoptosis (caspase-3, caspase-6, caspase-7, caspase-8, and caspase-9 in mammals) and in inflammation (caspase-1, caspase-4, caspase-5, and caspase-12 in humans, and caspase-1, caspase-11, and caspase-12 in mice). Caspases involved in apoptosis have been subclassified by their mechanism of action as either initiator caspases (caspase-8 and caspase-9) or executioner caspases (caspase-3, caspase-6, and caspase-7). Caspases that participate in apoptosis are inhibited by proteins known as inhibitors of apoptosis (IAPs). In addition to apoptosis, caspases play a role in necroptosis, pyroptosis, and autophagy, which are non-apoptotic cell death processes. Dysregulation of caspases features prominently in many human diseases, including cancer, autoimmunity, and neurodegenerative disorders, and increasing evidence shows that altering caspase activity can confer therapeutic benefits. This review covers the different types of caspases, their functions, and their physiological and biological activities and roles in different organisms.

Abstract
Even if adoptive cell transfer (ACT) has already shown great clinical efficiency in different types of disease, such as cancer, some adverse events consistently occur, and suicide genes are an interesting system to manage these events. Our team developed a new medical drug candidate, a chimeric antigen receptor (CAR) targeting interleukin-1 receptor accessory protein (IL-1RAP), which needs to be evaluated in clinical trials with a clinically applicable suicide gene system. To prevent side effects and ensure the safety of our candidate, we devised two constructs carrying an inducible suicide gene, RapaCasp9-G or RapaCasp9-A, containing a single-nucleotide polymorphism (rs1052576) affecting the efficiency of endogenous caspase 9. These suicide genes are activated by rapamycin and based on the fusion of human caspase 9 with a modified human FK-binding protein, allowing conditional dimerization. RapaCasp9-G- and RapaCasp9-A-expressing gene-modified T cells (GMTCs) were produced from healthy donors (HDs) and acute myeloid leukemia (AML) donors. The RapaCasp9-G suicide gene demonstrated better efficiency, and we showed its in vitro functionality in different clinically relevant culture conditions. Moreover, as rapamycin is not pharmacologically inert, we also demonstrated its safe use as part of our therapy.

Abstract
Caspase-9 (CASP9) and caspase-10 (CASP10) polymorphisms were associated with human cancers; however, the results remain controversial. In this meta-analysis, we aimed to estimate the relationship among CASP9 (rs1052576, rs1052571, rs4645978, rs4645981, rs4645982, rs2308950) and CASP10 (rs13006529, rs13010627, rs3900115) polymorphisms and the overall risk of cancers. Relevant studies were obtained from Web of Science, MEDLINE, PubMed, Scopus, and Google scholar databases (updated January 1, 2021). Odds ratio (OR) and 95% confidence intervals (CIs) were measured to estimate the strength of association. Our meta-analysis included 40 studies. The rs4645981 significantly enhanced the risk of cancer under TT vs. CC (OR = 2.42), TC vs. CC (OR = 1.55), TT+ TC vs. CC (OR = 1.66), TT vs. TC + CC (OR = 1.91), and T vs. C (OR = 1.57) inheritance models. As for the rs1052571 variant, increased risk of cancer was observed under TT vs. CC (OR =1.22), TC vs. CC (OR = 1.17), and TT+ TC vs. CC (OR = 1.18) models. The stratified analysis showed a significant correlation between rs4645978 or rs4645981 polymorphisms and cancer risk, while in Asians rs4645978 conferred an increased risk of colorectal, lung, and prostate cancer. Both rs4645981 and rs1052576 polymorphisms were correlated with an enhanced risk of lung cancer. In conclusion, our meta-analysis suggested that CASP9 rs4645981 and rs1052571 polymorphisms are associated with overall cancer risk. More studies on larger populations are warranted to validate these associations.

Abstract
Caspase-9, a cysteine-aspartic protease known for its role as an initiator of intrinsic apoptosis, regulates physiological cell death and pathological tissue degeneration. Its nonapoptotic functions, including regulation of cellular differentiation/maturation, innate immunity, mitochondrial homeostasis, and autophagy, reveal a multimodal landscape of caspase-9 functions in health and disease. Recent work has demonstrated that caspase-9 can drive neurovascular injury through nonapoptotic endothelial cell dysfunction. CASP9 polymorphisms have been linked with various cancers, neurological disorders, autoimmune pathologies and lumbar disc disease. Clinical reports suggest alterations in caspase-9 expression, activity or function may be associated with acute and chronic neurodegeneration, retinal neuropathy, slow-channel myasthenic syndrome, lumbar disc disease, cardiomyopathies, atherosclerosis and autoimmune disease. Healthy tissues maintain caspase-9 activity at low basal levels, rendering supraphysiological caspase-9 activation a tractable target for therapeutic interventions. Strategies for selective inhibition of caspase-9 include dominant negative caspase-9 mutants and pharmacological inhibitors derived from the XIAP protein, whose Bir3 domain is an endogenous highly selective caspase-9 inhibitor. However, the mechanistic implications of caspase-9 expression and activation remain indeterminate in many pathologies. By assembling clinical reports of caspase-9 genetics, signaling and cellular localization in human tissues, this review identifies gaps between experimental and clinical studies on caspase-9, and presents opportunities for further investigations to examine the consequences of caspase activity in human disease.

Abstract
INTRODUCTION Apoptosis deregulation have been associated to tumorigenesis process and was highlighted as a prominent hallmark of cancer. Several mutations have been reported in several forms of Blood cancer. However, it has never been investigated in familial aggregations of hematological malignancies. METHODS In this study, we performed a mutational analysis by sequencing the entire coding regions in four key apoptotic genes FAS, FASLG, CASP8 and CASP10 in 92 independent families belonging to French and Tunisian populations and diagnosed with several forms of familial hematological malignancies. RESULTS We report 15 genetic variations among which 7 were previously reported in several form of cancers and have a potential effect on gene expression. Particularly, the CASP8 variants p.Asp302His and p.Lys337Lys were detected in 15% and 10% of our group of patients respectively and were previously reported in association to breast cancer and to breast cancer susceptibility. DISCUSSION In this study, we do not report the underlining deleterious mutations in familial hematological malignancies, but we describe some variants with potential risk of developing blood cancer. To gain further insights on the association between apoptosis pathway deregulation and familial hematological malignancies, more apoptotic genes should be investigated.

Abstract
Caspase-8 plays is an essential enzyme in apoptosis pathway. Several investigation have been done to identify the relation between CASP8 polymorphisms and different human cancers, but, the findings are still debated. The aim of the current investigation is to assess if CASP8 rs3834129 (-652 6N insertion/deletion), rs1045485 G > C, rs3769818 G > A, rs6723097 A > C, rs3769821 T > C, rs13113 T > A, rs3769825 G > A, rs2293554 A > C, and rs10931936 C > T polymorphisms are linked to susceptibility of cancer. Our team has extracted the eligible studies up to July 4, 2019, from different sources. Pooled odds ratios (ORs) with corresponding 95% confidence intervals (CIs) were estimated to quantitatively evaluate the association between CASP8 polymorphisms and cancer susceptibility. Our results showed that the rs3834129 and rs1045485 polymorphisms meaningfully reduced the risk of cancer, while the rs3769818, rs3769821 and rs3769825 polymorphisms considerably increased cancer susceptibility. No association of rs6723097, rs13113, rs2293554 and rs10931936 polymorphisms was observed with cancer susceptibility. The CASP8 rs3834129 polymorphism reduced the risk of gastrointestinal, digestive tract, colorectal, breast and lung cancers. Furthermore, the cancer risk was decreased in Asian and Caucasian populations as well as population- and hospital-based studies due to this polymorphism. There was not any relation between this gene polymorphism and the risk of prostate and cervical cancer development. Regarding the CASP8 rs1045485 polymorphism, the reduced breast cancer risk along with the risk of cancer in Caucasians, population- and hospital-based studies were observed.

