Summary: Targeting RRM1 promotes ferroptosis and affects the sensitivity of cancer cells to radiation and chemotherapy. RRM1 disrupts the activity and expression of antioxidant enzyme GPX4, leading to increased accumulation of reactive oxygen species and lipid peroxidation. Furthermore, targeting RRM1 also increases radiation-induced DNA damage and apoptotic signaling, causing crosstalk between ferroptosis and apoptosis.

Summary: The study revealed a significant correlation between the expression of MYBL2 and RRM2 in colorectal cancer (CRC), with MYBL2 playing a crucial role in CRC cell proliferation, DNA synthesis, and cell cycle progression in an RRM2-dependent manner. MYBL2 was found to directly bind to the promoter of RRM2 gene and promote its transcription during S-phase in collaboration with TAF15 and MuvB components. Combined suppression of MYBL2 and WEE1 was shown to synergistically inhibit CRC growth with low systemic toxicity in vivo, suggesting a potential novel approach for CRC treatment targeting both transcription and degradation machinery of RRM2.

Summary: Inhibiting the self-assembly of alpha-synuclein into amyloid structures is a potential therapeutic strategy for Parkinson's disease. This study identifies the essential domains/sequences involved in alpha-synuclein aggregation and tests the effectiveness of foldamer-based antagonists as potential therapeutic targets. The findings provide valuable insights into alpha-synuclein aggregation and have significant implications for the development of effective treatments for Parkinson's disease.

Summary: The study introduced a new series of bimetallic complexes with [Fe-III-(mu-OH)-M-II] cores using a stepwise synthetic approach. Characterization through various methods revealed that these complexes displayed significantly lower reduction potentials, paving the way for future studies on high valent bimetallic complexes in this scaffold.

Summary: This study demonstrates that RRM1 is essential for the growth of small-cell lung carcinoma cells, with its deletion inducing DNA damage response and reducing the number of cells in S phase cell cycle arrest. Additionally, RRM1 deletion causes overall changes in the metabolic profile of SCLC cells, revealing a potential link between tumor growth and the regulation of deoxyribonucleotide metabolism in SCLC.

Summary: The study evaluated the importance of ribonucleotide reductase regulatory subunit M2 (RRM2) in hepatocellular carcinoma (HCC) using the Cancer Genome Atlas (TCGA) database. The results showed that RRM2 overexpression was associated with worse prognosis and immune infiltrates in HCC, suggesting that RRM2 may serve as a significant molecular biomarker for HCC diagnosis and prognosis.

Summary: The 20S proteasome is composed of layered alpha and beta heptameric rings, with the alpha 7 subunit self-assembling into a homo-tetradecamer in solution. The structure of the alpha 7 double ring fluctuates considerably in solution, with the potential for insertion of homologous alpha subunits and conversion to hetero-heptameric alpha rings in the 20S proteasome.

Summary: Non-thermal plasma (NTP) enhances the anticancer effects of melatonin (MEL) in hepatocellular carcinoma (HCC) cells by promoting apoptosis, delaying cell cycle progression, and inhibiting cell invasion and migration. This mechanism is associated with the regulation of intracellular reactive oxygen species levels and ribonucleotide reductase regulatory subunit M2 expression. The findings highlight the pharmacological role of MEL and the adjuvant value of NTP in the combination therapy for HCC, with important implications for the development of new approaches for treatment.

Summary: RRM2 expression is significantly elevated in NF1-associated MPNST and high RRM2 expression correlates with poorer outcomes. Inhibition of RRM2 can suppress NF1-associated MPNST cell proliferation and promote apoptosis and S-phase arrest. Therefore, inhibiting RRM2 may be an effective strategy for treating NF1-associated MPNST.

Summary: Recent studies have highlighted the crucial role of DNA Polymerase 5 (DNA Pol 5) in replication forks, especially under stress conditions. Mutations affecting POLD1, amplifications of POLD2 and POLD3, and compromising the noncatalytic subunits of DNA Pol 5 are all closely related to cancer development and may open up avenues for novel therapies addressing replication stress.

Summary: This study found a correlation between high RRM2 expression and poor prognosis in pancreatic cancer patients, and RRM2 inhibition resulted in cell cycle arrest and/or apoptosis. These findings are expected to provide a new theoretical basis for pancreatic cancer treatment.

Summary: Enzyme-assisted posttranslational modifications (PTMs) play a major role in signaling across cellular compartments. However, the impact of nonenzymatic PTMs on cross-compartment signaling is not well understood. This study establishes a quantitative platform to assess the responsivity of compartmentalized subproteomes to nonenzymatic PTMs, revealing that a significant number of protein sensors respond in compartments of nonprimary origin or where their canonical activity is inoperative.

Summary: The study investigates the mechanism of action of dimethyl fumarate on innate immune cell toxicity, revealing that it modifies Keap1 to trigger mitochondrial-targeted neutrophil/macrophage apoptosis. Despite the importance of reactive electrophilic drugs, deconvolution of their principal targets remains difficult due to lack of genetic tractability and interference by non-specific compounds during validation.
