Abstract
The mitochondrial calcium uniporter (MCU) is a transmembrane protein facilitating the entry of calcium ions into mitochondria from the cell cytosol. Maintaining calcium balance is crucial for enhancing cellular energy supply and regulating cell death. The interplay of calcium balance through MCU and the sodium-calcium exchanger is known, but its regulation in the breast cancer tumor microenvironment remains elusive. Further investigations are warranted to explore MCU's potential in BRCA clinical pathology, tumor immune microenvironment, and precision oncology. Our study, employing a multi-omics approach, identifies MCU as an independent diagnostic biomarker for breast cancer (BRCA), correlated with advanced clinical status and poor overall survival. Utilizing public datasets from GEO and TCGA, we discern differentially expressed genes in BRCA and examine their associations with immune gene expression, overall survival, tumor stage, gene mutation status, and infiltrating immune cells. Spatial transcriptomics is employed to investigate MCU gene expression in various regions of BRCA, while spatial transcriptomics and single-cell RNA-sequencing methods explore the correlation between MCUs and immune cells. Our findings are validated through the analysis of 59 BRCA patient samples, utilizing immunohistochemistry and bioinformatics to examine the relationship between MCU expression, clinicopathological features, and prognosis. The study uncovers the expression of key gene regulators in BRCA associated with genetic variations, deletions, and the tumor microenvironment. Mutations in these regulators positively correlate with different immune cells in six immune datasets, playing a pivotal role in immune cell infiltration in BRCA. Notably, high MCU performance is linked to CD8 + T cells infiltration in BRCA. Furthermore, pharmacogenomic analysis of BRCA cell lines indicates that MCU inactivation is associated with increased sensitivity to specific small molecule drugs. Our findings suggest that MCU alterations may be linked to BRCA progression, unveiling new diagnostic and prognostic implications for MCU in BRCA. The study underscores MCU's role in the tumor immune microenvironment and cell cycle progression, positioning it as a potential tool for BRCA precision medicine and drug screening.

Abstract
Copper (Cu) plays a crucial and diverse function in biological systems, acting as a cofactor at numerous sites of enzymatic activity and participating in various physiological processes, including oxidative stress regulation, lipid metabolism, and energy metabolism. Similar to other micronutrients, the body regulates Cu levels to ensure homeostasis; any disruption in Cu homeostasis may result in various illnesses. Cuproptosis causes proteotoxic stress and ultimately results in cell death by the binding of Cu ions to lipid-acylated proteins during the tricarboxylic acid cycle of mitochondrial respiration. Cu is not only involved in regulatory cell death (RCD), but also in exogenous factors that induce cellular responses and toxic outcomes. Cu imbalances also affect the transmission of several RCD messages. Therefore, this article presents a thorough examination of the mechanisms involved in Cu-induced RCD as well as the role of Cu complexes in its pathophysiology.

Abstract
LSM1 is part of the cytoplasmic protein complex Lsm1-7-Pat1 and is likely involved in pre-mRNA degradation by aiding U4/U6 snRNP formation. More research is needed to uncover LSM1's potential in breast cancer (BRCA) clinical pathology, the tumor immune microenvironment, and precision oncology. We discovered LSM1 as a diagnostic marker for advanced BRCA with poor survival, using a multi-omics approach. We studied LSM1 expression across BRCA regions and its link to immune cells through various methods, including spatial transcriptomics and single-cell RNA-sequencing. We also examined how silencing LSM1 affects mitochondrial function and energy metabolism in the tumor environment. These findings were confirmed using 54 BRCA patient biopsies and tissue microarrays. Immunofluorescence and bioinformatics assessed LSM1's connection to clinicopathological features and prognosis. This study uncovers gene patterns linked to breast cancer, with LSM1 linked to macrophage energy processes. Silencing LSM1 in breast cancer cells disrupts mitochondria and energy metabolism. Spatial analysis aligns with previous results, showing LSM1's connection to macrophages. Biopsies confirm LSM1 elevation in advanced breast cancer with increased macrophage presence. To summarize, LSM1 changes may drive BRCA progression, making it a potential diagnostic and prognostic marker. It also influences energy metabolism and the tumor's immune environment during metastasis, showing promise for precision medicine and drug screening in BRCA.

Abstract
Breast cancer stands as the most prevalent and heterogeneous malignancy affecting women globally, posing a substantial health concern. Enhanced comprehension of tumor pathology and the development of novel therapeutics are pivotal for advancing breast cancer treatment. Contemporary breast cancer investigation heavily leans on in vivo models and conventional cell culture techniques. Nonetheless, these approaches often encounter high failure rates in clinical trials due to species disparities and tissue structure variations. To address this, three-dimensional cultivation of organoids, resembling organ-like structures, has emerged as a promising alternative. Organoids represent innovative in vitro models that mirror in vivo tissue microenvironments. They retain the original tumor's diversity and facilitate the expansion of tumor samples from diverse origins, facilitating the representation of varying tumor stages. Optimized breast cancer organoid models, under precise culture conditions, offer benefits including convenient sample acquisition, abbreviated cultivation durations, and genetic stability. These attributes ensure a faithful replication of in vivo traits of breast cancer cells. As intricate cellular entities boasting spatial arrangements, breast cancer organoid models harbor substantial potential in precision medicine, organ transplantation, modeling intricate diseases, gene therapy, and drug innovation. This review delivers an overview of organoid culture techniques and outlines future prospects for organoid modeling.