Abstract
Rotator cuff tendinopathy (RCT), anterior cruciate ligament (ACL) ruptures, and carpal tunnel syndrome (CTS), are examples of chronic (RCT and CTS) and acute (ACL ruptures) musculoskeletal soft tissue injuries. These injuries are multifactorial in nature, with several identified intrinsic and extrinsic risk factors. Previous studies have implicated specific sequence variants within genes encoding structural and regulatory components of the extracellular matrix of tendons and/ligaments to predispose individuals to these injuries. An example, includes the association of sequence variants within the apoptotic regulatory gene, caspase-8 (CASP8) with other musculoskeletal injury phenotypes, such as Achilles tendinopathy. The primary aim of this study was, therefore, to investigate previously implicated DNA sequence variants within CASP8: rs3834129 (ins/del) and rs1045485 (G/C), and the rs13113 (T/A) identified using a whole exome sequencing approach, with risk of musculoskeletal injury phenotypes (RCT, ACL ruptures, and CTS) in three independent studies. In addition, the aim was to implicate a CASP8 genomic interval in the modulation of risk of RCT, ACL ruptures, or CTS. It was found that the AA genotype of CASP8 rs13113 (T/A) was independently associated with increased risk for CTS. In addition, it was found that the del-C haplotype (rs3834129-rs1045485) was significantly associated with non-contact ACL ruptures, which is in alignment with previous research findings. Collectively, the results of this study implicate the apoptosis pathway as biologically significant in the underlying pathogenesis of musculoskeletal injury phenotypes. These findings should be repeated in larger sample cohorts and across different populations. © 2019 Orthopaedic Research Society. Published by Wiley Periodicals, Inc. J Orthop Res 38:680-688, 2020.

Abstract
Several studies inspected the relationship between caspase-3 (CASP3) polymorphisms and the risk of several human cancers, but the findings remain controversial. We conducted a meta-analysis aiming to inspect the association between CASP3 rs1049216 T>C, rs12108497 C>T, rs4647603 G>A, rs4647602 C>A, rs6948 T>G, rs2705897 A>C, and rs113420705 G>A polymorphisms and cancer risk. Eligible studies were recognized by searching the Web of Science, PubMed, Scopus, and Google Scholar databases. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were estimated to quantitatively evaluate the association between each polymorphism of CASP3 and cancer risk. The rs4647603 variant significantly increased the risk of cancer in an overdominant (OR, 1.44; 95% CI, 1.03-2.01; P = 0.03; AG vs AA+GG) inheritance model. Regarding the rs4647602 variant, the findings revealed that this variant was associated with protection against cancer in homozygous codominant (OR, 0.67; 95% CI, 0.56-0.80; P < 0.00001; AA vs CC), dominant (OR, 0.84; 95% CI, 0.73-0.96; P = 0.009; AC+AA vs CC), recessive (OR, 0.70; 95% CI, 0.61-0.79; P < 0.00001; AA vs AC+CC), and allele (OR, 0.81; 95% CI, 0.75-0.88; P = 0.00001; A vs C) models. The findings suggested that the rs2705897 variant significantly decreased the risk of cancer in heterozygous codominant (OR, 0.80; 95% CI, 0.67-0.94; P = 0.009; AC vs AA), dominant (OR, 0.81; 95% CI, 0.69-0.95; P = 0.009; AC+CC vs AA), overdominant (OR, 0.80; 95% CI, 0.68-0.95; P = 0.01; AC vs CC+AA), and allele (OR, 0.85; 95% CI, 0.74-0.97; P = 0.02; C vs A) models. The results did not support an association between CASP3 rs1049216 and rs6948 polymorphisms and cancer risk. In summary, the findings of this meta-analysis support an association between CASP3 polymorphisms and cancer risk. Larger and well-designed studies are desired to evaluate these associations in detail.

Influence of Caspase-9 polymorphisms on the development of Chronic Myeloid Leukemia- A case-control study. Gene 2019; 721S:100002. [PMID: 34530993 PMCID: PMC7286081 DOI: 10.1016/j.gene.2018.100002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2018] [Accepted: 11/30/2018] [Indexed: 11/22/2022]
Abstract
Introduction Chronic Myeloid Leukemia (CML) is a myeloproliferative disorder, characterized by the overproduction of myeloid cells in all stages of maturation. It is usually defined by three sequential stages (Chronic, Accelerated and Blast-crisis) where the transition from chronic to accelerated to blast phases is presumed to occur due to secondary genetic changes, viz. accumulation of mutations, activation of downstream pathways and failure of apoptosis. Caspase 9 is the initiator caspase involved in mitochondrial-mediated apoptotic pathway. Polymorphisms in the promoter (−1263 A>G, -712C>T, -293 del) and coding (Ex5 +32G>A) regions of CASP9 gene are found to influence the expression levels by either impairing the activation or loss of expression of CASP9 or insufficient formation of apoptosome. Methods The present case-control study was carried out on 999 individuals, comprised of 485CML cases reported at Nizams Institute of Medical Sciences (NIMS), Hyderabad and 514 age and gender-matched healthy individuals from local population. DNA was isolated by non-enzymatic/salting-out method and was genotyped using RFLP technique. Results It was observed that the presence of G allele of CASP9 -1263A>G polymorphism enhanced the risk for CML while CASP9 -712C>T and CASP9 -293del SNPs conferred protection against development of CML. Haplotype analysis of promoter and exonic polymorphisms had revealed increased risk associated with two haplotypes G_C_del (+)_G (OR-1.61, 95% CI-0.97-2.65, p-0.06#) and G_C_del (–)_G (OR-2.09, 95% CI-0.94-4.66, p-0.07#) suggesting the role of G allele of CASP9 -1263A>G in conferring risk independent of other SNPs. Pairwise LD analysis performed for all the four SNPs revealed the presence of LD among the SNPs. Conclusion The results of the present study therefore concludes the role of CASP9 -1263A>G polymorphism in increasing the risk for the development and progression while CASP9 -712C>T and CASP9 -293del SNPs conferred protection and CASP9 Ex5 +32G>A was involved in conferring resistance which could be in combination with other SNPs or factors affecting them.

Abstract
OBJECTIVE In the present study, we investigated the relationship between the single-nucleotide polymorphism (SNP) of caspase-3 rs1049216 (C > T), a miRNA target site, and the risk and progression of cervical cancer. MATERIALS AND METHODS Using polymerase chain reaction-restriction fragment length polymorphism, we evaluated the genotype and distribution of caspase-3 rs1049216 in 515 patients with cervical squamous cell cancer and 415 controls. In additional experiments, we transfected luciferase reporter plasmids carrying T or C allele and/or miRNA mimics into the human cervical cell lines (HeLa and C-33A) to analyze its roles in the regulation of caspase-3 expression. By immunohistochemistry, the protein level of caspase-3 expression was examined in tumor tissues from 515 patients with cervical squamous cell cancer. RESULTS We found that the TT genotype of caspase-3 rs1049216 conferred a significantly decreased risk of cervical cancer (adjusted odds ratio, 0.35; 95% confidence interval, 0.154-0.581) and may be associated with the progression of this cancer. Although the expression of caspase-3 in the TT genotype was higher than that in CC/CT genotype in peripheral blood mononuclear cells and tumor tissues. Additional luciferase analysis showed that the rs1049216 variant T allele was associated with significantly higher luciferase activity, compared with the C allele in the transfected cells, and when cotransfected with miRNAs, miRNA-181a could downregulate the luciferase activity in the cells that transfected the construct containing C allele, compared with T allele, which had not happened in the presence of other miRNAs selected. CONCLUSIONS These data indicate that through upregulating the expression of caspase-3, the TT genotype of caspase-3 rs1049216 can be associated with not only the risk of cervical cancer but also the progression of this cancer.

Abstract
Multiple myeloma (MM) is an incurable malignancy of mature B-lymphoid cells, and its pathogenesis is only partially understood. Previous studies have demonstrated that a number of Non-Hodgkin Lymphoma (NHL) associated genes also show susceptibility to MM, suggesting malignancies originating from B cells may share similar genetic susceptibility. Several recent large-scale genome-wide association studies (GWAS) have identified HLA-I, HLA-II, CXCR5, ETS1, LPP and NCOA1 genes as genetic risk factors associated with NHL, and this study aimed to investigate whether these genes polymorphisms confer susceptibility with MM in the Chinese Han population. In 827 MM cases and 709 healthy controls of Chinese Han, seven single nucleotide polymorphisms (SNPs) in the HLA–I region (rs6457327), the HLA–II region (rs2647012 and rs7755224), the CXCR5 gene (rs4938573), the ETS1 gene (rs4937362), the LPP gene (rs6444305), and the NCOA1 region (rs79480871) were genotyped using the Sequenom platform. Our study indicated that genotype and allele frequencies of rs79480871 showed strong associations with MM patients (pa = 3.5×10−4 and pa = 1.5×10−4), and the rs6457327 genotype was more readily associated with MM patients than with controls (pa = 4.9×10−3). This study was the first to reveal the correlation between NCOA1 gene polymorphisms and MM patients, indicating that NCOA1 might be a novel susceptibility gene for MM patients in the Chinese Han population.

