Transcriptomic Profile of Perineural Invasion in Prostate Cancer Identifies Prognostic Gene Signatures.

Prostate cancer is a common malignancy among men worldwide, with various histopathologic features that influence its progression and prognosis. One such feature is perineural invasion (PNI), which has been associated with aggressive disease. In this retrospective study, we analyzed genomic alterations associated with PNI in patients who underwent radical prostatectomy.

Impact of Cribriform Pattern on Progression-Free Survival After Radical Prostatectomy in Gleason Score 8-10 Prostate Cancer.

Background: Although extensive research highlights the detrimental effect of cribriform pattern 4 (CP4) on survival in non-high-risk prostate cancer (PC), its prognostic significance in high-risk PC is not well understood. Methods: The individual patient data from the The Cancer Genome Atlas (TCGA) database following radical prostatectomy was retrospectively examined. A predefined statistical analysis was conducted to evaluate the potential association between CP4 and progression-free survival (PFS).

The G protein-coupled receptor GPR89A is a novel potential therapeutic target to overcome cisplatin resistance in NSCLC Calu1 cells.

Lung cancer is the most frequently diagnosed cancer type worldwide and is characterised by its high metastatic potential. Standard therapy for nonsmall cell lung cancer (NSCLC) cases includes chemotherapy with the platinum-based chemotherapeutic agent cisplatin. Although lung cancer cases respond well to cisplatin at the beginning of treatment, ~ 60% develop chemotherapy resistance during this process.

Clinical Outcomes and Genomic Alterations in Gleason Score 10 Prostate Cancer.

This study aimed to determine whether GS 10 PC has distinct clinical outcomes from other "high-risk" cancers (i.

Molecular Alterations Associated with Histologically Overt Stromal Response in Patients with Prostate Cancer.

Prostate cancer has substantial heterogeneity in clinical outcomes and therapeutic responses, posing challenges in predicting disease progression and tailoring treatment strategies. Recent studies have highlighted the potential prognostic value of evaluating the tumor microenvironment, including the presence of a histologically overt stromal response (HOST-response) characterized by peri-glandular stromal changes and architectural distortions. This retrospective study examined patient records from The Cancer Genome Atlas database to identify genomic alterations associated with the HOST-response in prostate cancer.

Unveiling Off-Target Mutations in CRISPR Guide RNAs: Implications for Gene Region Specificity.

The revolutionary CRISPR-Cas9 technology has revolutionized genetic engineering, and it holds immense potential for therapeutic interventions. However, the presence of off-target mutations and mismatch capacity poses significant challenges to its safe and precise implementation. In this study, we explore the implications of off-target effects on critical gene regions, including exons, introns, and intergenic regions.

Histologically Overt Stromal Response and the Risk of Progression after Radical Prostatectomy for Prostate Cancer.

Purpose: Given the variable clinical course of prostate cancer and the limitations of current prognostic factors, this study was conducted to investigate the impact of a histologically overt stromal response (HOST-response) to prostate cancer on clinical outcomes after radical prostatectomy.

Methods: This retrospective analysis utilized The Cancer Genome Atlas (TCGA) to evaluate data from individuals with a confirmed diagnosis of prostate cancer who underwent radical prostatectomy and had available pathology slides. These slides were assessed for the presence of a HOST-response, similar to desmoplasia.

Ponatinib and STAT5 Inhibitor Pimozide Combined Synergistic Treatment Applications Potentially Overcome Drug Resistance via Regulating the Cytokine Expressional Network in Chronic Myeloid Leukemia Cells.

Chronic myeloid leukemia (CML) is a clonal myeloproliferative hematological disease characterized by the chimeric breakpoint-cluster region/Abelson kinase1 (BCR::ABL1) oncoprotein; playing a pivotal role in CML molecular pathology, diagnosis, treatment, and possible resistance arising from the success and tolerance of tyrosine kinase inhibitor (TKI)-based therapy. The transcription factor STAT5 constitutive signaling, which is influenced by the cytokine signaling network, triggers BCR::ABL1-based CML pathogenesis and is also relevant to acquired TKI resistance. The unsuccessful therapeutic approaches targeting BCR::ABL1, in particular third-line therapy with ponatinib, still need to be further developed with alternative combination strategies to overcome drug resistance.

