Molecular Mechanisms and Biomarkers Associated with Chemotherapy-Induced AKI.

Acute kidney injury (AKI) is a life-threatening condition characterized by a rapid and transient decrease in kidney function. AKI is part of an array of conditions collectively defined as acute kidney diseases (AKD). In AKD, persistent kidney damage and dysfunction lead to chronic kidney disease (CKD) over time. A variety of insults can trigger AKI; however, chemotherapy-associated nephrotoxicity is increasingly recognized as a significant side effect of chemotherapy. New biomarkers are urgently needed to identify patients at high risk of developing chemotherapy-associated nephrotoxicity and s

ER-mitochondria tethering and its signaling: A novel therapeutic target in breast cancer.

Communication between the endoplasmic reticulum (ER) and mitochondria through mitochondria-associated ER membranes (MAMs) is assisted by tethering proteins and signaling pathways, manifesting the dynamic exchange of lipids, calcium, and signaling molecules. However, dysregulation of tethering and signaling proteins contributes to the progression of breast cancer (BC). Abnormal MAM structures and altered ER-mitochondrial tethering impair mitochondrial functions and thereby drive BC progression. Altered mitochondrial dynamics, often characterized by dysregulated dynamin-related protein 1 (Drp1)

Picropodophyllin inhibits the growth of pemetrexed-resistant malignant pleural mesothelioma via microtubule inhibition and IGF-1R-, caspase-independent pathways.

BackgroundAcquired pemetrexed resistance leads to treatment interruption in patients with malignant pleural mesothelioma (MPM).

The Role of Cullin-RING Ligases in Striated Muscle Development, Function, and Disease.

The well-orchestrated turnover of proteins in cross-striated muscles is one of the fundamental processes required for muscle cell function and survival. Dysfunction of the intricate protein degradation machinery is often associated with development of cardiac and skeletal muscle myopathies. Most muscle proteins are degraded by the ubiquitin-proteasome system (UPS). The UPS involves a number of enzymes, including E3-ligases, which tightly control which protein substrates are marked for degradation by the proteasome. Recent data reveal that E3-ligases of the cullin family play more diverse and c

Repurposing drugs in oncology (ReDO)-selective PDE5 inhibitors as anti-cancer agents.

Selective phosphodiesterase 5 inhibitors, including sildenafil, tadalafil and vardenafil, are widely-used in the treatment of erectile dysfunction and pulmonary arterial hypertension. They are also well-known as examples of successful drug repurposing in that they were initially developed for angina and only later developed for erectile dysfunction. However, these drugs may also be effective cancer treatments. A range of evidentiary sources are assessed in this paper and the case made that there is pre-clinical and clinical evidence that these drugs may offer clinical benefit in a range of can

The role of EMT-related lncRNA in the process of triple-negative breast cancer metastasis.

Triple-negative breast cancer (TNBC) is the most malignant and fatal subtype of breast cancer, which has characterized by negativity expression of ER, PR, and HER2. Metastasis is the main factor affecting the prognosis of TNBC, and the process of metastasis is related to abnormal activation of epithelial-mesenchymal transition (EMT). Recent studies have shown that long non-coding RNA (LncRNA) plays an important role in regulating the metastasis and invasion of TNBC. Therefore, based on the metastasis-related EMT signaling pathway, great efforts have confirmed that LncRNA is involved in the mol

Short-chain acyl post-translational modifications in cancers: Mechanisms, roles, and therapeutic implications.

Post-translational modifications (PTMs) play a pivotal role in epigenetic regulation and are key pathways for modulating protein functionality. PTMs involve the covalent attachment of distinct chemical groups, such as succinyl, crotonyl, and lactyl, at specific protein sites, which alter protein structure, function, stability, and activity, ultimately influencing biological processes. Recently, metabolically derived short-chain acylation modifications (with acyl groups containing fewer than six carbon atoms) have been progressively identified, such as butyrylation, succinylation, crotonylation