Abstract
We studied 140 families with two or more lymphoid cancers, including non-Hodgkin lymphoma (NHL), Hodgkin lymphoma (HL), chronic lymphocytic leukemia (CLL), and multiple myeloma (MM), for deviation from the population age of onset and lymphoid cancer co-occurrence patterns. Median familial NHL, HL, CLL and MM ages of onset are substantially earlier than comparable population data. NHL, HL and CLL (but not MM) also show earlier age of onset in later generations, known as anticipation. The co-occurrence of lymphoid cancers is significantly different from that expected based on population frequencies (p < .0001), and the pattern differs more in families with more affected members (p < .0001), suggesting specific lymphoid cancer combinations have a shared genetic basis. These families provide evidence for inherited factors that increase the risk of multiple lymphoid cancers. This study was approved by the BC Cancer Agency - University of British Columbia Clinical Research Ethics Board.

Caspase-8 polymorphisms result in reduced Alemtuzumab-induced T-cell apoptosis and worse survival after transplantation. Bone Marrow Transplant 2014; 50:237-43.

Abstract
Allo-SCT using unrelated donors is a curative treatment for patients with hematological disorders. The best donor is one matched for 10/10 HLA alleles, however studies have shown an additional survival benefit when considering other genetic factors. It has been shown that a six-nucleotide insertion/deletion polymorphism in the CASP8 gene promoter results in reduced susceptibility of T lymphocytes to undergo apoptosis. In 186 SCT recipients, we found a significantly better OS in those who received a transplant from a WT/WT donor compared with donors with a deletion (3 years: 52 vs 34%; P=0.03; multivariate analysis; RR 0.61; 95% CI 0.38-0.98, P=0.04). This was more marked when both the patient and the donor had a deletion (3 years OS: 62% compared with 36%, P=0.01). As the majority of these patients received Alemtuzumab during conditioning, we went on to analyze the in vitro effect of the polymorphism on Alemtuzumab-induced apoptosis. We showed statistically significantly higher percentages of apoptotic naïve CD4 (P<0.0005) and CD8 (P<0.0005) T cells in WT/WT donors in comparison with donors with a deletion. These data imply an unrecognized role for the CASP8 promoter polymorphism on survival following unrelated SCT particularly in the context of T-cell depletion with Alemtuzumab.

Abstract
It has been suggested that mitochondrial dysfunction and DNA damage are involved in lymphomagenesis. Increased copy number of mitochondrial DNA (mtDNA) as a compensatory mechanism of mitochondrial dysfunction previously has been associated with B-cell lymphomas, in particular chronic lymphocytic leukemia (CLL). However, current evidence is limited and based on a relatively small number of cases. Using a nested case-control study, we extended these findings with a focus on subtype-specific analyses. Relative mtDNA copy number was measured in the buffy coat of prospectively collected blood of 469 lymphoma cases and 469 matched controls. The association between mtDNA copy number and the risk of developing lymphoma and histologic subtypes was examined using logistic regression models. We found no overall association between mtDNA and risk of lymphoma. Subtype analyses revealed significant increased risks of CLL (n = 102) with increasing mtDNA copy number (odds ratio = 1.34, 1.44, and 1.80 for quartiles 2-4, respectively; P trend = .001). mtDNA copy number was not associated with follow-up time, suggesting that this observation is not strongly influenced by indolent disease status. This study substantially strengthens the evidence that mtDNA copy number is related to risk of CLL and supports the importance of mitochondrial dysfunction as a possible mechanistic pathway in CLL ontogenesis.

Association of caspase9 promoter polymorphisms with the susceptibility of AML in south Indian subjects. Tumour Biol 2014; 35:8813-22.

Abstract
Abnormal apoptosis is one of the hallmarks of cancers including acute myeloid leukemia (AML), as it plays a pivotal role in precisely maintaining self-renewal, proliferation, and differentiation properties of hematopoietic stem cells (HSCs). Caspase9 (CASP9), an initiator caspase activated by mitochondrial-mediated apoptotic pathway (intrinsic pathway), triggers cascade of effector caspases and executes apoptosis. Functional SNPs in CASP9 might influence the gene expression leading to altered apoptosis which confer the risk to AML. To test this hypothesis, we have analyzed four CASP9 gene polymorphisms [CASP9 - 1263A > G (rs4645978), CASP9 - 712C > T (rs4645981), CASP9 - 293_275del CGTGAGGTC AGTGCGGGGA (-293del) (rs4645982), and CASP9 Ex5 + 32G > A (rs1052576)] in 180 AML cases and 304 age- and sex-matched healthy controls. We performed various statistical analyses to determine the potential interactions between these SNPs and AML. The study revealed that presence of G allele at CASP9 - 1263 position elevates the risk of AML 1.53-fold and CT/TT genotype at CASP9 - 712 position by 2.60-fold under dominant model of inheritance. Two CASP9 haplotypes, G-del(+)-C-A and G-del(+)-T-A, were found to be significantly associated with increased AML risk by 2.19- (95 % confidence interval (CI), 1.09-4.39; p = 0.028) and 11.75-fold (95 % CI, 1.01-136.57; p = 0.05), respectively. Further, multidimensionality reduction (MDR) analysis had revealed single locus CASP9 - 712C > T SNP and four loci CASP9 - 1263A > G, CASP9 - 293del, CASP9 - 712C > T, and CASP9 Ex5 + 32G > A SNPs as highest predicting models for AML development. Our results revealed a significant association of two SNPs in CASP9 (-1263A > G and -712C > T) and two haplotypes of the four SNP combinations with AML susceptibility.

Abstract
PURPOSE Genetic polymorphisms in one-carbon metabolizing pathway genes have been associated with risk of malignant lymphoma. However, the results have been inconsistent. The objectives of this study were to examine the potential relationship between gene-nutrient interactions and the risk of non-Hodgkin lymphoma (NHL). METHODS We examined 25 polymorphisms in 16 one-carbon metabolism genes for their main effect and gene-nutrient interactions in relation to NHL risk among 518 incident cases and 597 population-based controls of Connecticut women enrolled between 1996 and 2000. RESULTS A significantly reduced risk of NHL was associated with the homozygous TT genotype in CBS (rs234706, Ex9+33C>T) (OR = 0.51, 95 % CI 0.31-0.84), the homozygous CC genotype in MBD2 (rs603097, -2176C>T) (OR = 0.37, 95 % CI 0.17-0.79), the heterozygote AG genotype in FTHFD (rs1127717, Ex21+31A>G) (OR = 0.73, 95 % CI 0.55-0.98), and a borderline significantly reduced risk of NHL was observed for the homozygous CC genotype in MTRR (rs161870, Ex5+136T>C) (OR = 0.23, 95 % CI 0.05-1.04). The reduced risk of NHL associated with these genotypes was predominately in those with higher dietary vitamin B6 and methionine intakes, as well as with higher dietary folate intake although results were less stable. A borderline significantly increased risk of NHL was also observed for CBS (rs1801181, Ex13+41C>T), FTHFD (rs2305230, Ex10-40G>T), SHMT1 (rs1979277, Ex12+138C>T), and SHMT1 (rs1979276, Ex12+236T>C), and these associations appeared to be contingent on dietary nutrient intakes. CONCLUSION Our results suggest that variation in several one-carbon metabolizing pathway genes may influence the risk of NHL through gene-nutrient interactions involving dietary nutrient intakes.

