Small cell neuroendocrine cervical carcinoma is a highly aggressive tumor characterized by early metastasis, a high recurrence rate, and poor prognosis. This study represents the first instance of single-cell sequencing conducted on small cell neuroendocrine carcinoma of the cervix worldwide. Analysis of gene expression regulatory networks revealed that the transcription factor TFF3 drived up-regulation of ELF3. Furthermore, our findings indicated that the neuroendocrine marker genes and gene regulatory networks associated with small cell neuroendocrine cervical carcinoma differed from those observed in lung, small intestine, and liver neuroendocrine carcinoma within the GEO database, suggesting tissue-specific origins for these malignancies. Overall, this study addresses a significant research in understanding small cell neuroendocrine cervical carcinoma in vivo and provides valuable insights for guiding radiotherapy, chemotherapy, and targeted therapy.

Objective: This study aimed to develop a predictive model using a random forest algorithm to determine the likelihood of postoperative adhesive small bowel obstruction (ASBO) in infants under 3 months with intestinal malrotation.
Methods: A machine learning model was used to predict postoperative adhesive small bowel obstruction using comprehensive clinical data extracted from 107 patients with a follow-up of at least 24 months. The Boruta algorithm was used for selecting clinical features, and nested cross-validation tuned and selected hyper-parameters for the random forest model.

SUMOylation is a protein modification process that involves the covalent attachment of a small ubiquitin-like modifier (SUMO) to a specific lysine residue on the target protein. This modification can influence the function, localization, stability, and interactions of proteins, thereby regulating various cellular processes. Altering the SUMOylation of certain proteins is expected to be a potential approach for treating specific cancers and diseases.

The uptake of Ca by mitochondria is an important and tightly controlled process in various tissues. Even small changes in the key proteins involved in this process can lead to significant cellular dysfunction and, ultimately, cell death. In this study, we used stimulated emission depletion (STED) microscopy and developed an unbiased approach to monitor the sub-mitochondrial distribution and dynamics of the mitochondrial calcium uniporter (MCU) and mitochondrial calcium uptake 1 (MICU1) under resting and stimulated conditions.

Low-temperature injury affects normal physiological function and viability of boar sperm during cryopreservation. Small ubiquitin-like modifier (SUMO) modification of proteins after translation is related to the cell stress response but the relationship between SUMO modification and oxidative stress in freeze-thawed sperm remains unclear. A-kinase ankyrin 4 (AKAP4) and its precursor proAKAP4 are two main proteins in mammalian sperm.

Epidermal growth factor receptor (EGFR) is amongst the earliest targeted kinases by small-molecule inhibitors for the management of EGFR-positive cancer types. While a few inhibitors are granted FDA approval for clinical use, discovery of new inhibitors is still of merit to enhance ligand-binding stability and subsequent enzyme inhibition. Thus, a structure-based design approach was adopted to devise a new series of twenty-nine N3-substituted quinazolin-4-ones as type I ATP-competitive inhibitors targeting the deep hydrophobic pocket of EGFR.
