Overexpression of CIP2A is associated with poor prognosis in multiple myeloma.

Cancerous inhibitor of protein phosphatase 2A (CIP2A), an endogenous protein phosphatase 2A (PP2A) inhibitor, has been identified as an oncoprotein in promoting cancer initiation and progression of several types of cancer. However, the expression and the role played by CIP2A in the pathogenesis of multiple myeloma (MM) remain unclear. In this study, we showed that CIP2A was overexpressed in human MM cell lines and MM patients' bone marrow tissues. Clinicopathologic analysis showed that CIP2A expression was significantly correlated with clinical stage and percent of plasma cells in bone marrow.

HMMR in human cancers: regulatory mechanism and biological function.

Hyaluronan-mediated motility receptor (HMMR), also referred to as RHAMM or CD168, has gained recognition as a multifunctional protein that mediates the transmission of extracellular matrix-derived hyaluronan (HA) signals to intracellular pathways regulating tumor growth, migration, and mitosis. Overexpression of HMMR is observed in various cancers, including head and neck squamous cell carcinoma, breast cancer, lung cancer, and prostate cancer, as well as several hematologic malignancies. This elevated expression correlates with poor prognosis, rendering it a valuable marker for survival predi

Tackling the cytokine storm in COVID-19, challenges and hopes.

The outbreak of Coronavirus disease 2019 (COVID-19) is the current world health concern, presenting a public health dilemma with ascending morbidity and mortality rates exceeding any previous viral spread, without a standard effective treatment yet. SARS-CoV-2 infection is distinguished with multiple epidemiological and pathological features, one of them being the elevated levels of cytokine release, which in turn trigger an aberrant uncontrolled response known as "cytokine storm". This phenomenon contributes to severe acute respiratory distress syndrome (ARDS), leading to pneumonia and respir

Prospects and Challenges of Lung Cancer Vaccines.

Lung cancer remains one of the most prevalent and lethal malignancies worldwide. Although conventional treatments such as surgery, chemotherapy, and radiotherapy have modestly improved patient survival, their overall efficacy remains limited, and the prognosis is generally poor. In recent years, immunotherapy, particularly immune checkpoint inhibitors, has revolutionized cancer treatment. Nevertheless, the immunosuppressive tumor microenvironment, tumor heterogeneity, and immune escape mechanisms significantly restrict the clinical benefit, which falls short of expectations. Within this contex

A Rare and Fatal Case of Hemophagocytic Lymphohistiocytosis Associated with Sarcoidosis.

BACKGROUND Sarcoidosis is a systemic inflammatory disorder characterized by a classic pathologic feature of non-caseating granulomas involving any organ system. Hemophagocytic lymphohistiocytosis (HLH) is a catastrophic cytokine surge characterized by dysregulation of the macrophage response, which can be rapidly fatal. Recognition of HLH has been increasing over the past decade. HLH can present with features of sepsis that can make the diagnosis challenging and requires high clinical suspicion. CASE REPORT We report a case of a 48-year-old African American male with a past medical history of

Targeting BRD4: Potential therapeutic strategy for head and neck squamous cell carcinoma (Review).

As a member of BET (bromodomain and extra-terminal) protein family, BRD4 (bromodomain‑containing protein 4) is a chromatin‑associated protein that interacts with acetylated histones and actively recruits regulatory proteins, leading to the modulation of gene expression and chromatin remodeling. The cellular and epigenetic functions of BRD4 implicate normal development, fibrosis and inflammation. BRD4 has been suggested as a potential therapeutic target as it is often overexpressed and plays a critical role in regulating gene expression programs that drive tumor cell proliferation, survival, mi

Crosstalk between glucocorticoid and mineralocorticoid receptors boosts glucocorticoid-induced killing of multiple myeloma cells.

The glucocorticoid receptor (GR) is a crucial drug target in multiple myeloma as its activation with glucocorticoids effectively triggers myeloma cell death. However, as high-dose glucocorticoids are also associated with deleterious side effects, novel approaches are urgently needed to improve GR action in myeloma. Here, we reveal a functional crosstalk between GR and the mineralocorticoid receptor (MR) that plays a role in improved myeloma cell killing. We show that the GR agonist dexamethasone (Dex) downregulates MR levels in a GR-dependent way in myeloma cells. Co-treatment of Dex with the