Abstract
The initiators caspase-9 (CASP9) and caspase-10 (CASP10) are two key controllers of apoptosis and play important roles in carcinogenesis. This study aims to explore the association between CASPs gene polymorphisms and colorectal cancer (CRC) susceptibility in a population-based study. A two-stage designed population-based case-control study was carried out, including a testing set with 300 cases and 296 controls and a validation set with 206 cases and 845 controls. A total of eight tag selected single nucleotide polymorphisms (SNPs) in CASP9 and CASP10 were chosen based on HapMap and the National Center of Biotechnology Information (NCBI) datasets and genotyped by restriction fragment length polymorphism (RFLP) assay. Multivariate logistic regression models were applied to evaluate the association of SNPs with CRC risk. In the first stage, from eight tag SNPs, three polymorphisms rs4646077 (odds ratio (OR)(AA+AG): 0.654, 95% confidence interval (CI): 0.406-1.055; P=0.082), rs4233532 (OR(CC): 1.667, 95% CI: 0.967-2.876; OR(CT): 1.435, 95% CI: 0.998-2.063; P=0.077), and rs2881930 (OR(CC): 0.263, 95% CI: 0.095-0.728, P=0.036) showed possible association with CRC risk. However, none of the three SNPs, rs4646077 (OR(AA+AG): 1.233, 95% CI: 0.903-1.683), rs4233532 (OR(CC): 0.892, 95% CI: 0.640-1.243; OR(CT): 1.134, 95% CI: 0.897-1.433), and rs2881930 (OR(CC): 1.096, 95% CI: 0.620-1.938; OR(CT): 1.009, 95% CI: 0.801-1.271), remained significant with CRC risk in the validation set, even after stratification for different tumor locations (colon or rectum). In addition, never tea drinking was associated with a significantly increased risk of CRC in testing set together with validation set (OR: 1.755, 95% CI: 1.319-2.334). Our results found that polymorphisms of CASP9 and CASP10 genes may not contribute to CRC risk in Chinese population and thereby the large-scale case-control studies might be in consideration. In addition, tea drinking was a protective factor for CRC.

Abstract
PURPOSE Caspase 8 (CASP8) plays a critical role in the apoptotic pathway and aberrant regulation of this pathway causes many diseases including cancers. Genetic variants rs3834129 (CTTACT/-) and rs3769821 (T/C) in the promoter region of the CASP8 gene were documented to be associated with multiple solid cancers and non-Hodgkin's lymphoma (NHL), respectively, despite of some controversies. We aimed to discern potential association of these two variants and rs113686495 (CTGTCATT/-), as well as CASP8 mRNA and protein expression levels with colorectal cancer (CRC) in Han Chinese. METHODS We genotyped CASP8 genetic variants in 305 CRC patients and 342 healthy individuals from Kunming, Southwest China. Expression levels of CASP8 mRNA and protein were quantified in paired cancerous and paracancerous normal tissues by using real-time quantitative PCR and western blot, respectively. We compared the frequencies of alleles, genotypes, and haplotypes between the cases and controls. Correlation of CASP8 mRNA and protein expression levels in paired cancerous and paracancerous normal tissues from patients with different genotypes and clinical expression were also evaluated. RESULTS There was no association of the CASP8 genetic variants with CRC in our case-control study. The CASP8 gene mRNA expression levels in cancerous and paracancerous normal tissues were similar and there was no significant difference between subjects with different genotypes and clinical features. However, we found that CASP8 protein level was significantly lower in cancerous tissues than in paired paracancerous normal tissues. CONCLUSIONS Our results suggest that the three CASP8 genetic variants may not be associated with CRC risk in Han Chinese from southwest China. Aberrant CASP8 protein expression may play a role in the pathogenesis of CRC.

Abstract
Genome-wide association studies (GWAS) have previously identified 13 loci associated with risk of chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL). To identify additional CLL susceptibility loci, we conducted the largest meta-analysis for CLL thus far, including four GWAS with a total of 3,100 individuals with CLL (cases) and 7,667 controls. In the meta-analysis, we identified ten independent associated SNPs in nine new loci at 10q23.31 (ACTA2 or FAS (ACTA2/FAS), P=1.22×10(-14)), 18q21.33 (BCL2, P=7.76×10(-11)), 11p15.5 (C11orf21, P=2.15×10(-10)), 4q25 (LEF1, P=4.24×10(-10)), 2q33.1 (CASP10 or CASP8 (CASP10/CASP8), P=2.50×10(-9)), 9p21.3 (CDKN2B-AS1, P=1.27×10(-8)), 18q21.32 (PMAIP1, P=2.51×10(-8)), 15q15.1 (BMF, P=2.71×10(-10)) and 2p22.2 (QPCT, P=1.68×10(-8)), as well as an independent signal at an established locus (2q13, ACOXL, P=2.08×10(-18)). We also found evidence for two additional promising loci below genome-wide significance at 8q22.3 (ODF1, P=5.40×10(-8)) and 5p15.33 (TERT, P=1.92×10(-7)). Although further studies are required, the proximity of several of these loci to genes involved in apoptosis suggests a plausible underlying biological mechanism.

Abstract
Impaired function of Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway genes leads to immunodeficiency and various hematopoietic disorders. We evaluated the association between genetic polymorphisms (SNPs) in 12 JAK/STAT pathway genes (JAK3, STAT1, STAT2, STAT3, STAT4, STAT5a, STAT5b, STAT6, SCOS1, SCOS2, SCOS3, and SCOS4) and NHL risk in a population-based case-control study of Connecticut women. We identified three SNPs in STAT3 (rs12949918 and rs6503695) and STAT4 (rs932169) associated with NHL risk after adjustment for multiple comparison. Our results suggest that genetic variation in JAK/STAT pathway genes may play a role in lymphomagenesis and warrants further investigation.

Abstract
Caspases are a family of endoproteases that provide critical links in cell regulatory networks controlling inflammation and cell death. The activation of these enzymes is tightly controlled by their production as inactive zymogens that gain catalytic activity following signaling events promoting their aggregation into dimers or macromolecular complexes. Activation of apoptotic caspases results in inactivation or activation of substrates, and the generation of a cascade of signaling events permitting the controlled demolition of cellular components. Activation of inflammatory caspases results in the production of active proinflammatory cytokines and the promotion of innate immune responses to various internal and external insults. Dysregulation of caspases underlies human diseases including cancer and inflammatory disorders, and major efforts to design better therapies for these diseases seek to understand how these enzymes work and how they can be controlled.

Abstract
Caspases are important regulators and executioners in the apoptosis pathways and play crucial roles in carcinogenesis. We tested the hypothesis that functional variants of CASP genes are associated with risk of squamous cell carcinoma of the head and neck (SCCHN) and second primary malignancy (SPM). We genotyped 7 selected, potentially functional single nucleotide polymorphisms (SNPs) located in the microRNA binding sites of the 3' untranslational region (UTR; 2 in CASP3, 1 in CASP6, and 4 in CASP7) and evaluated their associations first with risk of SCCHN in 1066 patients with SCCHN and 1074 cancer-free control subjects and then with SPM in 846 patients in the same non-Hispanic white study population. We found that compared with the CASP3 TT genotype of rs1049253, the variant TC/CC genotypes were associated with significantly increased risk of SCCHN (adjusted odds ratio=1.29 and 95% confidence interval=1.07-1.56) and SPM (adjusted hazard ratio=1.79 and 95% CI=1.02-3.16) and worse SPM-free survival (log-rank P = 0.020), but no associations were found for the other 6 SNPs. We then performed additional experiments to seek functional relevance of the rs1049253 SNP. First, the luciferase activity and miR-885-5p mimic transfection tests suggested that CASP3 was the target of miR-885-5p and that rs1049253T>C resulted in altered regulation of the CASP3 expression. Second, the rs1049253 CC genotype was associated with reduced levels of CASP3 mRNA in peripheral blood mononuclear cells from 118 SCCHN patients and 103 cancer-free control subjects and lower levels of CASP3 protein expression in 11 head and neck cancer cell lines, compared with the TT genotype. Taken together, our data suggest that the miR-885-5p binding site rs1049253T>C SNP in the 3'-UTR of CASP3 modulates CASP3 expression at both mRNA and protein levels and thus contributes to SCCHN susceptibility.

