Analysis of microRNAs in Exosomes of Breast Cancer Patients in Search of Molecular Prognostic Factors in Brain Metastases. Int J Mol Sci 2022; 23:ijms23073683.

Abstract
Brain metastases are the most severe tumorous spread during breast cancer disease. They are associated with a limited quality of life and a very poor overall survival. A subtype of extracellular vesicles, exosomes, are sequestered by all kinds of cells, including tumor cells, and play a role in cell-cell communication. Exosomes contain, among others, microRNAs (miRs). Exosomes can be taken up by other cells in the body, and their active molecules can affect the cellular process in target cells. Tumor-secreted exosomes can affect the integrity of the blood-brain barrier (BBB) and have an impact on brain metastases forming. Serum samples from healthy donors, breast cancer patients with primary tumors, or with brain, bone, or visceral metastases were used to isolate exosomes and exosomal miRs. Exosomes expressed exosomal markers CD63 and CD9, and their amount did not vary significantly between groups, as shown by Western blot and ELISA. The selected 48 miRs were detected using real-time PCR. Area under the receiver-operating characteristic curve (AUC) was used to evaluate the diagnostic accuracy. We identified two miRs with the potential to serve as prognostic markers for brain metastases. Hsa-miR-576-3p was significantly upregulated, and hsa-miR-130a-3p was significantly downregulated in exosomes from breast cancer patients with cerebral metastases with AUC: 0.705 and 0.699, respectively. Furthermore, correlation of miR levels with tumor markers revealed that hsa-miR-340-5p levels were significantly correlated with the percentage of Ki67-positive tumor cells, while hsa-miR-342-3p levels were inversely correlated with tumor staging. Analysis of the expression levels of miRs in serum exosomes from breast cancer patients has the potential to identify new, non-invasive, blood-borne prognostic molecular markers to predict the potential for brain metastasis in breast cancer. Additional functional analyzes and careful validation of the identified markers are required before their potential future diagnostic use.

Abstract
Background Cytochrome c is an intermembrane mitochondrial protein that is released to the bloodstream following mitochondrial injury. Methods and results We developed an electrochemiluminescence immunoassay to measure cytochrome c in human and rat plasma, which showed high sensitivity with broad dynamic range (2-1200 ng/mL in humans and 5-500 ng/mL in rat) and high assay reproducibility (inter-assay coefficient <6% in humans and <10% in rat). In patients after blunt trauma, plasma cytochrome c directly correlated with injury severity. In rats after cardiac resuscitation, plasma cytochrome c inversely correlated with survival and responsiveness to mitochondrial protective interventions. Conclusions The cytochrome c assays herein presented have high sensitivity, wide dynamic range, and high reproducibility well suited for biomarker of mitochondrial injury.

Abstract
Non-small cell lung cancer has a devastating prognosis, and markers enabling a precise prediction of therapy response have long remained scarce. Better treatment monitoring would allow an individual's more effective patient adjusted therapy with lesser side effects and good clinical outcomes. In the present study, we monitored the serum cytochrome c levels pre- and post-chemotherapy of non-small cell lung cancer patients. Using highly sensitive enzyme-linked immunosorbent assay, we evaluated cytochrome c levels in serum of 100 non-small cell lung cancer and 100 healthy controls. We observed about threefold lower serum cytochrome c level in newly diagnosed non-small cell lung cancer patients than healthy individuals. Patients in advanced stages and grade 3 histological differentiation showed significantly low level of serum cytochrome c, and the lower levels were associated with worse survival outcome of non-small cell lung cancer patients. In addition, serum cytochrome c level was observed to be more than 13-fold higher after first cycle of conventional chemotherapy, wherein patients with higher level of serum cytochrome c before any therapy showed better response to chemotherapy in terms of significantly higher level of serum cytochrome c after first cycle of chemotherapy than patients with low level of serum cytochrome c at the time of diagnosis. Detection of serum cytochrome c levels at the time of diagnosis may be useful in suggesting disease severity and prognosis of the non-small cell lung cancer patients. Monitoring of serum cytochrome c might also serve as a sensitive apoptotic marker in vivo reflecting chemotherapy-induced cell death burden in patients with non-small cell lung cancer.