Abstract
The present study investigates the clinical relevance of glycolytic factors, specifically PGAM1, in the tumor microenvironment of kidney renal clear cell carcinoma (KIRC). Despite the established role of glycolytic metabolism in cancer pathophysiology, the prognostic implications and key targets in KIRC remain elusive. We analyzed GEO and TCGA datasets to identify DEGs in KIRC and studied their relationship with immune gene expression, survival, tumor stage, gene mutations, and infiltrating immune cells. We explored Pgam1 gene expression in different kidney regions using spatial transcriptomics after mouse kidney injury analysis. Single-cell RNA-sequencing was used to assess the association of PGAM1 with immune cells. Findings were validated with tumor specimens from 60 KIRC patients, correlating PGAM1 expression with clinicopathological features and prognosis using bioinformatics and immunohistochemistry. We demonstrated the expression of central gene regulators in renal cancer in relation to genetic variants, deletions, and tumor microenvironment. Mutations in these hub genes were positively associated with distinct immune cells in six different immune datasets and played a crucial role in immune cell infiltration in KIRC. Single-cell RNA-sequencing revealed that elevated PGAM1 was associated with immune cell infiltration, specifically macrophages. Furthermore, pharmacogenomic analysis of renal cancer cell lines indicated that inactivation of PGAM1 was associated with increased sensitivity to specific small-molecule drugs. Altered PGAM1 in KIRC is associated with disease progression and immune microenvironment. It has diagnostic and prognostic implications, indicating its potential in precision medicine and drug screening.

Abstract
Background: Vacuum-assisted breast biopsy (VABB) for benign breast tumor excision is a developing trend in breast surgery. The most common complication of VABB is hematoma. We assessed the efficiency of the thrombin-gelatin matrix (TGM) for hemostasis after VABB. Methods: From December 2013 to June 2017, 147 patients with breast tumors > 2 cm in size were treated with a 7-gauge ultrasound-guided EnCor EnSpire® breast biopsy system. After VABB, the TGM was applied using an iron-tube device. After injection, brief external compression for 15 min and postoperative bandage compression for approximately 12 h were applied. The medical records were reviewed and analyzed for hematoma and acute bleeding at 1 and 3 months after VABB. Results: A total of 72 patients received hemostasis via TGM, and 75 patients received hemostasis by compression. The rates of postoperative acute bleeding in the TGM group were significantly lower than those in the non-TGM group (5.5% vs. 22.7%, p = 0.003). Among patients with hematoma, there was no statistically significant difference between the two groups (25% vs. 26.7%, p = 0.85). Conclusions: This is the first cohort study to apply the TGM hemostatic matrix for post-VABB hemostasis. The TGM hemostatic matrix could be an option for patients with large breast tumors.

Abstract
BACKGROUND Patients with liver metastasis from breast cancer (LMBC) are usually offered systemic therapy. However, for those with progressive liver disease and limited extra-hepatic conditions, local liver management becomes an option. Herein we present our experience with hepatic arterial infusion chemotherapy (HAIC). PATIENTS AND METHODS From 1999 to 2018, 42 patients with LMBC, who had progressive liver metastasis after systemic therapy, were treated with HAIC. A catheter was placed angiographically into the hepatic artery and remained there for 5 consecutive days. One cycle of chemotherapy consisted of mitoxantrone, 5-fluorouracil, folinic acid, and cisplatin. This treatment was repeated at monthly intervals. The medical records were reviewed and analyzed for hepatic tumor response, progression-free survival, overall survival and adverse effects. RESULTS Complete response was observed in two patients (5%), partial response in 18 patients (43%) and stable disease in eight patients (19%). Fourteen patients (33%) had progressive disease after HAIC. The median progression-free survival and overall survival were 8.4 and 19.3 months, respectively. There was no death related to HAIC. The patients with response to the treatment had a significant survival benefit (p<0.005). CONCLUSION HAIC can be an option for those with progressive liver disease who are heavily pretreated while their extra-hepatic conditions are minimal or stable.

Abstract
A new herpesvirus-like DNA sequence (KSHV) has been recently identified in Kaposi's sarcoma (KS) from patients with AIDS and non-AIDS patients. To verify the specificity of the association of this new viral DNA with KS, a total of 155 cases of benign and malignant vascular neoplasms sharing similar histogenesis of endothelial derivation were analyzed for the presence of this KSHV sequence using the published 330-233 primers by polymerase chain reaction (PCR). The results revealed that all 17 cases of KS, both AIDS and non-AIDS, were positive for this KSHV, whereas the remaining 138 cases of vascular lesions other than KS, including 15 cases of angiosarcoma, showed negative reaction. These results confirm and extend the previous observation that this KSHV sequence is specifically associated with KS and is a reliable diagnostic marker to distinguish KS, particularly at its early stage, from other vascular lesions.

Abstract
Binding of trichloromonofluoromethane, dichlorodifluoromethane, and dichlorotetrafluoroethane was studied in aqueous 5% human albumin solution, using the partition coefficient method in sealed serum bottles. The partition coefficient and the fraction of fluorocarbons bound were highly dependent on fluorocarbon concentrations. The average binding sites per molecule of albumin were 2.17, 0.30, and 0.42 and the binding association constants were 1.11 X10-3, 1.73 X10-3, and 5.06X10-3 M-minus 1, respectively. At the lowest concentration studied, 62.3, 25.5, and 65.6% were found bound to albumin, respectively. This appears to represent the first extensive study on any gas-albumin interaction.

It was found that at the total concentration of 0.4 x 10-3 M of F 114 in the 5-percent protein solution, 50, 51 and 55% of them, respectively, were in bound form at the temperatures indicated above. The termodynamic data found for the F 114-bovine albumin interaction in the temperature range studied were: deltaG = -3.44 to -4.11 Kcal/mol. deltaS =20.40 to 20.45 e.u., and deltaH =2.23 Kcal/mol. It is postulated that the large positive entropic change associated with a sizable positive enthalpy change indicates that the breaking of iceberg water stucture and slight unfolding of albumin molecule are involved in the interaction.