Abstract
Failure of apoptosis is one of the hallmarks of cancer. As an execution-phase caspase, caspase-9 plays a crucial role during apoptosis. To examine whether the Ex5+32 G>A (rs1052576) polymorphism in the CASP-9 gene alters cancer risk, we conducted a comprehensive meta-analysis of 7 case-control studies consisting of a total of 1668 cancer cases and 2294 healthy controls. All studies considered, A allele and A allele carriers of Ex5+32 G>A in the CASP-9 gene had significant associations with cancer risk (OR=0.72, 95% CI, 0.58–0.89, P= 0.003; OR= 0.76, 95% CI, 0.63–0.92, P= 0.004; respectively). In the subgroup analysis, we found that the A allele of Ex5+32 G>A was a protective factor for cancer risk in Chinese and American populations (OR=0.60, 95% CI, 0.44–0.81, P<0.001; OR= 0.80, 95% CI, 0.69–0.94, P= 0.005; respectively). Similarly, we also found positive associations between A allele carriers of Ex5+32 G>A and cancer risk in Chinese and American populations (OR=0.63, 95% CI, 0.44–0.90, P= 0.01; OR= 0.78, 95% CI, 0.62–0.98, P=0.03; respectively). In addition, we identified that A allele and A allele carriers of Ex5+32 G>A may decrease the risk of cancer in the Asian population (OR=0.60, 95% CI, 0.44–0.81, P<0.001; OR= 0.63, 95% CI, 0.44–0.90, P= 0.01; respectively). In conclusion, this meta-analysis demonstrated that A allele and A allele carriers of the Ex5+32 G>A polymorphism in the CASP-9 gene may be protective factors for cancer risk.

Abstract
Caspases (CASPs), play a crucial role in the development and progression of cancer. We evaluated the association between two polymorphisms (rs4645978 and rs4645981) of the CASP9 gene and the risk of breast cancer (BC). Genotypes and allelic frequencies for the two polymorphisms were determined in 261 patients with breast cancer and 480 healthy controls. Polymerase chain reaction-restriction fragment length polymorphisms were used, and statistical significance was determined by the χ(2) test. Carriers of the rs4645978G allele (AG and GG genotypes) were at higher risk for BC than individuals with other genotypes (odds ratio (OR) 1.59, 95% confidence interval (CI) 1.07-2.37, P = 0.022). The rs4645978GG genotype, in particular, was associated with the highest risk for BC development (OR 2.25, 95% CI 1.45-3.49, P = 0.0003). Similarly, individuals with at least one rs4645981T allele were at a significantly increased risk of developing BC compared with those harboring the CC genotype (OR 2.75, 95% CI 1.99-3.78, P < 0.0001), and the risk of BC increased with increasing numbers of rs4645981T alleles (OR 2.66, 95% CI 1.91-3.69, P < 0.0001 for the CT genotype; OR 3.95, 95% CI 1.58-9.88, P = 0.004 for the TT genotype). The CASP9 promoter polymorphisms rs4645978 and rs4645981 are associated with BC susceptibility and suggest that CASP9 transcriptional regulation is an important factor during BC development.

Abstract
Apoptosis is a distinct mode of cell death that is responsible for the deletion of cells in tumors and in normal tissues. We pursued a pathway-based approach to investigate the association of potentially functional genetic polymorphisms of the corresponding genes with the outcomes of platinum-based chemotherapy in advanced non-small-cell lung cancer (NSCLC). A MALDI-TOF mass spectrometer was used for genotyping 10 polymorphisms of eight apoptosis-related genes, including BCL2 rs1801018, rs1564483, rs2279115, BAX rs4645878, caspase (CASP3) rs6948, CASP8 rs3834129, CASP10 rs13006529, rs3900115, tumor necrosis factor α (TNFα) rs1800629, and macrophage migration inhibitory factor (MIF) rs755622. The associations between these single nucleotide polymorphisms and the outcomes of 445 advanced NSCLC patients treated with platinum-based chemotherapy were evaluated. The CASP3 rs6948 polymorphism was most significantly associated with hematologic toxicity in a dose-dependent manner. The incidence of severe hematologic toxicity was significantly lower in C allele carriers (P = 0.005; odds ratio = 0.524; 95% confidence interval = 0.333-0.824) and still significant after a Bonferroni correction. The function of this single nucleotide polymorphism in gene expression was also investigated. Quantitative PCR showed that individuals with the C allele had lower levels of CASP3 transcripts in peripheral blood lymphocytes. Luciferase reporter assays showed that the minor C allele significantly decreased the reporter gene expression level. In addition, the TNFα rs1800629 mutant allele significantly elevated gastrointestinal toxicity (P = 0.020; odds ratio = 3.020; 95% confidence interval = 1.188-7.676), when compared to the wild-type homozygote. No other association was found. In conclusion, for the first time, our study suggests that CASP3 rs6948 might influence CASP3 expression and be associated with severe hematologic toxicity risk.

Abstract
Background Caspases are important regulators and executioners in apoptosis pathway and have been defined as either tumor suppressors or oncogenes. Polymorphisms in promoter and exon of caspase 9 were shown to confer genetic susceptibility to multiple cancers, but the results were inconsistent. To accomplish a more precise estimation of the relationship, a meta-analysis was performed. Methodology/Principal Findings We assessed published studies of the association between caspase 9 polymorphisms and cancer risk from nine studies with 5,528 subjects for rs4645978, six studies with 2,403 subjects for rs105276 and two studies for rs4645981. Overall meta-analysis indicated that no evidence of an association between rs4645978 and cancers was found. Through the stratified analysis, statistically significant reduced cancer risks were observed among Caucasians (AG vs AA: OR = 0.81, 95% CI = 0.66–0.99, Pheterogeneity = 0.150 and the dominant model: OR = 0.86, 95% CI = 0.75–0.99, Pheterogeneity = 0.290) and prostate cancer. As for rs105276, Ex5+32G>A polymorphism was found with protective effect in overall meta-analysis (AA vs GG: OR = 0.75, 95% CI = 0.60–0.92, Pheterogeneity = 0.887; A vs G: OR = 0.85, 95% CI = 0.77–0.95, Pheterogeneity = 0.739 and the recessive model: OR = 0.68, 95% CI = 0.56–0.82, Pheterogeneity = 0.309) and Asians group. While for rs4645981, a statistically significant increase in risk of lung cancer was shown in Asians (T vs C: OR = 1.23, 95% CI = 1.07–1.42, Pheterogeneity = 0.399 and the dominant model: OR = 1.22, 95% CI = 1.04–1.43, Pheterogeneity = 0.660). Conclusions/Significance Our meta-analysis suggests that the caspase 9 rs4645978 most likely contributes to decreased susceptibility to cancer in Caucasians and prostate cancer. The A allele of rs105276 might be a protective factor for cancer, especially for Asians. However, it seems that rs4645981 confers increased susceptibility to lung cancer in Asians.

Abstract
INTRODUCTION: Non-Hodgkin Lymphoma (NHL) is a heterogeneous group of malignancies with over thirty different subtypes. Follicular lymphoma (FL) is the most common form of indolent NHL and the second most common form of NHL overall. It has morphologic, immunophenotypic and clinical features significantly different from other subtypes. Considerable effort has been devoted to the identification of risk factors for etiology and prognosis of FL. These risk factors may advance our understanding of the biology of FL and have an impact on clinical practice. AREAS COVERED: The epidemiology of NHL and FL is briefly reviewed. For FL etiology and prognosis separately, we review clinical, environmental and molecular (including genetic, genomic, epigenetic and others) risk factors suggested in the literature. EXPERT OPINION: A large number of potential risk factors have been suggested in recent studies. However, there is a lack of consensus, and many of the suggested risk factors have not been rigorously validated in independent studies. There is a need for large-scale, prospective studies to consolidate existing findings and discover new risk factors. Some of the identified risk factors are successful at the population level. More effective individual-level risk factors and models remain to be identified.

Interaction among apoptosis-associated sequence variants and joint effects on aggressive prostate cancer. BMC Med Genomics 2012; 5:11.

