Abstract
BACKGROUND several studies have been performed to investigate the association of TNF-α-308G>ASNP and CLL susceptibility However, the results are inconsistent. This study aimed to investigate the association between TNF-α-308G>ASNP of the TNF-α gene and CLL risk in the Sudanese population and correlated genotypes with clinicopathological features. METHODS A case-control study was conducted in Khartoum state, during the period from April 2017 to April 2018, involved 110 CLL patients and 50 healthy volunteers. Physical examination, Complete Blood Count, and immunophenotype were performed in all patients to confirm the diagnosis. Clinical staging such as Rai and Binet were studied. CD38 and ZAP70 were performed by Flow Cytometry. Blood samples were collected from all participants; DNA was extracted by using ANALYTIKJENA Blood DNA Extraction Kit and analyzed TNF-α-308G>ASNP by using AS-PCR. The statistical analysis was performed using SPSS. RESULTS TNF-α-308G>A genotype frequencies were GG (10.0%), GA (87.3%), and AA (2.7%) among the CLL patients, and GG (14.0%), GA (80.0%), and AA (6.0%) in the control group. The comparison of CLL patients with the control group did not show any statistically significant relationship for the genotypic and allelic frequencies. Furthermore, no association was observed between the TNF-α-308G>ASNP and gender, hematological parameters, clinical stages systems, CD38 expression, and ZAP-70 expression. The presence of theTNF-α-308Aallele was associated with a lower mean age. CONCLUSIONS These results indicate that TNF-α-308G>A genotypes are not involved in the predisposition to the development of CLL. TNF-α-308A allele carrier induced to development of CLL at an earlier age.

Interleukin-10-1082A>G (rs1800896) Single Nucleotide Polymorphism is Not a Risk Factor of Chronic Lymphocytic Leukemia in Sudanese Population. Asian Pac J Cancer Prev 2022; 23:3229-3235.

Abstract
OBJECTIVE The present study was conducted to examine the association between the IL-10-1082A>G (rs 1800896) polymorphism and risk of Chronic Lymphocytic Leukemia and to assess the correlation between this polymorphism and clinicopathological characters. METHODS A case-control study was conducted in Khartoum state, Sudan, during the period from April 2017 to April 2018, involved 110 CLL patients and 80 healthy volunteers as a control group. Physical examination, complete blood count, and immunophenotype were performed in all patients to confirm the diagnosis. Clinical staging such as Rai and Binet were studied. CD38 and ZAP70 were performed by flow cytometry. Blood samples were collected from all participants; DNA was extracted by using ANALYTIKJENA Blood DNA Extraction Kit and analyzed IL-10-1082A>G polymorphism by using Allele Specific-Polymerase Chain Reaction. The statistical analysis was performed using statistical package for social sciences version 23.0 software. RESULTS Frequency of AA, AG, and GG genotypes was 32.7%, 55.5%, and 11.8% for the patient group and 31.25%, 51.25%, and 17.5% in the control group, respectively. The genotype of IL-10 (-1082A>G) did not associate with susceptibility of CLL in our population. The study showed that the G allele of the IL-10 gene (-1082A>G) is associated with the male sex. However, no significant association was found between -1082A>G genotype and clinicopathological characters. CONCLUSION Our results do not support the involvement of the IL-10 -1082A>G promoter gene polymorphism in the increased CLL susceptibility. IL-10-1082G allele (IL-10-1082AG or IL-10-1082GG) was found more frequently in males. Furthermore, no association was observed between the IL-10-1082A>G polymorphism and clinical stages systems as well as established poor prognostic markers. Finally, within the group of patients with CLL, there was no difference in the age at diagnosis and hematological parameters according to genotype distributions.

Predominant VH1-69 IgBCR Clones Show Higher Expression of CD5 in Heterogeneous Chronic Lymphocytic Leukemia Populations. Front Oncol 2021; 11:703254.

Abstract
The immunoglobulin B cell receptor (IgBCR) expressed by chronic lymphocytic leukemia (CLL) B cells plays a pivotal role in tumorigenesis, supporting neoplastic transformation, survival, and expansion of tumor clones. We demonstrated that in the same patient, two or more CLL clones could coexist, recognized by the expression of different variable regions of the heavy chain of IgBCR, composing the antigen-binding site. In this regard, phage display screening could be considered the easier and most advantageous methodology for the identification of small peptide molecules able to mimic the natural antigen of the tumor IgBCRs. These molecules, properly functionalized, could be used as a probe to specifically identify and isolate single CLL subpopulations, for a deeper analysis in terms of drug resistance, phenotype, and gene expression. Furthermore, CLL cells express another surface membrane receptor, the CD5, which is commonly expressed by normal T cells. Piece of evidence supports a possible contribution of CD5 to the selection and maintenance of autoreactivity in B cells and the constitutive expression of CD5 on CLL cells could induce pro-survival stimuli. In this brief research report, we describe a peptide-based single-cell sorting using as bait the IgBCR of tumor cells; in the next step, we performed a quantitative analysis of CD5 expression by qRT-PCR related to the expressed IgBCR. Our approach could open a new perspective for the identification, isolation, and investigation of all subsets of IgBCR-related CLL clones, with particular attention to the more aggressive clones.
