Article Abstract
RAS proteins, as the most frequently mutated oncoproteins in human cancers, drive tumor proliferation, metastasis, and therapeutic resistance. Recent studies have revealed that ubiquitination dynamically regulates the stability, membrane localization, and signaling transduction of RAS proteins, profoundly impacting their oncogenic functions. A series of ubiquitination sites, E3 ligases, deubiquitinases, and regulatory proteins are involved in RAS ubiquitination. We also analyze the heterogeneity of ubiquitination patterns across distinct RAS isoforms (KRAS4A, KRAS4B, NRAS, and HRAS) and their functional disparities in cancers. Targeting the ubiquitination pathway offers novel strategies to overcome RAS proteins. Future research should integrate protein structure analysis and high-throughput screening to develop specific ubiquitination modulators and explore combination RAS ubiquitination targeting strategies with RAS inhibitors or immunotherapy, aiming to overcome RAS-driven malignant phenotypes.

Background: Trials of neoadjuvant chemoimmunotherapy (chemoIO) have changed the standard of care for resectable nonsmall cell lung cancer (NSCLC). This study characterizes the outcomes of off-trial patients who received treatment with neoadjuvant chemoIO.
Methods: The authors analyzed records of patients with stage IB-III NSCLC who received neoadjuvant chemoIO with an intent to proceed to surgical resection at three US academic institutions.

Rat sarcoma virus oncogene (RAS) proteins are of crucial oncogenic proteins and are involved in several essential intracellular processes. The RAS protein has an intrinsic metal binding site for Mg, which is important for the conformational stability of the active site. Recently, it was reported that a second metal ion binding site, located further from the active site in HRAS (Harvey RAS homolog), binds Ca with millimolar affinity.

Introduction: Ovarian cancer (OC) is a common malignant tumor of the female reproductive system and is usually found at an advanced stage. However, the treatment of OC with conventional the efficacy of surgery and chemotherapy is limited. Brusatol (BRU) is a unique nuclear factor erythroid 2-related factor 2 (Nrf2) pathway inhibitor with significant anti-cancer effects.

Objectives: Non-small cell lung cancer (NSCLC) is associated with poor prognosis, with 30% of patients diagnosed at an advanced stage. Mutations in the and genes are important prognostic factors for NSCLC, and targeted therapies can significantly improve survival in these patients. Although tissue biopsy remains the gold standard for detecting gene mutations, it has limitations, including invasiveness, sampling errors due to tumor heterogeneity, and poor reproducibility.

Background/aims: Endoplasmic reticulum (ER) stress in hepatocytes plays a causative role in alcohol-associated liver disease (ALD). The incomplete inhibition of ER stress by targeting canonical ER stress sensor proteins suggests the existence of noncanonical ER stress pathways in ALD pathology. This study aimed to delineate the role of RAB25 in ALD and its regulatory mechanism in noncanonical ER stress pathways.