Abstract
Background Molecular and epidemiological evidence demonstrate that altered gene expression and single nucleotide polymorphisms in the apoptotic pathway are linked to many cancers. Yet, few studies emphasize the interaction of variant apoptotic genes and their joint modifying effects on prostate cancer (PCA) outcomes. An exhaustive assessment of all the possible two-, three- and four-way gene-gene interactions is computationally burdensome. This statistical conundrum stems from the prohibitive amount of data needed to account for multiple hypothesis testing. Methods To address this issue, we systematically prioritized and evaluated individual effects and complex interactions among 172 apoptotic SNPs in relation to PCA risk and aggressive disease (i.e., Gleason score ≥ 7 and tumor stages III/IV). Single and joint modifying effects on PCA outcomes among European-American men were analyzed using statistical epistasis networks coupled with multi-factor dimensionality reduction (SEN-guided MDR). The case-control study design included 1,175 incident PCA cases and 1,111 controls from the prostate, lung, colo-rectal, and ovarian (PLCO) cancer screening trial. Moreover, a subset analysis of PCA cases consisted of 688 aggressive and 488 non-aggressive PCA cases. SNP profiles were obtained using the NCI Cancer Genetic Markers of Susceptibility (CGEMS) data portal. Main effects were assessed using logistic regression (LR) models. Prior to modeling interactions, SEN was used to pre-process our genetic data. SEN used network science to reduce our analysis from > 36 million to < 13,000 SNP interactions. Interactions were visualized, evaluated, and validated using entropy-based MDR. All parametric and non-parametric models were adjusted for age, family history of PCA, and multiple hypothesis testing. Results Following LR modeling, eleven and thirteen sequence variants were associated with PCA risk and aggressive disease, respectively. However, none of these markers remained significant after we adjusted for multiple comparisons. Nevertheless, we detected a modest synergistic interaction between AKT3 rs2125230-PRKCQ rs571715 and disease aggressiveness using SEN-guided MDR (p = 0.011). Conclusions In summary, entropy-based SEN-guided MDR facilitated the logical prioritization and evaluation of apoptotic SNPs in relation to aggressive PCA. The suggestive interaction between AKT3-PRKCQ and aggressive PCA requires further validation using independent observational studies.

Abstract
Caspase-3 (CASP3) is the main executioner of apoptosis, mediating both extrinsic and intrinsic cell death signaling pathways, and is involved in tumor behaviors. In this study, we investigated the association of two regulatory variants in CASP3 and the risk of esophageal squamous cell carcinoma (ESCC) in 1026 cases and 1270 healthy controls. Odds ratios (OR) and 95% confidence intervals (CI) were computed by logistic regression. The function of the CASP3 829 A>C polymorphism was examined by luciferase reporter assay and real-time PCR. A significant increased risk of ESCC was found for the CASP3 829 AC and CC genotypes with OR (95% CI), 1.53 (1.26-1.89) and 1.42 (1.11-1.82), respectively. When stratified by age and gender, the risk of ESCC was more significant in younger (≤57 years) and male individuals. No significantly changed risk of ESCC was related to 20541 C>T variant. Luciferase reporter assay showed 829 A>C variant dramatically reduced the transcriptional activity of luciferase reporter gene by over 95% in both KYSE30 and KYSE450 esophageal cancer cells. Remarkably, the transcriptional activity of the 829C-containing construct was much lower than the activity of the pGL3-basic construct, with over 85% reduction in both cell lines. Real-time PCR analyses showed that 829 AA genotype carriers had significantly higher RNA levels (0.015 ± 0.00216, n = 24) than the 829 AC genotype carriers (0.00969 ± 0.00136, n = 36), and 829 CC genotype carriers (0.00663 ± 0.00097, n = 20). These findings suggest that CASP3 829 A>C polymorphism may highly affect the function of caspase-3 and play an important role in the development of ESCC in Chinese populations.

Abstract
INTRODUCTION: Despite decades of intensive research, Non-Hodgkin Lymphoma (NHL) remains poorly understood and is largely incurable. NHL is a heterogeneous group of malignancies with multiple subtypes, each of which has distinct morphologic, immunophenotypic, and clinical features. Identifying the risk factors for NHL may improve our understanding of the underlying biological mechanisms and have an impact on clinical practice. AREAS COVERED: This article provides a review of several aspects of NHL, including epidemiology and subtype classification, clinical, environmental, genetic, and genomic risk factors identified for etiology and prognosis, and available statistical and bioinformatics tools for identification of genetic and genomic risk factors from the analysis of high-throughput studies. EXPERT OPINION: Multiple clinical and environmental risk factors have been identified. However, they have failed to provide practically effective prediction. Genetic and genomic risk factors identified from high-throughput studies have suffered a lack of reproducibility. The identification of genetic/genomic risk factors demands innovative statistical and bioinformatics tools. Although multiple analysis methods have been developed, there is still room for improvement. There is a critical need for well-designed, prospective, large-scale pangenomic studies.

Abstract
Dysregulation of apoptosis plays a crucial role in carcinogenesis. Thus, genetic alterations within caspase genes would be expected to provoke a deficient apoptotic signaling thereby facilitating the development of prostate cancer (PCa). In the present study we investigated whether three different polymorphisms in the caspase-5 and -3 genes are differentially expressed in PCa. In a hospital-based case control study in northern India, we genotyped 192 PCa patients and 225 unrelated healthy controls for caspase-5 (G>C) (T>C) and caspase-3 (G>A) polymorphisms using amplification refractory mutation system and polymerase chain restriction fragment length polymorphism methods. Data were statistically analyzed and variant genotype GG of caspase-3 demonstrated increased risk for PCa (odds ratio [OR]=2.72, p=0.005). Similarly variant allele carrier (AG+GG) (OR=1.53, p=0.034) and G allele (OR=1.54, p=0.005) were also statistically associated with PCa risk. High risk for PCa was also observed with respect to caspase-5 (CC) diplotypes (OR=21.67, p=0.012, Pc=0.048). We observed significantly enhanced risk for PCa due to interaction between caspase-3 and -5 gene polymorphisms. In association of genotypes with clinical characteristics, heterozygous TC genotype of caspase-5 (T>C) conferred risk with high Gleason grade tumor (OR=2.35, p=0.042). In case-only analysis, interaction of environmental risk factors and genotypes did not further modulate the risk for PCa. Our observations suggested positive association of caspase-3 and diplotype analysis of caspase-5 to be associated with PCa risk. Interaction of caspase-3 and -5 genotypes also modulated the PCa risk.

Abstract
Caspase-9 (CASP-9) is an initiator caspase protease for apoptosis, and plays an important role in the development and progression of lumbar disc disease (LDD). The expression and/or activity of CASP-9 are significantly enhanced in the degenerated disc. The polymorphism in the promoter region of CASP-9 enhances the transcriptional activity of this gene, thereby modulating the susceptibility to LDD. The current study investigated the relationship between the CASP-9 -1263A/G (rs4645978) and -712C/T (rs4645981) polymorphisms and discogenic low back pain (LBP). The CASP-9 -1263A/G and -712C/T genotypes in this study were defined by polymerase chain reaction in 154 patients with discogenic LBP and 216 controls that were frequency-matched by age, gender, and occupation. The results showed that the CASP-9 -1263 GG genotype, compared with the AA and AG genotypes [odds ratio (OR) = 1.997, 95% confidence interval (95% CI) = 1.216-3.279, p = 0.006] or the AA genotype (OR = 2.760, 95% CI = 1.464-5.203, p = 0.002), is associated with a significant increased risk of discogenic LBP, but the -712 TT or TT and CT genotypes do not contribute to discogenic LBP compared with the CC genotype (OR = 0.547, 95% CI = 0.200-1.494, p = 0.234 and OR = 0.669, 95% CI = 0.439-1.021, p = 0.062, respectively). These results indicated that the CASP-9 -1263A/G polymorphism is associated with a high risk of discogenic LBP.

