A comprehensive view on the apigenin impact on colorectal cancer: Focusing on cellular and molecular mechanisms.

Colon cancer (CC) is one of the most common and deadly cancers worldwide. Oncologists are facing challenges such as development of drug resistance and lack of suitable drug options for CC treatment. Flavonoids are a group of natural compounds found in fruits, vegetables, and other plant-based foods. According to research, they have a potential role in the prevention and treatment of cancer. Apigenin is a flavonoid that is present in many fruits and vegetables. It has been used as a natural antioxidant for a long time and has been considered due to its anticancer effects and low toxicity. The results of this review study show that apigenin has potential anticancer effects on CC cells through various mechanisms. In this comprehensive review, we present the cellular targets and signaling pathways of apigenin indicated to date in in vivo and in vitro CC models. Among the most important modulated pathways, Wnt/ß-catenin, PI3K/AKT/mTOR, MAPK/ERK, JNK, STAT3, Bcl-xL and Mcl-1, PKM2, and NF-kB have been described. Furthermore, apigenin suppresses the cell cycle in G2/M phase in CC cells. In CC cells, apigenin-induced apoptosis is increased by inhibiting the formation of autophagy. According to the results of this study, apigenin appears to have the potential to be a promising agent for CC therapy, but more research is required in the field of pharmacology and pharmacokinetics to establish the apigenin effects and its dosage for clinical studies.

Association between the rs7700944 polymorphism in the TIM-4 gene and rheumatoid arthritis in Zahedan, southeast Iran.

INTRODUCTION: Recently, an association between rheumatoid arthritis (RA) and the rs7700944 G>A variant in the T-cell immunoglobulin and mucin domains 4 (TIM-4) has been reported. OBJECTIVE: The present study aimed at investigating the impact of that polymorphism on susceptibility to RA in a sample of the Iranian population. PATIENTS AND METHODS: This case-control study was conducted on 120 patients with RA and 120 healthy subjects. The rs7700944 polymorphism in the TIM-4 gene was determined using tetra amplification refractory mutation system-polymerase chain reaction (T-ARMS-PCR) assay. RESULTS: No significant difference was observed regarding the rs7700944 polymorphism of the TIM-4 gene between patients with RA and normal individuals. In females, no significant association was found between the groups concerning the rs7700944 polymorphism of the TIM-4 gene. In males, the GA+AA genotype increased the risk of RA in comparison with the GG genotype (OR = 5.15, 95% CI = 1.30-20.48, P = 0.020). Furthermore the results showed that the rs7700944 A allele increased the risk of RA (OR = 4.39, 95% CI = 1.43-13.54, P = 0.009). CONCLUSION: Our results do not support an association between the rs7700944 polymorphism of the TIM-4 gene and RA. An interaction between this polymorphism and sex suggests a sex-specific association between this single nucleotide polymorphism and RA, which remains to be fully elucidated.

CD226 rs763361 (Gly307Ser) polymorphism is associated with susceptibility to rheumatoid arthritis in Zahedan, southeast Iran.

BACKGROUND: Rheumatoid arthritis (RA) is a chronic inflammatory disease with many genetic factors predisposing to disease susceptibility. The aim of the present study was to investigate the impact of CD226 rs727088 and rs763361 polymorphisms and susceptibility to RA in a sample of the Iranian population. METHODS: This case-control study was carried out on 100 patients with RA and 104 healthy subjects. The polymorphisms were determined using tetra amplification refractory mutation system-polymerase chain reaction assay. RESULTS: The rs763361 (Gly307Ser) polymorphism increased the risk of RA in codominant, dominant and recessive-tested inheritance models (odds ratio [OR] = 3.18, 95% confidence intervals [95% CI] = 1.44-7.02, P = 0.004, CC vs. TT, and OR = 1.98, 95% CI = 1.10-3.57, P = 0.023, CC vs. CT-TT, and OR = 2.61, 95% CI = 1.26-5.37, P = 0.010, CC + CT vs. TT, respectively). In addition, the rs763361 T allele increased the risk of RA (OR = 2.06, 95% CI = 1.38-3.08, P<0.001). However, no significant difference was observed among the groups regarding CD226 rs727088 polymorphism (χ2 = 3.20, P = 0.202). CONCLUSIONS: Our finding showed that CD226 rs763361, but not rs727088, gene polymorphism increased the risk of RA in a sample of the Iranian population.

Associação entre o polimorfismo rs7700944 no gene TIM-4 e artrite reumatoide em Zahedan, sudeste do Irã / Association between the rs7700944 polymorphism in the TIM-4 gene and rheumatoid arthritis in Zahedan, southeast Iran

INTRODUÇÃO: Recentemente, relatou-se uma associação entre artrite reumatoide (AR) e a variante rs7700944 G>A nos domínios imunoglobulina e mucina de células T (TIM-4). OBJETIVO: Investigar o impacto desse polimorfismo na suscetibilidade a AR em uma amostra da população iraniana. PACIENTES E MÉTODOS: Este estudo caso-controle foi conduzido em 120 pacientes com AR e 120 indivíduos saudáveis. O polimorfismo rs7700944 do gene TIM-4 foi determinado usando-se o ensaio tetra amplification refractory mutation system-polymerase chain reaction (T-ARMS-PCR). RESULTADOS: Não se observou diferença significativa quanto ao polimorfismo rs7700944 do gene TIM-4 entre os pacientes com AR e os indivíduos saudáveis. Nas mulheres, não houve associação significativa quanto ao polimorfismo rs7700944 do gene TIM-4 nos dois grupos. Nos homens, o genótipo GA+AA, em comparação ao GG, aumentou o risco para AR (OR = 5,15; IC 95% = 1,30-20,48; P = 0,020). Além disso, os resultados mostraram que o alelo rs7700944 A aumentou o risco para AR (OR = 4,39; IC 95% = 1,43-13,54; P = 0,009). CONCLUSÃO: Nossos resultados não confirmam a existência de associação entre AR e o polimorfismo rs7700944 do gene TIM-4. Uma interação entre esse polimorfismo e sexo sugere uma associação sexo-específica entre AR e esse polimorfismo de nucleotídeo único, que ainda requer elucidação.
