Point mutations of the P53 gene, human hepatocellular carcinoma and aflatoxins [PDF]

open access: yes, 1993
The tumor suppressor p53 exerts important protective functions towards DNA-damaging agents. Its inactivation by allelic deletions or point mutations within the P53 gene as well as complex formation of wildtype p53 with cellular or viral proteins is a ...

Single‐Cell and Spatial Transcriptomic Profiling of Penile Squamous Cell Carcinoma Reveals Dynamics of Tumor Differentiation and Immune Microenvironment

open access: yesAdvanced Science, EarlyView.
This study uses single‐nucleus RNA sequencing and spatial transcriptomics to investigate penile squamous cell carcinoma (PSCC). It reveals that PSCC tumor cells mimic normal penile epithelium differentiation, independent of HPV status. The Tum_1 subtype shows basal stem‐like characteristics and promotes invasiveness. HPV‐positive basal stem‐like tumors

The State of High‐Resolution Imaging of the Human Inner Ear: A Look Into the Black Box

open access: yesAdvanced Science, EarlyView.
High‐resolution imaging of the cochlea is challenged by numerous unique aspects of this organ, where sensorineural cells, crucial for hearing, are too small for conventional modalities like magnetic resonance imaging and computed tomography. This article reviews current imaging techniques, emerging technologies, and innovations aimed at improving ...

QSOX2‐Mediated Disulfide Bond Modification Enhances Tumor Stemness and Chemoresistance by Activating TSC2/mTOR/c‐Myc Feedback Loop in Esophageal Squamous Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
High QSOX2 enhances stemness, drug resistance, and metastasis of ESCC cells. QSOX2‐mediated disulfide bond modification activates mTOR/c‐Myc signaling. CAFs‐secreted IGF‐1 drives mTOR/c‐Myc/QSOX2 positive feedback loop. Combining Ebselen, rapamycin, and cisplatin induces tumor dormancy in mice.
