Background: Despite many efforts to discover the important role of the autophagy process in the pathogenesis of colorectal cancer (CRC), the exact involved molecular mechanism still remains to be elucidated. Recently, a limited number of studies have been employed to discover the impact of autophagy genes’ variants on the development and progression of CRC. Here, we evaluated the association between two single‐nucleotide polymorphisms (SNPs) in the main components of the autophagy genes,ATG16L1rs2241880, andATG5rs1475270, and the CRC risk in an Iranian population.Methods: During this investigation, a total of 369 subjects, including 179 CRC patients and 190 non‐cancer controls have been genotyped using Tetra‐primer amplification refractory mutation system‐polymerase chain reaction (TP‐ARMS‐PCR) method.Result: The results demonstrated that the T allele of theATG16L1rs2241880 was significantly associated with the increased risk of CRC in the studied population (OR 1.64, 95% CI: 1.21–2.22,p = 0.0015). Moreover,ATG16L1rs2241880 TT genotype increased the susceptibility to CRC (OR 3.31, 95% CI: 1.64–6.69,p = 0.0008). Furthermore, a significant association was observed under the recessive and dominant inheritance models (p = 0.0015 andp = 0.017, respectively). No statistically significant differences were found in theATG5rs1475270 alleles and genotypes between the cases and controls.Conclusion: The results of the present study may be helpful concerning the risk stratification in CRC patients based on the genotyping approach of autophagy pathways and emphasize the need for further investigations among different populations and ethnicities to refine our conclusions.

Schwartz-Jampel syndrome (SJS) is a rare autosomal recessive disorder characterized by muscle stiffness (myotonia) and chondrodysplasia. This disease is caused by biallelic loss of function mutations in the HSPG2 gene, which encodes the core protein of perlecan. This study aims to investigate causative variants in two sisters born to consanguineous Iranian parents. Both patients were presented with myotonia and a mask-like face; moreover, they showed a less common symptom, gastrointestinal bleeding, which is not typical of SJS and has only been reported in one patient. Regarding the crucial role of perlecan in vascular structure and mucosal stability, bleeding disorders could be expected in perlecan dysfunctions. In addition to the case study, a comprehensive literature review was conducted to gather information on similar genetic variants, associated clinical features, and possible disease mechanisms. Results of this study contribute to our understanding of the genetic and clinical aspects of Schwartz-Jampel syndrome, and more importantly, the manifestation of gastrointestinal bleeding in patients with Schwartz-Jampel syndrome.

This review article presents an in-depth analysis of the current state of research on receptor tyrosine kinase regulatory non-coding RNAs (RTK-RNAs) in solid tumors. RTK-RNAs belong to a class of non-coding RNAs (nc-RNAs) responsible for regulating the expression and activity of receptor tyrosine kinases (RTKs), which play a critical role in cancer development and progression. The article explores the molecular mechanisms through which RTK-RNAs modulate RTK signaling pathways and highlights recent advancements in the field. This include the identification of potential new RTK-RNAs and development of therapeutic strategies targeting RTK-RNAs. While the review discusses promising results from a variety of studies, encompassing in vitro, in vivo, and clinical investigations, it is important to acknowledge the challenges and limitations associated with targeting RTK-RNAs for therapeutic applications. Further studies involving various cancer cell lines, animal models, and ultimately, patients are necessary to validate the efficacy of targeting RTK-RNAs. The specificity of ncRNAs in targeting cellular pathways grants them tremendous potential, but careful consideration is required to minimize off-target effects, the article additionally discusses the potential clinical applications of RTK-RNAs as biomarkers for cancer diagnosis, prognosis, and treatment. In essence, by providing a comprehensive overview of the current understanding of RTK-RNAs in solid tumors, this review emphasizes their potential as therapeutic targets for cancer while acknowledging the associated challenges and limitations.
