Summary: This study found that hypoxia in the adipose-tumour microenvironment promotes lipid uptake in cancer cells, leading to increased proliferation. Additionally, hypoxia alters the metabolome of adipocytes and drives proliferation of non-malignant cells.

Summary: Novel cupric-tirapazamine [Cu(TPZ)2]-liposomes were developed as an effective hypoxia-targeted therapeutic, which potentiated radiotherapy in a three dimensional (3D) prostate cancer (PCa) model. The highest loading efficiency was obtained at neutral pH, and enhanced drug loading was achieved upon decreasing the lipid:complex molar ratio.

Summary: Prostate cancer is the most commonly diagnosed cancer in men, and finding new prognostic biomarkers and potential therapeutic targets is crucial. Calcium signaling is involved in the progression of prostate cancer and the development of treatment resistance, with calcium channels playing a significant role in these processes. Modulating these calcium channels through pharmacological means has been suggested as a practical approach.

Summary: Conflicting results have been found in the literature regarding the association between serum lipid levels and prostate cancer. This study found lower LDL and total cholesterol levels in patients with prostate cancer at diagnosis, with no significant differences between risk groups. Low LDL cholesterol and low total cholesterol serum levels seem to be associated with prostate cancer at diagnosis.

Summary: The survival and proliferation of prostate cancer cells in hypoxic conditions are regulated by the mitochondrial protein CPT1A. Knockdown of CPT1A reduces cell viability, clonogenicity, and sphere formation, while overexpression increases proliferation. CPT1A may contribute to PCa aggressiveness by regulating cell survival in hypoxic conditions.

Summary: The study found that ZNF384 is significantly overexpressed in breast cancer and promotes breast cancer metastasis by regulating ZEB1 expression and inducing an epithelial and mesenchymal-like phenotype. Additionally, ZNF384 may be a target of miR-485-5p, and ZEB1 can up-regulate ZNF384 expression by repressing miR-485-5p expression. These findings provide evidence for the prognostic and therapeutic potential of ZNF384 in breast cancer patients.

Summary: In this study, a series of dinitrobenzamide mustards (DNBM) based on the PR-104A hypoxia-selective prodrug were designed and synthesized. Various leaving groups and the introduction of a carboxylic acid group were explored to investigate the biological performance of the DNBM constructs. The results showed that the DNBM constructs were tolerant to modifications without substantially degrading their cytotoxic potential.

Summary: Prostate cancer (PCa) is a common male malignancy with unclear progression mechanisms. This study found that NRP1, highly expressed in PCa, was associated with poor prognosis in PCa patients. Functionally, NRP1 depletion inhibited PCa cell proliferation and migration, while NRP1 overexpression promoted these processes. Mechanistically, NRP1 was regulated by HIF1 alpha and interacted with EGFR, leading to EGFR phosphorylation and activation of the AKT signaling pathway, promoting PCa progression. Additionally, the NRP1 inhibitor EG01377 inactivated the EGFR/AKT signaling axis and suppressed PCa progression.

Summary: The study showed that reduced expression of DAPK1 in PCa patients promoted stem cell-like characteristics of PCa cells by activating ZEB1, through the Hippo/YAP signaling pathway. Overexpression of DAPK1 inhibited tumor growth of PCa and repressed the expression of ZEB1, YAP, and TAZ in the tumor tissues of PCa mice.

Summary: In this study, new dendrimers multi-branched molecules based on the sequence of AaTs-1 were designed and synthesized, and they showed higher inhibitory effects on the proliferation of U87 cells compared to AaTs-1. The newly designed molecules exerted their effects by enhancing the phosphorylation of ERK1/2 and AKT, as well as increasing p53 expression. In particular, AaTs-1-4B also affected the migration of U87 cells.

Summary: Research has found that the voltage gated calcium channel CaV1.3 is increased in prostate cancer patients undergoing androgen deprivation therapy (ADT). Increased CaV1.3 isoforms promote resistance to ADT by upregulating store operated calcium entry (SOCE) and enhancing the proliferation and survival of castrate resistant prostate cancer cells.

Summary: This study investigates the subcellular localization of Aβ fibrils in transgenic mouse models and human brain tissue of Alzheimer's disease (AD). Results show the accumulation of Aβ fibrils in intralysosomal lipofuscin granules in mice and undigested material in enlarged lipofuscin granules in human cortical biopsies. However, no intraneuronal accumulations of Aβ fibrils were detected in the examined samples.

Summary: This article reviews the latest data on the adjuvant and neoadjuvant use of tyrosine kinase inhibitors, with a focus on their benefits, potential challenges, and the impact of mutation variability and financial evaluations. The review finds that tyrosine kinase inhibitors often show disease-free survival benefits, but overall survival improvement remains difficult, potentially due to variability in stages and mutations. Additionally, the safety profiles of the inhibitors are acceptable, but high costs and limited accessibility pose challenges. Overall, tyrosine kinase inhibitors offer promising opportunities for tailored treatment designs.

Summary: The study investigates the role of calcium channel CaV1.3 in androgen-resistant prostate cancer. The results show that the gene expression of CaV1.3 increases during androgen deprivation, along with the expression of androgen receptor and neuron-specific enolase. However, in the prostate cancer model used, CaV1.3 has no significant impact on store release and calcium entry. These findings are important for understanding altered calcium handling in androgen-resistant prostate cancer and developing therapeutic drugs targeting CaV1.3.

Summary: In the fight against cancer, the appearance of resistant cancer stem cells (CSCs) is a major obstacle for therapeutic strategies using cisplatin. Altered Ca2+ signaling, which is essential for various cellular processes, including proliferation and survival, has been linked to CSC functions and therapy resistance. Understanding the molecular mechanisms linking Ca2+ to cisplatin-induced resistance and CSC behaviors could lead to alternative therapeutic strategies.

Calcium signaling, which regulates various cellular functions, has been implicated in cancer development. However, there is limited information on the role of calcium signaling in cancer drug resistance. This review discusses the potential value of targeting calcium signaling to overcome cancer resistance to therapeutic drugs.

Summary: CD20 monoclonal antibodies have a strong ability to quickly kill B cells using different mechanisms. However, the assessment of killing is difficult. This study shows that common cytometry protocols involving centrifugation can miss important parts of the killing effect of drugs. Alternative methods are proposed to assess fast target cell killing in vitro, avoiding centrifugation or based on survival comparison or counting beads, which are applicable to B cell lines and primary tumor cells.

Summary: Metastatic uveal melanomas show high resistance to existing treatments. By conducting a kinome-wide CRISPR-Cas9 knockout screen, we identified the LKB1-SIK2 module as a factor restraining tumorigenesis. Loss of LKB1 enhances cell proliferation and survival by inhibiting SIK2 and upregulating SLC8A1, leading to increased levels of intracellular calcium and mitochondrial reactive oxygen species. Furthermore, a combination of an SLC8A1 inhibitor and a mitochondria-targeted antioxidant demonstrates enhanced cell death efficacy in LKB1- and SIK2-negative uveal melanoma cells.
