Cellular homeostasis is governed by the precise expression of genes that control the translation, localization, and termination of proteins. Oftentimes, environmental and biological factors can introduce mutations into the genetic framework of cells during their growth and division, and these genetic abnormalities can result in malignant transformations caused by protein malfunction. For example, p53 is a prominent tumor suppressor protein that is capable of undergoing more than 300 posttranslational modifications (PTMs) and is involved with controlling apoptotic signaling, transcription, and the DNA damage response (DDR). In this review, we focus on the molecular mechanisms and interactions that occur between p53, the HECT E3 ubiquitin ligases WWP1, SMURF1, HECW1 and HERC2, and other oncogenic proteins in the cell to explore how irregular HECT-p53 interactions can induce tumorigenesis.

Osteoarthritis (OA) is the most widespread joint disorder worldwide. It is a major cause of lower limb mobility issues in the elderly. With the ongoing aging of the global population and the increasing prevalence of obesity, the disease burden associated with OA is expected to rise significantly.

Feline mammary carcinoma (FMC) is the most prevalent reproductive tumor in queens and is characterized by aggressive metastatic progression and short survival. Protein phosphorylation is a crucial process in cell regulation, with dysregulation linked to cancer progression, including human breast cancer. Although phosphoproteins have emerged as diagnostic and predictive markers in human breast cancer, knowledge remains limited on their role in FMC.

Osteoarthritis (OA) is a common joint disease, and chondrocyte extracellular matrix (ECM) degradation was closely associated with its progression. This study investigated the regulatory mechanisms of ECM degradation during OA development. A rat model of OA was established by anterior cruciate ligament transection (ACL-T) and interleukin-1 beta (IL-1β)-stimulated rat chondrocytes were used to simulate OA in vitro.

CMTM (CKLF-like MARVEL transmembrane domain-containing) proteins play pivotal roles in tumorigenesis and cancer progression across various malignancies. However, their expression profiles and regulatory mechanisms in distinct subtypes of breast cancer remain largely undefined. In this study, we systematically analyzed the expression of all nine CMTM family members across major molecular subtypes of breast cancer, including Luminal A, Luminal B, HER2-positive (HER2+), and triple-negative breast cancer (TNBC).

The HECW2 gene encodes a HECT (homologous to E6-AP carboxy terminus)-type E3 ubiquitin ligase that plays a critical role in neurodevelopment. Pathogenic variants in HECW2 are associated with a neurodevelopmental disorder characterized by hypotonia, seizures, and absent language (NDHSAL; OMIM #617268), typically inherited in an autosomal dominant pattern. However, recent evidence suggests that some variants in HECW2 gene may cause the disease with autosomal recessive inheritance.