Abstract
Despite decades of intensive research, NHL (non-Hodgkin lymphoma) still remains poorly understood and is largely incurable. Recent molecular studies suggest that genomic variants measured with SNPs (single nucleotide polymorphisms) in genes may have additional predictive power for NHL prognosis beyond clinical risk factors. We analyzed a genetic association study. The prognostic cohort consisted of 346 patients, among whom 138 had DLBCL (diffuse large B-cell lymphoma) and 101 had FL ( follicular lymphoma). For DLBCL, we analyzed 1229 SNPs which represented 122 KEGG pathways. For FL, we analyzed 1228 SNPs which represented 122 KEGG pathways. Unlike in existing studies, we targeted at identifying pathways with significant additional predictive power beyond clinical factors. In addition, we accounted for the joint effects of multiple SNPs within pathways, whereas some existing studies drew pathway-level conclusions based on separate analysis of individual SNPs. For DLBCL, we identified four pathways, which, combined with the clinical factors, had medians of the prediction logrank statistics as 2.535, 2.220, 2.094, 2.453, and 2.512, respectively. As a comparison, the clinical factors had a median of the prediction logrank statistics around 0.552. For FL, we identified two pathways, which, combined with the clinical factors, had medians of the prediction logrank statistics as 4.320 and 3.532, respectively. As a comparison, the clinical factors had a median of the prediction logrank statistics around 1.212. For NHL overall, we identified three pathways, which, combined with the clinical factors, had medians of the prediction logrank statistics as 5.722, 5.314, and 5.441, respective. As a comparison, the clinical factors had a median of the prediction logrank statistics around 4.411. The identified pathways have sound biological bases. In addition, they are different from those identified using existing approaches. They may provide further insights into the biological mechanisms underlying the prognosis of NHL.

Abstract
BACKGROUND The genes caspase-8 (CASP8) and caspase-10 (CASP10) functionally cooperate and play a key role in the initiation of apoptosis. Suppression of apoptosis is one of the major mechanisms underlying the origin and progression of cancer. Previous case-control studies have indicated that the polymorphisms CASP8 D302H and CASP10 V410I are associated with a reduced risk of breast cancer in the general population. METHODS To evaluate whether the CASP8 D302H (CASP10 V410I) polymorphisms modify breast or ovarian cancer risk in BRCA1 and BRCA2 mutation carriers, we analyzed 7,353 (7,227) subjects of white European origin provided by 19 (18) study groups that participate in the Consortium of Investigators of Modifiers of BRCA1/2 (CIMBA). A weighted cohort approach was used to estimate hazard ratios (HR) and 95% confidence intervals (95% CI). RESULTS The minor allele of CASP8 D302H was significantly associated with a reduced risk of breast cancer (per-allele HR, 0.85; 95% CI, 0.76-0.97; P(trend) = 0.011) and ovarian cancer (per-allele HR, 0.69; 95% CI, 0.53-0.89; P(trend) = 0.004) for BRCA1 but not for BRCA2 mutation carriers. The CASP10 V410I polymorphism was not associated with breast or ovarian cancer risk for BRCA1 or BRCA2 mutation carriers. CONCLUSIONS CASP8 D302H decreases breast and ovarian cancer risk for BRCA1 mutation carriers but not for BRCA2 mutation carriers. IMPACT The combined application of these and other recently identified genetic risk modifiers could in the future allow better individual risk calculation and could aid in the individualized counseling and decision making with respect to preventive options in BRCA1 mutation carriers.

Abstract
Several potentially functional polymorphisms of CASP8 encoding an apoptotic enzyme, caspase 8, have been implicated in cancer risk, but individually published studies showed inconclusive results. We performed a meta-analysis of 23 publications with a total of 55 174 cancer cases and 59 336 controls from 55 individual studies. We summarized the data on the associations between three studied CASP8 polymorphisms (G>C D302H, -652 6N del and Ex14-271A>T) and cancer risk and performed subgroup analysis by ethnicity, cancer type, study design and etiology. We found that D302H CC and CG variant genotypes were associated with significantly reduced overall risk of cancers using conservative random genetic models [homozygote comparison: odds ratios (OR) = 0.79; 95% confidence interval (CI): 0.69-0.92; dominant comparison: OR = 0.93, 95% CI: 0.89-0.98; recessive comparison: OR = 0.81, 95% CI: 0.71-0.93). In further stratified analyses, the reduced cancer risk remained for subgroups of Caucasians, breast or estrogen-related cancers, and hospital- or population-based studies, except for an elevated risk for brain tumors. Similarly, the -652 6N del polymorphism was also associated with significantly reduced overall risk of cancers (homozygote comparison: OR = 0.84, 95% CI: 0.75-0.94; dominant comparison: OR = 0.88, 95% CI: 0.81-0.96; recessive comparison: OR = 0.90, 95% CI: 0.82-0.99) and all subgroups analyzed. However, the Ex14-271A>T polymorphism did not appear to have an effect on cancer risk. These results suggest that CASP8 D302H and -652 6N del polymorphisms are potential biomarkers for cancer risk.

Abstract
Caspase 8 (CASP8) is an apoptosis-related cysteine peptidase involved in the death receptor pathway and likely in the mitochondrial pathway. A CASP8 promoter region six-nucleotide deletion/insertion (-652 6N ins/del) variant and a coding region D302H polymorphism are reportedly important in cancer development, but no reported study has assessed the associations of these genetic variations with risk of head and neck cancer. In a hospital-based study of non-Hispanic whites, we genotyped CASP8 -652 6N del and 302H variants in 1,023 patients with squamous cell carcinoma of the head and neck (SCCHN) and 1,052 cancer-free controls. Crude and adjusted odds ratios (OR) and 95% confidence intervals (CI) were estimated using unconditional logistic regression models. The CASP8 -652 6N del variant genotypes or haplotypes were inversely associated with SCCHN risk (adjusted OR, 0.70; 95% CI, 0.57-0.85 for the ins/del + del/del genotypes compared with the ins/ins genotype; adjusted OR, 0.73; 95% CI, 0.55-0.97 for the del-D haplotype compared with the ins-D haplotype). Furthermore, the number of the CASP8 -652 6N del (but not 302H) variant allele tended to correlate with increased levels of camptothecin-induced p53-mediated apoptosis in T lymphocytes from 170 cancer-free controls. We concluded that the CASP8 -652 6N del variant allele may contribute to the risk of developing SCCHN in non-Hispanic white populations. Further validation by population-based case-control studies and rigorous mechanistic studies is warranted.

Abstract
MOTIVATION Although NHL (non-Hodgkin's lymphoma) is the fifth leading cause of cancer incidence and mortality in the USA, it remains poorly understood and is largely incurable. Biomedical studies have shown that genomic variations, measured with SNPs (single nucleotide polymorphisms) in genes, may have independent predictive power for disease-free survival in NHL patients beyond clinical measurements. RESULTS We apply the CTGDR (clustering threshold gradient directed regularization) method to genetic association studies using SNPs, analyze data from an association study of NHL and identify prognosis signatures to diffuse large B cell lymphoma (DLBCL) and follicular lymphoma (FL), the two most common subtypes of NHL. With the CTGDR method, we are able to account for the joint effects of multiple genes/SNPs, whereas most existing studies are single-marker based. In addition, we are able to account for the 'gene and SNP-within-gene' hierarchical structure and identify not only predictive genes but also predictive SNPs within identified genes. In contrast, existing studies are limited to either gene or SNP identification, but not both. We propose using resampling methods to evaluate the predictive power and reproducibility of identified genes and SNPs. Simulation study and data analysis suggest satisfactory performance of the CTGDR method.

Abstract
Caspases play a critical role in regulation of apoptosis, cell differentiation, inflammation, and innate immunity, and several are mutated or have altered expression in non-Hodgkin lymphoma (NHL). To study the impact of genetic variation in caspases on NHL risk, we analyzed tag single nucleotide polymorphisms (SNPs) in 12 caspase and related genes in 3 population-based case-control studies (1946 cases and 1808 controls). Gene-based analysis, adjusting for the number of tagSNPs genotyped in each gene, showed significant associations for CASP8, CASP9, and CASP1. SNP-based analysis showed that CASP8 rs6736233 (odds ratio (OR) (CG) = 1.21; OR(CC) = 2.13; P trend = .011); CASP9 rs4661636 (OR(CT) = 0.89; OR(TT) = 0.77; P trend = .011); and CASP1 rs1785882 (OR(AT) = 1.12; OR(AA) = 1.30; P trend = .0054) were significantly associated with NHL risk and consistent across studies. It is noteworthy that genetic variants in CASP8 were associated with risk of all major NHL subtypes. Our findings suggest that genetic variation in caspases may play an important role in lymphomagenesis.

