Summary: NecroIr1 and NecroIr2, iridium(iii) complexes, induce necroptosis in cisplatin-resistant lung cancer cells by selectively accumulating in mitochondria and causing oxidative stress. Additionally, they interfere with cell cycle progression, leading to G0/G1 phase arrest. The combined effect of necroptosis induction and cell cycle arrest makes them potential antitumor agents against drug-resistant cancer cells.

Summary: CDKs, cyclins, and CKIs play important roles in the cell cycle regulatory machinery, and dysregulation of their expression or function can contribute to tumorigenesis. While designing CDK inhibitors to target tumor cells shows promise, the non-canonical functions of CDKs pose challenges in their application. This review aims to explore the biology of CDKs and their contribution to tumorigenesis, and discuss the pros and cons of CDK inhibition in the treatment of human cancers.

Summary: Gastric cancer is characterized by uncontrolled growth and metastasis of gastric epithelial cells, which is predominantly in adenocarcinoma form. The regulation of gastric cell growth is influenced by key cell cycle regulators, including Cyclins and Cyclin-dependent kinases (CDKs). Dysregulation of these molecules can lead to disturbances in cell cycle dynamics and the development of gastric cancer. Numerous studies have examined the roles of Cyclins and CDKs in gastric cancer, and this review aims to compile evidence of upstream regulators that activate or inhibit Cyclins and CDKs. It serves as a comprehensive resource for future studies and hypothesis generation.

Summary: In this review, the potential of cyclin-dependent kinases (CDK) as novel therapeutic targets in rheumatoid arthritis (RA) and psoriasis is evaluated. CDK inhibitors show promise due to their potential multidirectional effects on osteoclastogenesis, neutrophil apoptosis, and macrophage apoptosis, all of which play important roles in the development of joint destruction and inflammation in RA and psoriasis. However, further clinical trials are needed to assess the efficacy and safety of CDK-blocking therapy in these conditions.

Summary: Our study demonstrates the essential role of Pef1 in promoting pre-meiotic DNA replication and regulating meiotic initiation and progression through cyclin-coordinated mechanisms. Deletion of pef1 leads to defects in meiotic nuclear divisions, suppressed expression of DNA replication factors, and delayed meiotic progression, highlighting the importance of Pef1 in meiosis.

Summary: CDK11 is a kinase that controls cell proliferation by regulating transcription, RNA splicing, and the cell cycle. OTS964 is a small-molecule inhibitor that shows specificity for CDK11 in cells. The crystal structure analysis reveals that CDK11 adopts an active-like conformation when bound to OTS964. The contribution of specific amino acids to the binding of OTS964 to CDK11 was evaluated by in vitro isothermal titration calorimetry (ITC) and resistance studies in cells.

Summary: This study suggests that CDK1 and CDK4 may serve as potential prognostic biomarkers for hepatocellular carcinoma (HCC). The high expression of CDK1 and CDK4 is significantly associated with worse prognosis in HCC patients. The study also identifies transcription factors and immune cell-related markers that are correlated with CDK1 and CDK4 expression. Targeting these transcription factors combined with immunotherapy may be a promising therapeutic strategy for HCC patients with high CDK1 and CDK4 expression, especially those with hepatitis-related HCC.

Summary: This study used dual RNA-seq to investigate the transcriptional response of host and parasite in a mouse model of visceral leishmaniasis caused by Leishmania infantum and Leishmania donovani. The results showed that the host response was broadly similar in both infections, with around 10% of host differentially expressed genes varying between the two parasite species.

Summary: This study reveals the mechanism of Trypanosoma brucei rhodesiense penetration through the blood-brain barrier and causing sleeping sickness. The Cathepsin L-like cysteine peptidase and its endogenous inhibitor ICP play important roles in the infection process and regulate inflammatory responses. The results suggest that ICP helps to downregulate inflammatory responses and control the infection.

Summary: Peptidyl tRNA hydrolase (Pth) is essential for bacterial growth and contributes to the recycling of translation machinery. This study used a novel sequencing-based strategy called Cu-tRNAseq to investigate the physiological role of Pth in Mycobacterium tuberculosis (Mtb). The results showed that Pth is crucial for the turnover of peptidyl prolyl-tRNA and reducing its levels made Mtb more vulnerable to tRNA synthetase inhibitors and macrolides. These findings highlight the potential of targeting Pth as a new therapeutic approach for tuberculosis.

Summary: Despite advancements in treatment options, there is a need for new drugs to eradicate human African trypanosomiasis (HAT). In this study, potent 2,4-diaminothiazoles were developed as drug-like inhibitors against Trypanosoma brucei. Animal testing confirmed the efficacy in the hemolymphatic stage, but optimization for brain penetration did not achieve the desired in vivo efficacy due to a shift in mechanism of action. Subsequent studies identified a nonessential kinase as the target and emphasized the importance of cytotoxic drugs for HAT treatment.

Summary: In this study, we identified and validated the Plasmodium falciparum acetyl-coenzyme A synthetase (PfAcAS) as an important, druggable target. Genetic and chemical validation confirmed that mutations in PfAcAS confer resistance to two antiplasmodial compounds and that these compounds directly inhibit the enzyme. We also found that PfAcAS is essential for asexual growth and involved in the epigenetic regulation of gene expression.
