Abstract
BACKGROUND Colorectal cancer (CRC) remains a significant contributor to mortality, often exacerbated by metastasis and chemoresistance. Novel therapeutic strategies are imperative to enhance current treatments. The dysregulation of the PI3K/Akt signaling pathway is implicated in CRC progression. This study investigates the therapeutic potential of Wortmannin, combined with 5-fluorouracil (5-FU), to target the PI3K/Akt pathway in CRC. METHODS Anti-migratory and antiproliferative effects were assessed through wound healing and MTT assays. Apoptosis and cell cycle alterations were evaluated using Annexin V/Propidium Iodide Apoptosis Assay. Wortmannin's impact on the oxidant/antioxidant equilibrium was examined via ROS, SOD, CAT, MDA, and T-SH levels. Downstream target genes of the PI3K/AKT pathway were analyzed at mRNA and protein levels using RTPCR and western blot, respectively. RESULTS Wortmannin demonstrated a significant inhibitory effect on cell proliferation, modulating survivin, cyclinD1, PI3K, and p-Akt. The PI3K inhibitor attenuated migratory activity, inducing E-cadherin expression. Combined Wortmannin with 5-FU induced apoptosis, increasing cells in sub-G1 via elevated ROS levels. CONCLUSION This study underscores Wortmannin's potential in inhibiting CRC cell growth and migration through PI3K/Akt pathway modulation. It also highlights its candidacy for further investigation as a promising therapeutic option in colorectal cancer treatment.

Abstract
Objective(s): Dental pulp stem cells (DPSCs) can differentiate into functional neurons and have the potential for cell therapy in neurological diseases. Granulocyte colony-stimulating factor (G-CSF) is a glycoprotein family shown neuroprotective effect in models of nerve damage. we evaluated the protective effects of G-CSF, conditioned media from DPSCs (DPSCs-CM) and conditioned media from transfected DPSCs with plasmid encoding G-CSF (DPSC-CMT) on SH-SY5Y exposed to CoCl2 as a model of hypoxia-induced neural damage. Materials and Methods: SH-SY5Y exposed to CoCl2 were treated with DPSCs-CM, G-CSF, simultaneous combination of DPSCs-CM and G-CSF and finally DPSC-CMT. Cell viability and apoptosis were determined by resazurin (or lactate dehydrogenase (LDH) assay alternatively) and propidium iodide (PI) staining. Western blot analysis was performed to detect changes in apoptotic protein levels. The interleukin-6 and interleukin-10 IL6/IL10 levels were measured with Enzyme-Linked Immunosorbent Assay (ELISA). Results: DPSCs-CM and G-CSF were able to significantly protect SH-SY5Y against neural cell damage caused by CoCl2 according to resazurin and LDH analysis. Also, the percentage of apoptotic cells decreased when SH-SY5Y were treated with DPSCs-CM and G-CSF simultaneously. After transfection of DPSCs with G-CSF plasmid, DPSC-CMT could significantly improve the protection. The amount of β-catenin, cleaved PARP and caspase-3 were significantly decreased and the expression of survivin was considerably increased when hypoxic SH-SY5Y treated with DPSCs-CM plus G-CSF according to Western blot. Decreased level of IL-6/IL-10, which exposed to CoCl2, after treatment with DPSCs-CM indicated the suppression of inflammatory mediators. Conclusion: Combination therapy of G-CSF and DPSCs-CM improved the protective activity.

Abstract
Previous studies have found an association between HLA-B*1502 allele and lamotrigine-induced Stevens-Johnson syndrome (SJS)/ toxic epidermal necrosis (TEN) spectrum in Han Chinese populations. This study aims to investigate the association between HLA-B*1502 and lamotrigine- or phenytoin- induced SJS/TEN in an Iranian population. The medical records of twenty-eight lamotrigine-induced SJS/TEN patients and twenty-five lamotrigine-tolerant controls as well as eight phenytoin-induced SJS/TEN and twelve phenytoin-tolerant controls were extracted between March 2013 and March 2019 from the university hospitals in Mashhad, Iran. The presence of HLA-B*1502 allele was determined using real-time polymerase chain reaction (PCR). Among lamotrigine-induced patients with SJS/TEN, 11 (39.3%) patients tested positive for the HLA-B*1502 while only 3 (12.0%) of the lamotrigine-tolerant controls tested positive for this allele. The risk of lamotrigine-induced SJS/TEN was significantly higher in patients with HLA-B*1502, with an odds ratio (OR) of 4.74 [95% confidence interval (CI) 1.14-19.73, p = 0.032]. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of HLA-B*1502 for lamotrigine-induced SJS/TEN was 39.29%, 88.00%, 78.57% and 56.41%, respectively. The HLA-B*1502 allele was present in 2 (25.0%) of phenytoin-induced SJS/TEN cases and 5 (41.7%) of the phenytoin-tolerant controls tested positive for HLA-B*1502 allele. The risk of phenytoin-induced SJS/TEN was not higher in the patients with HLA-B*1502 (OR = 0.467 [95% confidence interval (CI) 0.065-3.34, p = 0.642]). Lamotrigine-induced SJS/TEN is associated with HLA-B*1502 allele in an Iranian population but this is not the case for phenytoin-induced SJS/TEN.

