Abstract Chemotherapy and radiotherapy adversely affect spermatogenesis, a consequence that is particularly relevant to young men who have yet to establish families. The harmful effects of chemotherapy on spermatogenesis are variable, depending on the type and dosage of chemotherapeutic agents used. The current study assessed the effect of cancer therapy on sperm DNA fragmentation by Comet assay. Sperm DNA fragmentation was evaluated in cured cancer patients. The results showed a significant relationship between chemotherapy and double-stranded and single-stranded sperm DNA fragmentation.
 
 

Abstract The majority of ncRNAs are known as long non-coding RNAs (lncRNAs) whose length exceeds 200 nucleotides. H19, a lncRNA, is the transcription product of the H19 gene, an oncogene in breast cancer, and is highly expressed in cancer tissues compared with normal tissues. The expression level of H19 is associated with the oncogenesis, proliferation, invasion, metastasis, and drug resistance of breast cancer. H19 expression levels were detected in breast cancer plasma using qRT-Real-Time PCR assay in 50 breast cancer samples and 50 healthy control samples. The results showed that the expression of this gene in both the tissue and the plasma of patients increased compared to that of healthy individuals.
