Summary: Researchers constructed a D-A type-based NIR-II fluorophore with mitochondria targeting, which demonstrated both photothermal effect and photodynamic performance. They further fabricated nanodots with DSPE-mPEG for in vivo experiments, achieving strong NIR-II fluorescence tracing of tumors and impressive NIR-II image-guided photodynamic therapy and photothermal therapy.

Summary: Aptamers, short oligonucleotide sequences with selective binding abilities, have shown promise in improving controlled and accurate delivery of photosensitizers into tumor sites for enhanced photodynamic therapy. Modification of aptamers onto PSs or nanocarriers enables specific recognition and binding to tumor cells, resulting in superior therapeutic efficiency. The development of aptamer-targeted platforms for tumor therapy holds potential for synergistic treatment modalities like PDT, photothermal therapy, and chemotherapy.

Summary: Much progress has been made in subcellular targeted therapy of cancer by attacking disease cell's mitochondria. Mitochondrial dysfunction controls key metabolic changes and is related to tumor invasion, proliferation, tumorigenesis, and metastasis. Supramolecular metal-organic frameworks (MOFs) can be targeted to the tumor's mitochondria selectively and disrupt cancer cells' metabolic processes. Mitochondria-targeted MOFs (mitoMOFs) have the potential to revolutionize targeted therapy and improve therapeutic outcomes with minimal side-effects.

Summary: A nucleus-targeted enzyme prodrug nanocomposite, assembled from β-cyclodextrin-lysine (CL), catalase (CAT), Pt(iv) and chlorin e6 (Ce6), was developed for self-augmenting cascade photo-chemo therapy of tumors. It can effectively transport through the cytoplasm and accumulate in the nucleus, thereby significantly inhibiting tumor growth and lung metastasis.

Summary: One of the most challenging problems in treating glioblastoma (GBM) is its highly infiltrative nature. Researchers have found that using tetramethylrhodamine methyl ester (TMRM) as a photosensitizer in combination with photodynamic therapy (PDT) can target GBM cells, inducing mitochondrial damage and cell death, making it a potential direction for clinical translation.

Summary: Small-intestinal neuroendocrine tumors (SI-NETs) have a higher prevalence and worse prognosis in male patients. This study found that mesenteric metastasis and fibrosis were more common in men than women. The risk of mesenteric metastasis in women increased around menopause. The expression of estrogen receptor alpha and androgen receptor was observed in primary tumors and mesenteric metastases.

Summary: The study aimed to enhance the expression of somatostatin type-2 receptors (SSTR2) using valproic acid (VPA) for peptide receptor radionuclide therapy (PRRT). VPA significantly increased SSTR2 expression in vitro, but in vivo, increased tumor uptake of [Lu-177]Lu-DOTATATE was not caused by SSTR2 upregulation but rather by other mechanisms such as increased radiotracer circulation time and renal toxicity.

Summary: This study investigates the chemosensitizing effect of different epi-drugs when combined with gemcitabine in pancreatic cancer. The results show that VPA combined with gemcitabine significantly reduces tumor size and activates the immune system. These findings provide a strong rationale for the application of this combination therapy in pancreatic cancer patients.

Summary: In this study, the antitumor effect of IFN-beta combined with gemcitabine in pancreatic cancer was investigated. It was found that the combination treatment enhanced the antitumor effect and had immunomodulatory effects. However, in mouse experiments, the change in tumor size with the combination treatment was not significant.

Summary: The treatment of pancreatic neuroendocrine neoplasms (PNEN) is challenging due to metastasis at diagnosis and resistance to treatment in some patients. This study explores the role of stromal fibroblasts in the growth of PNEN and their response to the mTOR inhibitor everolimus. The findings suggest that fibroblasts in the tumor microenvironment of PNEN could be a promising therapeutic target.

Summary: The aim of this study was to develop an open-source and reproducible digital quantitative analysis method for evaluating somatostatin receptor subtype 2a staining in pancreatic neuroendocrine tumors and growth hormone-secreting pituitary adenomas. The results showed that this method had a strong correlation with the widely used semi-quantitative immunoreactivity score and could also evaluate the biochemical response to somatostatin receptor ligands.

Summary: By blocking the IFNGR signaling pathway, S100A9 is upregulated in T cells and acts as a novel suppressor of graft-versus-host disease (GVHD) while preserving graft-versus-leukemia (GVL) effects. In both mouse models of allo-HSCT and xenogeneic human peripheral blood mononuclear cell transplantation, overexpression of S100A9 or administration of anti-IFNGR antibody improved GVHD without compromising GVL and reduced T-cell trafficking to GVHD target organs.

Summary: Cabergoline (CAB) is an off-label medical therapy for acromegaly, but it is overshadowed by first-generation somatostatin receptor ligands like octreotide (OCT). In this study, OCT was found to be slightly more effective than CAB in inhibiting growth hormone (GH) secretion in vitro. Additionally, the response to CAB treatment was shown to be better in GH/prolactin (PRL) co-secreting tumors.

Summary: Glucocorticoid stress hormones are essential for physiology and exert numerous actions via binding to the glucocorticoid receptor (GR). Relacorilant is a selective GR antagonist being evaluated for the treatment of endogenous Cushing's syndrome. This study compared the effects of relacorilant and the non-selective antagonist mifepristone, showing that relacorilant has potent antagonistic effects on GR signaling and prevents anti-inflammatory effects of glucocorticoids.

Summary: Mesenteric metastases in small intestinal neuroendocrine tumors (SI-NETs) are associated with mesenteric fibrosis (MF). Proteomics-based analysis found differential protein abundance primarily in the stromal compartment of mesenteric metastases of SI-NET patients with MF. The differentially abundant proteins included collagen and proteoglycans associated with profibrotic extracellular matrix dysregulation and signaling pathways. COL12A1 and C9 were confirmed to have significantly higher expression in MF mesenteric metastases. This study provides insights into new signaling pathways involved in MF development.

Summary: This study found that DNA methylation and histone modifications are associated with SST2 expression in SI-NETs. DNA methylation levels and H3K27me3 levels were lower in SI-NETs compared to normal tissue, and there was a negative correlation between SST2 mRNA expression level and DNA methylation. However, the role of histone modifications in SI-NETs remains unclear.

Summary: In vitro experiments showed that HDAC inhibitors had the desired effects. However, there was no significant increase in tumoral DOTA-TATE uptake after HDAC inhibitor treatment in NCI-H69 tumor-bearing animals. The expression levels of tumoral SSTR2 mRNA and/or protein were significantly upregulated after treatment with certain inhibitors. There was a significant inverse correlation between HDAC3 and SSTR2 expression in the studied cell lines.