Abstract
Background Skeletal development and its cellular function are regulated by various transcription factors. The T-box (Tbx) family of transcription factors have critical roles in cellular differentiation as well as heart and limbs organogenesis. These factors possess activator and/or repressor domains to modify the expression of target genes. Despite the obvious effects of Tbx20 on heart development, its impact on bone development is still unknown. Methods To investigate the consequence by forced Tbx20 expression in the osteogenic differentiation of human mesenchymal stem cells derived from adipose tissue (Ad-MSCs), these cells were transduced with a bicistronic lentiviral vector encoding Tbx20 and an enhanced green fluorescent protein. Results Tbx20 gene delivery system suppressed the osteogenic differentiation of Ad-MSCs, as indicated by reduction in alkaline phosphatase activity and Alizarin Red S staining. Consistently, reverse transcription-polymerase chain reaction analyses showed that Tbx20 gain-of-function reduced the expression levels of osteoblast marker genes in osteo-inductive Ad-MSCs cultures. Accordingly, Tbx20 negatively affected osteogenesis through modulating expression of key factors involved in this process. Conclusion The present study suggests that Tbx20 could inhibit osteogenic differentiation in adipose-derived human mesenchymal stem cells.

Abstract
Background Mesenchymal stem cells (MSCs) are attractive choices in regenerative medicine and can be genetically modified to obtain better results in therapeutics. Bone development and metabolism are controlled by various factors including microRNAs (miRs) interference, which are small non-coding endogenous RNAs. Methods In the current study, the effects of forced miR-148b expression was evaluated on osteogenic activity. Human bone marrow-derived mesenchymal stem cells (BM-MSCs) were transduced with bicistronic lentiviral vector encoding hsa-miR-148b-3p or -5p and the enhanced green fluorescent protein. Fourteen days post-transduction, immunostaining as well as Western blotting were used to analyze osteogenesis. Results Overexpression of miR-148b-3p increased the osteogenic differentiation of human BM-MSCs as demonstrated by anenhancement of mineralized nodular formation and an increase in the levels of osteoblastic differentiation biomarkers, alkaline phosphatase and collagen type I. Conclusions Since lentivirally overexpressed miR-148b-3p increased osteogenic differentiation capability of BM-MSCs, this miR could be applied as a therapeutic modulator to optimize bone function.

Abstract
BACKGROUND Genetic heterogeneity and consanguineous marriages make recessive inherited hearing loss in Iran the second most common genetic disorder. Only two reported pathogenic variants (c.323G>C, p.Arg108Pro and c.419A>G, p.Tyr140Cys) in the S1PR2 gene have previously been linked to autosomal recessive hearing loss (DFNB68) in two Pakistani families. We describe a segregating novel homozygous c.323G>A, p.Arg108Gln pathogenic variant in S1PR2 that was identified in four affected individuals from a consanguineous five generation Iranian family. METHODS Whole exome sequencing and bioinformatics analysis of 116 hearing loss-associated genes was performed in an affected individual from a five generation Iranian family. Segregation analysis and 3D protein modeling of the p.Arg108 exchange was performed. RESULTS The two Pakistani families previously identified with S1PR2 pathogenic variants presented profound hearing loss that is also observed in the affected Iranian individuals described in the current study. Interestingly, we confirmed mixed hearing loss in one affected individual. 3D protein modeling suggests that the p.Arg108 position plays a key role in ligand receptor interaction, which is disturbed by the p.Arg108Gln change. CONCLUSION In summary, we report the third overall mutation in S1PR2 and the first report outside the Pakistani population. Furthermore, we describe a novel variant that causes an amino acid exchange (p.Arg108Gln) in the same amino acid residue as one of the previously reported Pakistani families (p.Arg108Pro). This finding emphasizes the importance of the p.Arg108 amino acid in normal hearing and confirms and consolidates the role of S1PR2 in autosomal recessive hearing loss.