Abstract
The balance between cell death and cell survival is a tightly controlled process, especially in terminally differentiated cells, such as the cardiomyocyte. Accumulating data support a role for cardiomyocyte apoptosis in the development of several cardiac diseases, including the transition from hypertensive compensatory hypertrophy to heart failure. This review briefly summarizes the status of the knowledge regarding the death-survival balance of cardiomyocytes in the context of hypertensive heart disease. Several molecular and cellular aspects as well as the most relevant pathophysiological implications are presented. Moreover, diagnosis tools under development and the possibilities for pharmacological intervention are also examined.

Abstract
The biochemical cascades associated with cell death after traumatic brain injury (TBI) involve both pro-survival and pro-apoptotic proteins. We hypothesized that elevated cerebrospinal fluid (CSF) Bcl-2 and cytochrome C (CytoC) levels over time would reflect cellular injury response and predict long-term outcomes after TBI. Cerebrospinal fluid Bcl-2 and CytoC levels were measured for 6 days after injury for adults with severe TBI (N=76 subjects; N=277 samples). Group-based trajectory analysis was used to generate distinct temporal biomarker profiles that were compared with Glasgow Outcome Scale (GOS) and Disability Rating Scale (DRS) scores at 6 and 12 months after TBI. Subjects with persistently elevated temporal Bcl-2 and CytoC profiles compared with healthy controls had the worst outcomes at 6 and 12 months (P≤0.027). Those with CytoC profiles near controls had better long-term outcomes, and those with declining CytoC levels over time had intermediate outcomes. Subjects with Bcl-2 profiles that remained near controls had better outcomes than those with consistently elevated Bcl-2 profiles. However, subjects with Bcl-2 values that started near controls and steadily rose over time had 100% good outcomes by 12 months after TBI. These results show the prognostic value of Bcl-2 and CytoC profiles and suggest a dynamic apoptotic and pro-survival response to TBI.

Abstract
Cerebrospinal fluid (CSF) contains a dynamic and complex mixture of proteins, which can reflect a physiological and pathological state of the central nervous system. In our present study, we show CSF protein patterns from patients with the two most frequent subtypes of sporadic Creutzfeldt-Jakob disease (sCJD) defined by the codon 129 genotype (MM, MV, and VV) and the protease-resistant form of prion protein (type 1 and type 2). The densitometric analysis of 2D gels showed up-regulation of 27 and down-regulation of 3 proteins in the MM-sCJD as well as the up-regulation of 24 proteins in the VV-sCJD as compared to nondemented control. Almost 40% of sCJD specific regulated proteins in CSF are involved in glucose metabolism, regardless of the codon 129 polymorphism. The increase in CSF levels of lactate dehydrogenase (LDH), glucose-6-phosphate isomerase (G6PI), and fructose-bisphosphate aldolase A (ALDOA) were validated on a larger group of sCJD patients including three possible codon 129 polymorphism carriers and three control groups consisting of nondemented, neurological cases as well as patients suffering from Alzheimer's disease or vascular dementia. Subsequently, the abundance of these glycolytic enzymes in the brain as well as their cellular localization were determined. This study demonstrates for the first time the implication of G6PI in prion-induced pathology as well as its cellular translocalization in sCJD. The identification of sCJD-regulated proteins in CSF of living symptomatic patients in our study can broaden our knowledge about pathological processes occurring in sCJD, as they are still not fully understood.

Abstract
The
physical manifestations of aging reflect a loss of homeostasis that effects
molecular, cellular and organ system functional capacity. As a sentinel
homeostatic pathway, changes in apoptosis can have pathophysiological
consequences in both aging and disease. To
assess baseline global apoptosis balance, sera from 204 clinically
normal subjects had levels of sFas (inhibitor of apoptosis), sFasL
(stimulator of apoptosis), and total cytochrome c (released from cells
during apoptosis) measured. Serum levels of sFas were significantly higher
while sFasL and cytochrome c levels were lower in men compared to women.
With increasing age there was a decrease in apoptotic markers (cytochrome
c) and pro-apoptotic factors (sFasL) and an increase in anti-apoptotic
factors (sFas) in circulation. The observed gender differences are
consistent with the known differences between genders in mortality and
morbidity. In a separate cohort, subjects with
either breast (n = 66) or prostate cancer (n = 38) exhibited significantly
elevated sFas with reduced sFasL and total cytochrome c regardless of age.
These markers correlated with disease severity consistent with tumor
subversion of apoptosis. The shift toward less global apoptosis with
increasing age in normal subjects is consistent with increased incidence of
diseases whose pathophysiology involves apoptosis dysregulation.

