Introduction: Zamzam water is blessed water originated from Mecca and is believed by Muslims to have the ability to cure illness. This ability to cure illness is due to the fact that zamzam water has higher concentration of minerals especially sodium, calcium and magnesium which play a vital role. Sodium is reported to be involved in the regulation of the Mu-Opioid Receptor, which indirectly leads to the production of cAMP. Hence, this current study was carried out to investigate the synergistic effects of zamzam water and methadone combination on cAMP levels in human primary glioblastoma cell line (U-87 MG) after chronic morphine administration. Materials and Methods: The time course and concentration of morphine on U-87 MG cell line was determined. The U-87 MG cell line was incubated with morphine (25 µL/mL) for 24h, to make the cell dependent on morphine and later treated with different combinations of 3.2 mL of zamzam water and methadone (5, 10, 25 µL/mL). The levels of cAMP was determined using the enzyme-linked immunosorbent assay kit. Results: The result revealed that 3.2 mL of zamzam water incubated with 10 µl/ mL of methadone significantly prevented the overshoot production of cAMP level (p<0.05) in U-87 MG cell line after 48h incubation when compared to the untreated samples. Conclusion: These finding suggest that co-treatment with zamzam water and methadone could possibly avoid tolerance and dependence on chronic morphine treatment by preventing the up-regulation of cAMP level.><0.05 in U-87 MG cell line after 48h incubation when compared to the untreated samples.

BACKGROUND: Gliomas are the most common primary brain tumors, representing 50–60% of malignant primary brain tumors. Gliomas are highly heterogeneous with marked inter- and intratumoral diversity. Gliomas heterogeneity is a challenging issue in the development of personalized treatment. The simplest method for studying heterogeneity is using ex vivo cell cultures; in our case, the cell lines were isolated from patient with glioblastomas. AIM: Here, we reported distinct cell subpopulations heterogeneity in glioblastoma cells. METHODS: Human glioblastoma cells isolation is conducted by enzymatic method with combination of collagenase I, hyaluronidase, and trypsin enzyme in proportional amount from patient. Immunostaining was performed to assess glial fibrillary acidic protein (GFAP), Ki-67, isocitrate dehydrogenase-1 (IDH-1) status, and program death ligand-1 (PD-L1) expression. Primary glioblastoma cell line was characterized by flow cytometry (fluorescence-activated cell sorting) analysis based on cluster of differentiation (CD) 133 and CD15 marker expression. U87MG and CGNH-89 cell lines were used as control. Distinct subpopulation analysis was performed by double staining of CD133 and CD15 in isolated primary glioblastoma cell line and its comparative control cells. RESULTS: Our isolated glioblastoma cells morphology was adherent cells which were able to form spheres depending on environment. Immunostaining confirmed GFAP, Ki-67, IDH-1 mutants, and PD-L1 expression. Our isolated glioblastoma cells expressed CD133 and CD15, coexpressed CD133/CD15 in different patterns. The highest subpopulation in primary glioblastoma was CD133+/CD15+. CONCLUSION: Glioblastoma cells can be isolated using enzymatic methods. Isolated glioblastoma cells consist of four different subpopulations distinguished by CD133/CD15 double staining. Intratumoral heterogeneity exists and directly or indirectly depends on their microenvironment.

Glioblastoma multiforme (GBM) has remained one of the most lethal and challenging cancers to treat. Previous studies have shown encouraging results when irinotecan was used in combination with temozolomide (TMZ) for treating GBM. However, irinotecan has a narrow therapeutic index: a slight dose increase in irinotecan can induce toxicities that outweigh its therapeutic benefits. SN-38 is the active metabolite of irinotecan that accounts for both its anti-tumor efficacy and toxicity. In our previous paper, we showed that SN-38 embedded into 50:50 biodegradable poly[(d,l)-lactide-co-glycolide] (PLGA) microparticles (SMPs) provides an efficient delivery and sustained release of SN-38 from SMPs in the brain tissues of rats. These properties of SMPs give them potential for therapeutic application due to their high efficacy and low toxicity. In this study, we tested the anti-tumor activity of SMP-based interstitial chemotherapy combined with TMZ using TMZ-resistant human glioblastoma cell line-derived xenograft models. Our data suggest that treatment in which SMPs are combined with TMZ reduces tumor growth and extends survival in mice bearing xenograft tumors derived from both TMZ-resistant and TMZ-sensitive human glioblastoma cell lines. Our findings demonstrate that combining SMPs with TMZ may have potential as a promising strategy for the treatment of GBM.
