Genetic studies on the KL gene have revealed that DNA hypermethylation is one of the major risk factors for aging, diseases, and cancer. Besides, KL exerts anti-inflammatory and anti-tumor effects by regulating signaling pathways and the expression of target genes. KL participates in modulation of the insulin/insulin-like growth factor-1 (IGF-1) signaling, which induces the growth hormone (GH) secretion. Accordingly, KL mutant mice display multiple aging-like phenotypes, which are ameliorated by overexpression of KL. Therefore, KL is an important contributor to lifespan. KL is further identified as a regulator of calcium (Ca2+) channel-dependent cell physiological processes. KL has been also shown to induce cancer cell apoptosis, thus, it is considered as a potential tumor suppressor. Our recent studies have indicated that KL modulates an influx of Ca2+ from the extracellular space, leading to a change in CCL21-dependent migration in dendritic cells (DCs). Interestingly, the regulation of the expression of KL was mediated through a phosphoinositide 3-kinase (PI3K) pathway in DCs. Moreover, downregulating of KL expression by using siRNA knockdown technique, we observed that the expression of Ca2+ channels including Orai3, but not Orai1, Orai2, TRPV5 and TRPV6 was significantly reduced in KL-silenced as compared to control BMDCs. Clearly, additional research is required to define the role of KL in the regulation of organismic and cellular functions through the PI3K signaling and the expression of the Ca2+ channels.}, keywords = {Aging,Ca2+ channel,Cancer,Dendritic cells,Klotho}, url = {https://ijbms.mums.ac.ir/article_9892.html}, eprint = {https://ijbms.mums.ac.ir/article_9892_28125904f08cd9146deb296fba32759e.pdf} } @article { author = {Abutorabzadeh, Sayyed Mohammad and Mosafa, Fatemeh and Hadizadeh, Farzin and Ghodsi, Razieh}, title = {Design, synthesis, and biological evaluation of 6-methoxy-2-arylquinolines as potential P-glycoprotein inhibitors}, journal = {Iranian Journal of Basic Medical Sciences}, volume = {21}, number = {1}, pages = {9-18}, year = {2018}, publisher = {Mashhad University of Medical Sciences}, issn = {2008-3866}, eissn = {2008-3874}, doi = {10.22038/ijbms.2017.24476.6092}, abstract = {Objective(s): In the present study,a new series of 6-methoxy-2-arylquinoline analogues was designed and synthesized as P-glycoprotein (P-gp) inhibitors using quinine and flavones as the lead compounds.

Compounds showing low to moderate toxicity in the MTT test were selected to investigate their P-gp inhibition activity.

Materials and Methods: Isolation and confirmation of hWJ-MSCs from human umbilical cord was performed. Eight rabbits at gestational day 14 were anesthetized. All rabbits carried pregnancies to term yielding 40 rabbit fetuses. Intrauterine injection of hWJ-MSCs was performed in 24 fetuses. Twenty-seven fetuses were born alive. Ten liver samples from injected fetuses were sampled, eight rabbits 3 days after birth and two rabbits 21 days after birth. The non-injected fetuses served as positive control. Fetuses of non-injected rabbits were negative controls. Using real-time polymerase chain reaction (RT-PCR), mRNA expression of albumin (ALB), α-fetoprotein (AFP), hepatic nuclear factor 4 (HNF4), and CYP2B6 (CYP) were detected in liver samples. Results: The human ALB, AFP, HNF4, and CYP mRNAs were expressed in the injected sampled fetuses by hWJ-MSCs into fetuses of rabbits in utero. Conclusion: Developing xenotransplantation of hWJ-MSCs into rabbit uterus can introduce an applied approach for producing human liver tissue in rabbits.}, keywords = {Human,Liver,Mesenchymal stem cells,Rabbit,Wharton jelly,Xenotransplantation}, url = {https://ijbms.mums.ac.ir/article_9926.html}, eprint = {https://ijbms.mums.ac.ir/article_9926_0d97b957deb40fba1120f9a5bf380ceb.pdf} } @article { author = {Mohamed Abd-Allah, Amany Ahmed and Mohamed Nasr El-Deen, Nasr Abdelwahab and mohamed, wafaa and Mohamed Naguib, Fatma}, title = {Mast cells and pro-inflammatory cytokines roles in assessment of grape seeds extract anti-inflammatory activity in rat model of carrageenan-induced paw edema}, journal = {Iranian Journal of Basic Medical Sciences}, volume = {21}, number = {1}, pages = {97-107}, year = {2018}, publisher = {Mashhad University of Medical Sciences}, issn = {2008-3866}, eissn = {2008-3874}, doi = {10.22038/ijbms.2017.25067.6219}, abstract = {Objective(s): Reactive oxygen species (ROS)-produced oxidative disorders were involved at the pathophysiology of many inflammatory processes via the generation of pro-inflammatory cytokines and antioxidant defense system suppression. Although herbal antioxidants as mono-therapy relief many inflammatory diseases including, autoimmunity rheumatoid arthritis, but as combination therapy with other proven anti-inflammatory drugs in order to decreasing their toxic impacts has not yet been studied clearly, especially against chemical substances that’s induced local inflammation with characteristic edema. Materials and Methods: Grape seeds extract (GSE) at a concentration of 40 mg/kg B. wt alone or in combination with indomethacin (Indo.) at a dose of 5 mg/Kg B. wt orally given for 10 days prior (gps VI, VII, VIII) or as a single dose after edema induction (gps IX, X, XI) in rat's left hind paw by sub-planter single injection of 0.1 carrageenan: saline solution (1%) (gp. V) to assess the prophylactic and therapeutic anti-inflammatory activities of both through  the estimation of selective inflammatory mediators and oxidative damage-related biomarkers as well as tissue mast cell scoring. Furthermore, both substances were given alone (gps II, III, IV) for their  blood, liver and kidney safety evaluation comparing with negative control rats (gp. I) which kept without medication. Results: A marked reduction on the inflammatory mediators, edema volume and oxidative byproducts in edema bearing rats' prophylactic and treated with grape seeds extract and indomethacin was observed. Indomethacin found to induce some toxicological impacts which minimized when administered together with GSE.

The disease is characterized by sensorineural hearing loss and long QT syndrome. Methods: Here we present a 3.5-year-old female patient, an offspring of consanguineous marriage, who had a history of recurrent syncope and congenital sensorineural deafness. The patient and the family members were screened for mutations in KCNQ1 gene by linkage analysis and DNA sequencing. Results: DNA sequencing showed a c.1532_1534delG (p. A512Pfs*81) mutation in the KCNQ1 gene in homozygous form. The results of short tandem repeat (STR) markers showed that the disease in the family is linked to the KCNQ1 gene. The mutation was confirmed in the parents in heterozygous form. Conclusion: This is the first report of this variant in KCNQ1 gene in an Iranian family.
