Plasma Jet Prepared Gold and Silver Nanoparticles to Induce CaspaseIndependent Apoptosis in Digestive System Cancers Mohammed Subhi Mohammed, Ban H. Adil, A.S. Obaid, Ahmed Majeed Al-Shammari Materials Science Forum, 2022 Alot of medical and industrial applications used the metal nanoparticles (NPs) with increase interest to be used as cancer therapy. The current work aimed to prepare AuNPs and AgNPs through the use of plasma jet and test their antitumor mechanism of apoptosis induction. The results indicating the face-centered cubic structures and crystalline nature of AuNPs and AgNPs. Also, the image of FESEM showed that the well dispersions regarding AuNPs and AgNPs, while the NP’s spherical shape with the particle size distributions which are considered to be close that estimated from the XRD. cytotoxicity have been assessed against the Normal embryonic cell line REF and the digestive system (HC , SK-GT-4) cell lines under a variety of the series dilute of the Ag and Au NPs (6.25, 12.5, 25, 50 and 100%), have been determined through a microtetrazolium (MTT) assay. The capacity of Ag and Au NPs to induce apoptosis to an infected cell has been studied by crystal violet stain to measure the percentage of induction of apoptosis. In cases where 100 μg\\ml Au NP concentrations are 69.60 percent, the maximum cytotoxicity of the HC cell line was reported, while 100 μg\\ml Au NP was 69.20% for the SKg cell line exposure. qRT-PCR in AuNPs and AgNPs treated of (HC and SKG) cell lines revealed a remarkable in the expression of BAX, BCL2 and AIF, Endo G (independent pathway).
Effect of the Concentration Levels of Growth Hormone and Insulin-like Growth Factor i on the Polymorphisms of the Il12p40 Gene in Lung Cancer Patients Ameer Ali Imarah, M Subhi Mohammed, Rana Ahmed Najm, Mohammad Al Zeyadi, Sinan Qayes Khayoon, et al. Archives of Razi Institute, 2022 The prevalence of lung cancer as one of the most common cancers with the highest mortality rate is one of the most important health problems in humans across the world. Molecular research can provide valuable information about genetic changes associated with the pathogenesis of the disease that may be used to improve prognosis and treatment. The current study aimed to examine the genotyping utility of the Il12p40 (IL-12B) gene (rs3212227, A>C) polymorphisms and detect its relationship with the concentration levels of HGH and IGF-1 for the non-small cell lung carcinoma (NSCLC). This study investigated 67 cases with NSCLC (60 males and 7 females) and 28 healthy individuals as controls. The serum level of HGH and IGF-1 was determined using an enzyme-linked immunosorbent assay. Genotyping of the IL-12B gene polymorphisms (rs3212227, A>C) was carried out by polymerase chain reaction-restriction fragment length polymorphism. The serum levels of the HGH and IGF-1 were estimated, and the results of the IL-12B genotyping showed an increased risk of NSCLC. The homozygous wild (AA) genotype of the IL-12 gene showed that the risk of NSCLC was higher than that of the heterozygous (AC) and homozygous genotypes (CC). Moreover, a significant elevation was found in the serum levels of the HGH in the NSCLC patients, compared to the control group. The result showed that the IL-12 gene polymorphism was implicated in the pathogenesis of the NSCLC and directed several metabolic changes.
Retinoic acid treatment of human hematological malignancies induces caspase dependent and independent apoptotic cell death Mohammed S. Mohammed1 , Maha Fakhry Altaee2 , Ahmed Majeed Al-Shammari3 Indian Journal of Forensic Medicine and Toxicology, 2021 The unprejudiced of this education is to gauge the ability of the retinoic acid to induce apoptotic cell deathin hematological tumors through caspase dependent or independent apoptotic pathway, The cytotoxicityeffects of retinoic acid of different concentrations (400,350,300,250,200,150,100,50,25,12.5 µg\ml) andexposure for all hematological malignancy cell lines (Human non-Hodgkin lymphoma SR and humanmultiple myeloma (COLO 677) and Human Monocytic Leukemia THP1 and Acute promyelocytic leukemiaNB4) have been determined using a microtetrazolium (MTT) assay. Propodeum iodide and alcidine orange(AO/PI) paired discoloration was used to study the ability of retinoic acid to induce apoptosis in the infectedcells and examined under fluorescence microscope and quantified for the percentage of apoptosis induction.Quantitative immunocytochemistry assay was used to study the caspase dependent and independentproteins expression in infected and control cells. Cells treated with Retinoic Acid showed increased celldeath percentage compared to the untreated cells as quantified by MTT assay. AO/PI results revealed thatRetinoic Acid had powerful effect on inducing apoptosis significantly (p<0.001) in human cancer cell linestested, compared to control cell. Immunocytochemistry in Retinoic Acid infected human hematological celllines revealed remarkable increase in expression of caspase 8,9 (dependent pathway) and AIF, ENDOG(independent pathway) induces a significant (p<0.002) as compared untreated cell.This study, which shows the role of the Retinoic Acid in inducing apoptosis through a dependent andindependent pathway in cancer cells, we anticipation these annotations will shanty light on the impendingexploration of retinoic acid in cancer hindrance and rehabilitation

Caspase dependent and independent anti-hematological malignancy activity of AMHA1 attenuated newcastle disease virus M. S. Mohammed, Maha F. Al-Taee, Ahmed Majeed Al-Shammari International Journal of Molecular and Cellular Medicine, 2019 Hematological malignancies remain one of the leading causes of death worldwide despite advances in cancer therapeutics. Newcastle disease virus (NDV) is a member of Paramyxoviridae that elicits considerable interest as an anticancer agent because it can replicate up to 10 000 times faster in human cancer cells than in most normal cancer cells. Several NDV strains reportedly induce the cytolysis of cancerous cell lines. The attenuated Iraqi strain (AMHA1) of NDV is a novel oncolytic agent with promising antitumor characteristics, including apoptosis induction. This study aimed to evaluate the ability of the AMHA1 NDV strain to induce apoptotic cell death in hematological tumors through caspase-dependent or independent apoptotic pathways. The cytolytic effects of AMHA1 NDV strains of different multiplicity of infection (MOIs) (20, 15,10, 5, 3, 1, 0.5, and 0.1 )and exposure for all hematological malignancy cell lines (human non-Hodgkin lymphoma SR and human multiple myeloma (COLO 677) and human monocytic leukemia THP1) have been determined through a microtetrazolium (MTT) assay. Propidium iodide and acridine orange (AO/PI) double staining were used to examine the ability of attenuated NDV strain to induce apoptosis in infected cells under a fluorescence microscope and to quantify the percentage of apoptosis induction. Quantitative immunocytochemistry assay was further used to study the caspase-dependent and independent protein expression levels in infected and control cells. Cells treated with NDV strains showed a higher cell-death percentage than untreated cells as quantified by the MTT assay. AO/PI results revealed that NDV exerted a powerful and significant effect on apoptosis induction (P<0.0001) in the human cancer cell lines tested in comparison with control cells. Immunocytochemistry in AMHA1 NDV- infected human hematological cell lines revealed a remarkable increase in the expression of caspase 8, 9 (dependent pathway), apoptosis-inducing factor, and endonuclease G (independent pathway) in comparison with untreated cells. This study demonstrated the role of the Iraqi NDV strain in inducing apoptosis through dependent and independent pathways in cancer cells and thus its high potential as an antitumor agent.