Abstract
Early assessment of cancer response to the treatment is of great importance in clinical oncology. Most antitumor drugs, among them DNA topoisomerase (topo) inhibitors, target nuclear DNA. The aim of the present study was to explore feasibility of the assessment of DNA damage response (DDR) as potential biomarker, eventually related to the clinical response, during treatment of human leukemias. We have measured DDR as reported by activation of ATM through its phosphorylation on Ser 1981 (ATM-S1981(P)) concurrent with histone H2AX phosphorylation on Ser139 (gammaH2AX) in leukemic blast cells from the blood of twenty patients, 16 children/adolescents and 4 adults, diagnosed with acute leukemias and treated with topo2 inhibitors doxorubicin, daunomycin, mitoxantrone or idarubicin. Phosphorylation of H2AX and ATM was detected using phospho-specific Abs and measured in individual cells by flow cytometry. The increase in the level of ATM-S1981(P) and gammaH2AX, varying in extent between the patients, was observed in blasts from the blood collected one hour after completion of the drug infusion with respect to the pre-treatment level. A modest degree of correlation was observed between the induction of ATM activation and H2AX phosphorylation in blasts of individual patients. The number of the studied patients (20) and the number of the clinically non-responding ones (2) was too low to draw a conclusion whether the assessment of DDR can be clinically prognostic. The present findings, however, demonstrate the feasibility of assessment of DDR during the treatment of leukemias with drugs targeting DNA.

Abstract
PURPOSE OF REVIEW It is widely accepted that there are two principal forms of cell death, namely, necrosis and apoptosis. According to the classical view, necrosis is the major mechanism of cardiomyocyte death in cardiac diseases. RECENT DEVELOPMENTS In the past few years observations have been made showing that cardiomyocyte apoptosis occurs in diverse conditions including hypertensive heart disease, and that apoptosis may be a contributing cause of loss and functional abnormalities of cardiomyocytes in this condition. SUMMARY This review will summarize recent evidence demonstrating the potential contribution of cardiomyocyte apoptosis to heart failure in hypertensive patients. In addition, some strategies aimed to detect and prevent apoptosis of cardiomyocytes will be considered.

Abstract
The rapid development of new diagnostic procedures, the mapping of the human genome, progress in mapping genetic polymorphisms, and recent advances in nucleic acid- and protein chip technologies are driving the development of personalized therapies. This breakthrough in medicine is expected to be achieved largely due to the implementation of "lab-on-the-chip" technology capable of performing hundreds, even thousands of biochemical, cellular and genetic tests on a single sample of blood or other body fluid. Focusing on a few disease-specific examples, this review discusses selected technologies and their combinations likely to be incorporated in the "lab-on-the-chip" and to provide rapid and versatile information about specific diseases entities. Focusing on breast cancer and after an overview of single-nucleotide polymorphism (SNP)-screening methodologies, we discuss the diagnostic and prognostic importance of SNPs. Next, using Duchenne muscular dystrophy (DMD) as an example, we provide a brief overview of powerful and innovative integration of traditional immuno-histochemistry techniques with advanced biophysical methods such as NMR-spectroscopy or Fourier-transformed infrared (FT-IR) spectroscopy. A brief overview of the challenges and opportunities provided by protein and aptamer microarrays follows. We conclude by highlighting novel and promising biochemical markers for the development of personalized treatment of cancer and other diseases: serum cytochrome c, cytokeratin-18 and -19 and their proteolytic fragments for the detection and quantitation of malignant tumor mass, tumor cell turn-over, inflammatory processes during hepatitis and Epstein-Barr virus (EBV)-induced hemophagocytic lymphohistiocytosis and apoptotic/necrotic cancer cell death.

Abstract
The recognition that cardiac myocytes die by multiple mechanisms and thus substantially affect ventricular remodeling in diseased human hearts supports the concept of ongoing myocyte death in the progression of heart failure and constitutes the basis of this review. In addition, based on the pathophysiology of myocardial cell deaths, the present study emphasizes that currently methodologies, although with some inherent limitations, are available to recognize and measure quantitatively the contribution of myocyte cell death to the progression of the pathologic state of the heart. Our own studies show that application of such methodologies including modern microscopy techniques and the use of different molecular and immunohistochemical markers may generate the consensus that myocyte cell death is a quantifiable parameter in the normal and pathological human heart. The present study also demonstrates that myocyte cell death, apoptotic, oncotic or autophagic in nature, has to be regarded as an additional critical variable of the multifactorial events implicated in the alterations of cardiac anatomy and myocardial structure of the diseased human heart.