Abstract
BACKGROUND Joubert syndrome (JS) is a clinically and genetically heterogeneous group of rare neurodevelopmental disorder characterised by peculiar midbrain-hindbrain malformation, known as the "molar tooth" sign. JS can manifest a broad range of signs and symptoms. The most common features of JS are hypotonia, ataxia, developmental delay/intellectual disability, abnormal eye movements, and neonatal breathing abnormalities. To date, 29 genes have been shown to cause JS. METHODS We employed whole-genome single nucleotide polymorphism genotyping in a group of Iranian families with JS and Sanger sequencing of a known mutation associated with JS located in a single homozygous regions shared by affected members of the families. RESULTS Homozygosity mapping uncovered a shared ∼2.2-Mb run of homozygosity on chromosome 8q21.3-q22.1 encompassing the known JS-causing TMEM67 gene. Sanger sequencing of a known mutation (NM_153704.5: c.725A>G; p.Asn242Ser) in TMEM67 identified from studying another Iranian family using whole-exome sequencing confirmed the presence of the homozygous mutation in 22 affected members of 12 nuclear families. "Molar tooth" sign of brain magnetic resonance imaging, moderate-to-severe neurodevelopmental delay, and abnormal eye movements were the most common features of affected individuals. In addition, liver disease, seizure, behavioural abnormalities, failure to thrive, and kidney disease were observed variably in some of the patients. CONCLUSION We propose that Asn242Ser is a founder mutation in the Iranian population, which might explain a significant proportion of JS cases from eastern Iran. Therefore, screening for this variant should be considered for genetic testing in Iranian patients with JS. In addition, this finding is important for developing population-specific genetic testing in Iran.

Abstract
BACKGROUND Characterization of the molecular basis of phenylketonuria (PKU) in North-east of Iran has been accomplished through the analysis of 62 unrelated chromosomes from 31 Iranian PKU patients. METHODS Phenylalanine hydroxylase (PAH) gene mutations have been analyzed by direct DNA sequencing exons 6, 7, 10 and 11. RESULTS A mutation detection rate of 74% was achieved. Eleven different mutations were found, with the most frequent mutation, IVS10-11G>A, accounting for 19% of Khorasan-Razavi PKU alleles. Ten mutations (R176X, E280K, IVS11+1G>C, S231P, Q383X, R243X, I224T, E390G, R252W and P281L) represent the rest PKU chromosomes. One novel mutation, Q383X in the homozygote form was identified which is located in the catalytic domain (residues143-410). CONCLUSION With this high detection rate of mutations in North-east of Iran, new strategy for carrier testing could be DNA sequencing of these four exons. The other exons and boundaries will be studied only when either one or no mutations are detected in the initial screen.

Abstract
The herbicide paraquat causes lung injury that is believed to be oxygen-radical mediated. To further characterize this injury and explore new methods of preventing it, we used the spin-trapping agent N-tert-butyl-alpha-phenylnitrone (PBN) to identify the paraquat radical in lung tissue and to reduce the injury resulting from the subsequent generation of reactive oxygen species. The formation of a paraquat free radical by guinea pig lung was detected under anaerobic conditions by electron paramagnetic resonance spectrometry. Infused (25, 50, or 100 mg/kg) into guinea pig lungs (perfused at constant flow with Krebs solution containing 4% bovine serum albumin and ventilated with 95% O2-5% CO2), paraquat produced dose-dependent increases in peak airway pressure (Paw), mean pulmonary arterial perfusion pressure (Ppa), and wet-to-dry (W/D) lung weight ratio. At 100 mg/kg, paraquat increased Paw by 589.6 +/- 59.8% (mean +/- SE, n = 8) and W/D ratio from 5.33 +/- 0.07 to 6.29 +/- 0.11 (P less than 0.001). Pulmonary vascular leak index increased from 0.40 +/- 0.09 to 1.96 +/- 0.45 (P less than 0.02), without changes in pulmonary microvascular pressure. Perfusate concentrations of thromboxane B2 and 6-ketoprostaglandin F1 alpha increased, but indomethacin did not reduce the injury. PBN (2.3 mM) markedly attenuated all evidence of lung injury, which was also reduced by catalase, mannitol, ethanol, and vitamin E.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We investigated the effects of vasoactive intestinal peptide (VIP) in the feline pulmonary vascular bed under conditions of controlled pulmonary blood flow when pulmonary vascular tone was at base-line levels and when vascular resistance was elevated. Under base-line conditions, VIP caused small but significant reductions in lobar arterial pressure without affecting left atrial pressure. Decreases in lobar arterial pressure in response to VIP were greater and were dose related when lobar vascular resistance was increased by intralobar infusion of U 46619, a stable prostaglandin endoperoxide analogue. Acetylcholine and isoproterenol also caused significant decreases in lobar arterial pressure under base-line conditions, and responses to these agents were enhanced when lobar vascular tone was elevated. Moreover, when doses of these agents are expressed in nanomoles, acetylcholine and isoproterenol were more potent than VIP in decreasing lobar arterial pressure. Responses to VIP were longer in duration with a slower onset than were responses to acetylcholine or isoproterenol. Pulmonary vasodilator responses to VIP were unchanged by indomethacin, atropine, or propranolol. The present data demonstrate that VIP has vasodilator activity in the pulmonary vascular bed and that responses are dependent on the existing level of vasoconstrictor tone. These studies indicate that this peptide is less potent than acetylcholine or isoproterenol in dilating the feline pulmonary vascular bed and that responses to VIP are not dependent on a muscarinic or beta-adrenergic mechanism or release of a dilator prostaglandin.

