Orofacial clefts (OFCs) are one of the most prevalent congenital abnormalities that affect the lip and/or palate and can cause significant growth retardation in newborns. Several studies have revealed that children with congenital defects or genetic syndromes have their own growth pattern, which may differ from that of normal children. However, during infancy and until around age two, these babies usually show a period of catch-up growth in length, weight, and head circumference for both boys and girls. It was noted out that both genders had smaller physical dimensions than normal children. In order to partially elucidate the biological mechanism affecting children with non-syndromic OFCs, this systematic review aims to assess the relative expression and localization of growth factors and their receptors in craniofacial tissues. A comprehensive literature search was carried out on May 1, 2025, using three important databases: Web of Science Core collection, PubMed, and Scopus. The search was limited to only English-language studies involving human subjects, but it was not limited by publication date. To find potentially relevant publications, specific keywords and database-specific search techniques were used. Based on predefined inclusion criteria, 20 studies were selected from a total of 191 articles following a thorough screening process. Growth factors and susceptibility to OFCs were found to be significantly correlated in the analysis of the reports of the chosen studies. Particularly, OFCs and their risk were consistently associated with fibroblast growth factor receptor ( The reviewed studies indicate a role of growth-related proteins in the pathophysiology of non-syndromic OFCs. This is demonstrated by the fact that The online version contains supplementary material available at 10.1186/s12903-026-07715-x. Show less

Cytokines are a group of immunomodulatory proteins leading to a variety of immune reactions in the human; these cytokines play a significant role in the development of appropriate immune responses against T. gondii. This study aims to reveal the association of toxoplasmosis with serum levels of IL-3, IL-17A, and IL-27 in aborted women. The blood samples of patients and controls were collected from Al-Alawiya Maternity Teaching Hospital/Baghdad/Iraq from 2019 to 2020 for detecting anti-T. gondii antibodies (IgG and IgM) and the level of interleukins by ELISA. The results of TORCH by rapid test for recurrent abortion recorded 25.3% seropositive for anti-Toxoplasma antibodies, and 31.5% seropositive for one or more cases of TORCH test (Cytomegalovirus, Rubella, and Herpes). Whereas the results for anti-T. gondii IgG and IgM antibodies were shown elevated positivity percentages by ELISA test; these percentages were 56.2% in recurrent abortion women with significant differences (P < 0.05). The results suggested that the IL-3 serum concentration of pregnant women, recurrent abortion, and recurrent abortion with toxoplasmosis was declined versus healthy women with significant differences (p < 0.05). However, the results revealed that the concentration of IL-17A in recurrent abortion, and recurrent abortion with toxoplasmosis elevated versus healthy women and pregnant women with significant difference (p < 0.05). Whereas the results indicated that the IL-27 serum concentration elevated with significant differences in recurrent abortion with toxoplasmosis group compared to healthy women, pregnant women, and recurrent abortion. Interestingly, the serum levels for IL-27 increased comparing to the levels of IL-3 and IL-17A in all groups with significant differences (P < 0.05). In conclusion, it appeared in this study that the role of IL-3, IL-17A, and IL-27 in the maternal immune response during infections can lead to abortion. Show less

Single nucleotide polymorphisms (SNPs) are predictive markers for diseases, also cytokines are undergoing genetic controls and their genetic polymorphisms have a functional role in regulating the levels of cytokine gene expression. This study aims to reveal the association of toxoplasmosis with serum levels and SNP of IL-27 in aborted women. Total, 200 blood samples of patients and controls were collected from Al-Alawiya Maternity Teaching Hospital/Baghdad/Iraq from 2019–2020 for detecting the level of IL-27 by ELISA while the allelic discrimination method was used for SNP IL-27 (rs153109). The results indicated the IL-27 serum concentration elevated with significant differences in recurrent abortion with toxoplasmosis group compared to healthy women, pregnant women, and recurrent abortion. Also, recurrent abortion had significant differences compared to healthy women and pregnant women (P<0.05). Moreover, SNP results of IL-27 showed no significant association between patients and controls. Considering the distribution of serum levels for IL-27 by SNP, it was observed that IL-27 serum levels for TT, TC, and CC genotypes elevated in the patient group versus the control group. In addition, it was observed elevation serum level of IL-27 for the genotypes TT, TC, and CC in recurrent abortion with toxoplasmosis in contrast to healthy women, pregnant women, and recurrent abortion (P<0.05). Also, in recurrent abortion, the level of IL-27 for TC, and CC genotype showed significant differences comparing to healthy and pregnant women (P<0.05). In conclusion, the level of IL-27 in recurrent abortion women with toxoplasmosis was higher than the recurrent abortion women, which may be due to the inflammatory response to toxoplasmosis. SNP of IL-27 has not represented as a risk factor in recurrent abortion women with toxoplasmosis. Show less
