SARS-CoV-2 Infection during Delivery Causes Histopathological Changes in the Placenta.

Background: SARS-CoV-2 can damage human placentas, leading to pregnancy complications, such as preeclampsia and premature birth. This study investigates the histopathological changes found in COVID-19-affected placentas.

Materials And Methods: This study included 23 placentas from patients with active COVID-19 during delivery and 22 samples from patients without COVID-19 infection in their medical history.

High MAL2 expression predicts shorter survival in women with triple-negative breast cancer.

Introduction: Due to its lack of conventional surface receptors, triple-negative breast cancer (TNBC) is inherently resistant to most targeted therapies. MAL2 overexpression prompts endocytosis, conferring resistance to novel therapeutics. This study explores the role of MAL2 and PD-L1 in TNBC patients' prognosis.

Mechanisms of SARS-CoV-2 Placental Transmission.

The widespread occurrence of SARS-CoV-2 infections and the diverse range of symptoms have placed significant strain on healthcare systems worldwide. Pregnancy has also been affected by COVID-19, with an increased risk of complications and unfavorable outcomes for expectant mothers. Multiple studies indicate that SARS-CoV-2 can infiltrate the placenta, breach its protective barrier, and infect the fetus.

TOLLIP Protein Expression Predicts Unfavorable Outcome in Renal Cell Carcinoma.

Resistance to systemic therapy is one of the hallmarks of renal cell carcinoma (RCC). Recently, TOLLIP has emerged as a possible driver of autophagy and chemoresistance. We explored the relationship between primary and metastatic RCC tumor characteristics, patient survival, and TOLLIP expression.

The prognostic role of p53 and its correlation with CDK9 in urothelial carcinoma.

Purpose: The mutation of p53 is considered a pivotal step in bladder cancer pathogenesis. Recently, distinct interactions between p53 and CDK9, a transcription regulator, have been described. In this work, we explored the prognostic role of p53 expression and evaluated its associations with CDK9 in urothelial carcinoma.

The Role of Inflammatory Cytokines in the Pathogenesis of Colorectal Carcinoma-Recent Findings and Review.

The inflammatory process plays a significant role in the development of colon cancer (CRC). Intestinal cytokine networks are critical mediators of tissue homeostasis and inflammation but also impact carcinogenesis at all stages of the disease. Recent studies suggest that inflammation is of greater importance in the serrated pathway than in the adenoma-carcinoma pathway.

The Prognostic Role of CDK9 in Bladder Cancer.

Introduction: Most patients with urothelial carcinoma are diagnosed with non-invasive tumors, but the prognosis worsens with the progression of the disease. Overexpression of cyclin-dependent kinase 9 has been recently linked to increased cancer proliferation, faster progression, and worse prognosis. However, some cancers seem to contradict this rule.

CDK9 inhibitors in multiple myeloma: a review of progress and perspectives.

Currently, multiple myeloma is not yet considered a curable disease. Despite the recent advances in therapy, the average patient lifespan is still unsatisfactory. Recently, CDK9 inhibitors emerged as a suitable agent to overcome resistance and prolong survival in patients with poor diagnoses.

Current Challenges in Targeting Tumor Desmoplasia to Improve the Efficacy of Immunotherapy.

Desmoplasia is crucial for the development, progression and treatment of immune-resistant malignancies. Targeting desmoplasia-related metabolic pathways appears to be an interesting approach to expand our stock of disposable anti-tumor agents. CXCL12/CXCR4 axis inhibition reduces fibrosis, alleviates immunosuppression and significantly enhances the efficacy of PD-1 immunotherapy.

CDK9: Therapeutic Perspective in HCC Therapy.

CDK9 is an important cell-cycle control enzyme essential in transcription, elongation, and mRNA maturation. Overexpression of CDK9 has been reported in several diseases, including acute lymphoblastic leukemia, chronic lymphocytic leukemia, and malignant melanoma. Recent research revealed that CDK9-inhibitors have a major impact on the induction of apoptosis in hepatocellular carcinoma (HCC) cell lines.