Investigating the effects of PTEN mutations on cGAS-STING pathway in glioblastoma tumours.

Background: PTEN is a tumour suppressor gene and well-known for being frequently mutated in several cancer types. Loss of immunogenicity can also be attributed to PTEN loss, because of its role in establishing the tumour microenvironment. Therefore, this study aimed to represent the link between PTEN and cGAS-STING activity, a key mediator of inflammation, in tumour samples of glioblastoma patients.

The Role of Endoplasmic Reticulum Stress in Gastroesophageal Reflux Disease Symptoms and Treatment.

Decreased circulating microRNA-21 and microRNA-143 are associated to pulmonary hypertension.

Background: Pulmonary arterial hypertension (PAH) is characterized by maladaptation of pulmonary vasculature which is leading to right ventricular hypertrophy and heart failure. miRNAs play a crucial role in the regulation of many diseases such as viral infection, cancer, cardiovascular diseases, and pulmonary hypertension (PH). In this study, we aimed to investigate the expression pattern of eight human plasma miRNAs (hsa-miR-21-3p, hsa-miR-143- 3p, hsa-miR-138-5p, hsa-miR-145-3p, hsa-miR-190a, hsa-miR-204-3p, hsamiR-206, hsa-miR-210-3p) in mild-to-severe PH patients and healthy controls.

CHRM3-Associated miRNAs May Play a Role in Bile Acid-Induced Proliferation of H508 Colon Cancer Cells.

Background: It was well defined that proliferative effects of bile acids on colon epithelium are through interaction with muscarinic-3 receptors. Recently, microRNA emerged as an important regulator of gene expression and has been implicated in pathogenesis of many malignancies. However, the interaction of CHRM3 and microRNAs and their potential effects on colon carcinogenesis remains to be elucidated.

Expression analysis of novel long non-coding RNAs for invasive ductal and invasive lobular breast carcinoma cases.

Aim: Long non-coding RNAs (LncRNAs) serve as important regulatory molecules of gene expression and protein functionality at multiple biological levels, and their deregulation plays a key role in tumorigenesis including in breast cancer metastasis. Therefore, in this study, we aim to compare the expression of novel lncRNAs in the landscape of invasive ductal carcinoma (IDC) and invasive lobular (ILC) carcinoma of breast.

Main Methods: We have designed an in-silico approach to find the lncRNAs that regulate the breast cancer.

Functional roles of miR-625-5p and miR-874-3p in the progression of castration resistant prostate cancer.

Aims: Androgen receptor (AR) signaling is important in normal prostate and prostate tumor tissues. Thus, the new therapeutic strategies targeting ARs may also be important for treatment of prostate cancer (PC) and its biology. The studies have shown that miRNAs to be dysregulated in PC progression.

Combination of dasatinib and okadaic acid induces apoptosis and cell cycle arrest by targeting protein phosphatase PP2A in chronic myeloid leukemia cells.

Chronic myeloid leukemia (CML) is a cancer type of the white blood cells and because of BCR-ABL translocation it results in increased tyrosine kinase activity. For this purpose, dasatinib is the second-generation tyrosine kinase inhibitor that is used for inhibition of BCR-ABL. Effectively and safetly, dasatinib has been used for imatinib-intolerant/resistant CML patients.

Association of the sEH gene promoter polymorphisms and haplotypes with preeclampsia.

Background: The epoxyeicosatrienoic acids (EETs) have antihypertensive, anti-inflammatory, and organ protective properties and their circulation levels are related to hypertension, diabetes mellitus, cardiovascular diseases, and preeclampsia. Soluble epoxide hydrolase (sEH) catalyses the degradation of EETs to less biologically active dihydroxyeicosatrienoic acids. Here, we sequenced the promoter region of to investigate the association between promoter sequence alterations that we thought to affect the expression levels of the enzyme and preeclampsia (PE).