Abstract
The effects of synthetic platelet-activating factor (PAF) on guinea pig lung were examined in isolated lungs perfused with platelet-free Krebs-Ringer solution. When PAF (1 microgram) was injected into the pulmonary artery (PA), it markedly increased airway pressure (maximal increase, 84.7%) and moderately raised PA pressure (maximal increase, 22.8%). The same dose also provoked a massive (29-fold) release of thromboxane B2 (TXB2), the stable metabolite of TXA2, into the perfusate, beginning before the increases in airway and PA pressures. The concentration of 6 keto-PGF1 alpha, the stable metabolite of prostacyclin, also increased (to 5 times control levels) about 70 s after peak release of TXB2. Indomethacin completely blocked TXB2 release, reduced the magnitude of airway pressure increase by 79%, and shortened its duration, as well as the duration of the PA pressure rise. Larger concentrations of PAF (3 and 10 micrograms) produced even greater increments in airway and PA pressures, but these were only moderately attenuated by indomethacin. Also, PAF increased extravascular lung water, as evidenced by increases in wet/dry lung weight and lung/body weight ratios. In a concentration of 0.1 microgram, PAF had no effects on airway or PA pressures, nor did it stimulate TXB2 or 6-keto-PGF1 alpha release. Lyso-PAF was similarly ineffective. We conclude that PAF induces airway constriction, pulmonary hypertension, and pulmonary edema in guinea pig lung independently of platelets. These effects are associated with stimulated synthesis of TXA2, but the mechanisms of their production remain to be determined.

Abstract
Vasoactive intestinal peptide (VIP), a potent systemic vasodilator, was recently identified in nerve fibers within the pulmonary arterial wall of cats and other mammals. We have investigated the smooth muscle relaxant action of VIP on isolated strips of kitten pulmonary artery that were placed in a 5-ml bath and precontracted with prostaglandin endoperoxide (PGH2) analogue. The action of VIP was compared with that of acetylcholine, isoproterenol, and prostaglandin E1 (PGE1). The effectiveness of VIP as a relaxant of pulmonary artery, measured as maximal relaxation and expressed in weight equivalents, was 29.9 +/- 2.0 X 10(-2) g in the presence of adrenergic and cholinergic blockers, or 28.8 +/- 4.5 X 10(-2) g in the absence of blockers. This relaxation was similar to that of acetylcholine (30.4 +/- 4.0 X 10(-2) g) and isoproterenol (26.4 +/- 2.2 X 10(-2) g), but smaller than that of PGE1 (41.1 +/- 3.7 X 10(-2) g). Judging by the EC50 or EC10 (effective concentration needed to develop 50 or 10%, respectively, of maximal relaxation), VIP was at least 40 times as potent as acetylcholine, 2,770 times as potent as isoproterenol, and 120 times as potent as PGE1, on a molar basis. The effect of VIP was unaltered in the presence of atropine, propranolol, or phenoxybenzamine in the incubation medium. The findings demonstrate the potent relaxant action of VIP in isolated pulmonary arterial strips and the independence of this action from cholinergic and adrenergic receptors. The results support the possibility that VIP may play an important role in regulating pulmonary vascular tone in kittens.

Abstract
Platelet-activating factor, a naturally occurring lipid that is released from leukocytes and alveolar macrophages, increased the flow of protein-rich lymph from the lungs and induced pulmonary edema in dogs when given in picomolar doses. The pulmonary edema was due to increased microvascular permeability, probably secondary to endothelial cell injury. These observations suggest that platelet-activating factor may be a mediator of high-permeability pulmonary edema in the "respiratory distress syndrome" complicating acute lung injury.