Abstract
Genetic polymorphism in DNA repair genes may influence individual variation in DNA repair capacity, which may be associated with cancer risks. This hospital-based case-control study examined whether polymorphism in the DNA repair gene x-ray repair cross-complementing groups 1 (XRCC1 Arg194Trp [C-->T], Arg280His [G-->A], and Arg399Gln [G-->A]) played a role in susceptibility to non-Hodgkin's lymphoma (NHL) in the Chinese population. We genotyped these polymorphisms for 221 histopathologically confirmed NHL cases and 254 age- and sex-matched healthy control cases in China. No studied polymorphism alone was shown to be related to the risk of NHL or each histologic subtype of NHL. When stratified by smoking status, however, the XRCC1Arg399Gln variant genotypes (homozygotes and heterozygotes) were associated with a 3.0-fold risk of follicular lymphoma among heavy smokers (95% confidence interval: 1.16-7.82; P = 0.02). Further large-scale studies would confirm this association and clarify marginally significant trends in XRCC1 polymorphism combinations for an increased risk for NHL.

Abstract
Caspase-3, caspase-7, and caspase-8 are important caspases in the apoptosis pathway and play an important role in the development and progression of cancer. We examined the association between genetic variants in the caspase-3, caspase-7, and caspase-8 genes and risk for endometrial cancer among Chinese women. Genotypes for 1,028 women with endometrial cancer and 1,003 healthy controls were determined with the Affymetrix MegAllele Targeted Genotyping System and Molecular Inversion Probe method. Of 35 selected single-nucleotide polymorphisms, four in the caspase-7 gene were in high linkage disequilibrium (rs11593766, rs3124740, rs11196445, and rs11196418) and associated with the risk for endometrial cancer. The AA genotype of rs11196418 [odds ratio, 0.36; 95% confidence interval (95% CI), 0.14-0.94] and the G allele of rs11593766 were associated with reduced risk (odds ratio of 0.75 and 95% CI of 0.59-0.96 for carriers of one G allele; odds ratio of 0.70 and 95% CI of 0.24-2.03 for carriers of two G alleles). The AA genotype of rs11196445 (odds ratio, 1.74; 95% CI, 0.99-3.05), the CC genotype of rs3124740 (odds ratio, 1.36; 95% CI, 1.06-1.75), and the GG genotype of rs10787498 in the caspase-7 gene (odds ratio, 1.90; 95% CI, 1.16-3.11) were associated with increased risk compared with homozygotes of the major alleles. The gene-disease association seemed to be more pronounced among premenopausal women, although tests for multiplicative interaction between genes and menopausal status failed to reach statistical significance. The GG genotype of rs2705901 in the caspase-3 gene was significantly associated with increased cancer risk compared with the CC genotype (odds ratio, 2.25; 95% CI, 1.03-4.95). No association was observed between polymorphisms of the caspase-8 gene and risk for endometrial cancer. These findings suggest that genetic variants in caspase-3 and caspase-7 may play a role in endometrial cancer susceptibility.

Abstract
Genetic variation may be an important risk factor for multiple myeloma. A hallmark of tumor formation and growth is cell cycle dysregulation and apoptosis avoidance. We previously reported the association of genetic variation in caspase genes, the apoptotic-regulating family, and multiple myeloma risk. To further examine if genetic variation in key cell cycle and apoptosis genes alters multiple myeloma risk, we genotyped 276 tag SNPs in 27 gene regions in a population-based case-control study of non-Hispanic Caucasian women (108 cases; 482 controls) in Connecticut. Logistic regression assessed the effect of each SNP on multiple myeloma risk and the minP test assessed the association at the gene region level. Three gene regions were significantly associated with risk of multiple myeloma (BAX minP=0.018, CASP9 minP=0.025, and RIPK1 minP=0.037). Further explorations identified the most significant variant of BAX, RIPK1, and CASP9 to be rs1042265, rs9391981, and rs751643, respectively. The A variant at rs1042265 (OR(GA+AA)=0.40, 95% CI=0.21-0.78) and the C variant at rs9391981 (OR(GC+CC)=0.32, 95% CI=0.12-0.81) were associated with a decreased risk of multiple myeloma. The G variant at rs7516435 was associated with an increased risk of multiple myeloma (OR(AG)=1.48, 95% CI=0.94-2.32; OR(GG)=2.59, 95% CI=1.30-5.15; p(trend)=0.005). Haplotype analyses supported the SNP findings. These findings suggest that genetic variation in cell cycle and apoptosis genes may play a key role in multiple myeloma and warrant further investigation through replication studies.

Abstract
PURPOSE Caspase-3 plays a central role in executing cell apoptosis and thus in carcinogenesis, but little is known about the role of CASP3 variants in susceptibility to SCCHN. EXPERIMENTAL DESIGN Genotype and haplotypes of the first intron (rs4647601:G>T and rs4647602:C>A) and 5'-untranslated region (UTR; rs4647603:G>A) of CASP3 (NT_022792.17) were determined for 930 SCCHN patients and 993 cancer-free controls in a U.S. non-Hispanic white population. Odds ratio (OR) and 95% confidence interval (95% CI) were calculated in multivariate logistic regression analysis. RESULTS We found that the CASP3 rs4647601:TT variant genotype was associated with an increased risk of SCCHN (adjusted OR, 1.32; 95% CI, 1.00-1.73) compared with the GG genotype. This risk was more evident in the subgroups of younger (< or =56 years) subjects, males, and never smokers with a significant trend for increased risk with increased number of variant T allele (P < 0.05 for all). However, these risks were not found for other two SNPs. Furthermore, individuals with two copies of haplotypes TCG or GCA were found to have a significant increased risk of SCCHN (OR, 1.31; 95% CI, 1.07-1.61) compared with the other haplotypes, and this risk was more evident in less advanced diseases (OR, 1.45; 95% CI, 1.11-1.89) than in the advanced diseases (OR, 1.22; 95% CI, 0.96-1.54). CONCLUSIONS These results suggested that genetic variation in CASP3 may contribute to SCCHN risk. Larger studies are needed to confirm our findings.

Abstract
Multiple myeloma is a haematological malignency, characterized by clonal expansion of plasma cells. However, little is known about the cause of multiple myeloma. Cancer cells must avoid apoptosis to ensure unregulated tumour formation and growth. The highly conserved caspase cascade is essential to the regulation of the apoptotic pathway. To examine if five single nucleotide polymorphisms (SNPs) in four caspase genes [CASP3 Ex8-280 C > A (rs6948), CASP3 Ex8 + 567 T > C (rs1049216), CASP8 Ex14-271 A > T (rs13113), CASP9 Ex5 + 32 G > A (rs1052576), CASP10 Ex3-171 A > G (rs39001150)] alter multiple myeloma risk, we conducted a population-based case-control study of women (128 cases; 516 controls) in Connecticut. Compared to individuals with the TT genotype of CASP3 Ex8 + 567 T > C, subjects with the CC genotype had a five-fold decreased risk of multiple myeloma (odds ratio (OR)(CC) = 0.2, 95% confidence interval (CI) = 0.0-1.0). Further, individuals with the AG and AA genotypes of CASP9 Ex5 + 32 G > A also experienced a decreased risk of multiple myeloma (OR(AG) = 0.8, 95% CI = 0.5-1.3; OR(AA) = 0.5, 95% CI = 0.3-0.9; p-trend = 0.02). While no previous study has evaluated the association between caspase genes and multiple myeloma, studies have found associations with lung, breast, esophageal, gastric, colorectal and cervical cancers. Our parallel study of non-Hodgkin lymphoma, which utilized the same controls, found strong evidence that caspase genes play a key role in lymphogenesis. The protective associations observed in two key caspase genes suggest that genetic variation in CASP genes may play an important role in the aetiology of multiple myeloma.

Abstract
Common genetic variants are thought to increase the risk of chronic lymphocytic leukaemia (CLL), and case-control studies provide an approach to detect these variants. There have been multiple candidate gene studies published to date, but relatively few disease pathway studies or large genomic association studies. We summarize the results of these previous studies, as well as present results from our recent large pathway study of 9412 single nucleotide polymorphisms from 1253 immunity and inflammation genes in a study of 126 CLL cases and 484 frequency-matched controls. Several promising genes have been identified as susceptibility genes for risk of CLL across all of these association studies. However, a number of candidate gene studies have not been replicated in follow-up studies, whereas the results from disease pathway and large genomic studies have yet to be replicated in an independent sample. The challenge of future studies of this type will be overcoming study design issues, including definition of CLL, sample size limitations and multiple testing issues.
