Short-chain fatty acids (SCFAs) produced by fermentation from prebiotics not only provide energy but also activate cell membrane receptors, thereby contributing to the maintenance of homeostasis in the human body. Recently, free fatty acid receptor 2 (FFAR2), which uses SCFAs as ligands, was found to exert oncoprotective effects on several types of neoplasia. This study examined whether SCFAs have oncoprotective effects on uterine cervical neoplasia. Immunohistochemical analysis revealed that FFAR2 was expressed in atypical cells and cancer cells of cervical neoplasia. Moreover, reverse transcription polymerase chain reaction showed that FFAR2 was expressed in a human cervical cancer cell line, HeLa. We also found that SCFAs inhibited the proliferation of HeLa cells, and a FFAR2 antagonist, GLPG0974, used to suppress the binding of SCFAs significantly restored the cell viability of HeLa cells blocked by acetic acid treatment. These results suggest that ingestion of prebiotics and the resulting production of SCFAs may play an oncoprotective role against uterine cervical neoplasia via FFAR2 expression.

Introduction: The core objective of this study was to precisely locate metastatic lymph nodes, identify potential areas in nasopharyngeal carcinoma patients that may not require radiotherapy, and propose a hypothesis for reduced target volume radiotherapy on the basis of these findings. Ultimately, we reassessed the differences in dosimetry of organs at risk (OARs) between reduced target volume (reduced CTV2) radiotherapy and standard radiotherapy.

Background: Ovarian cancers (OC) and cervical cancers (CC) have poor survival rates. Tumor-infiltrating lymphocytes (TILs) play a pivotal role in prognosis, but shared immune mechanisms remain elusive.
Methods: We integrated single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST) to explore immune regulation in OC and CC, focusing on the PI3K/AKT pathway and FLT3 as key modulators.

The cervical cell classification technique can determine the degree of cellular abnormality and pathological condition, which can help doctors to detect the risk of cervical cancer at an early stage and improve the cure and survival rates of cervical cancer patients. Addressing the issue of low accuracy in cervical cell classification, a deep convolutional neural network A2SDNet121 is proposed. A2SDNet121 takes DenseNet121 as the backbone network.

Background: Exosomes derived from cancer-associated fibroblasts (CAFs) can affect tumor microenvironment (TME) of thyroid cancer (TC). The cAMP response element binding protein 1 (CREB1) acts as a transcription factor to participate in cancer development. Currently, we aimed to explore the molecular mechanism of exosome-associated CREB1 and C-C motif chemokine ligand 20 (CCL20) in TC.
