Here, we present a protocol to enable the capture and identification of disease-specific protein-protein interactions from native cells and tissues using chemical probes and mass spectrometry. The resulting interaction datasets are analyzed through a dedicated web-based platform to reveal dynamic network dysfunctions and pathway alterations linked to disease.

Mouse model of metabolic dysfunction-associated steatotic liver disease (MASLD) with metabolic dysfunction, hepatic gene expression changes, and liver histopathological alterations that resemble human MASLD, including fibrosis that progresses to advanced fibrosis stage 3. This model can be used in studies of MASLD pathophysiology and in pre-clinical studies of new therapies.

The material here describes a method developed to preserve the three-dimensional chromatin structure of testicular germ cells. This has been termed the three-dimensional (3D) slide method. This method improves sensitivity for detection of subnuclear structures and is applicable for immunofluorescence, DNA, and RNA fluorescence in situ hybridization (FISH).

Early stage hemodynamic dysfunction is critical to the development of kidney disease. Yet, detection methodologies are limited. Recent advances in sonography provide a noninvasive, accurate option for early detection of kidney injury. This study outlines a step-by-step, sonographic methodology for detecting kidney dysfunction using a drug-induced nephrotoxicity rat model.
FAQs
The location and nature of the disruption influence whether testosterone synthesis, sperm development, or both are impaired. Abnormal hormonal signaling may interfere with the coordination required for spermatogenesis, while damage to testicular tissue may directly affect function. Recognizing these separate but connected pathways helps clinicians interpret why endocrine and reproductive abnormalities can occur independently or together.
Several types of disturbance can interfere with testicular activity, including tissue damage, genetic conditions, infection, medications, abnormal hormonal signaling, and other disease. Because these factors may affect different biological processes, the same broad clinical problem can have different underlying explanations. Identifying the contributing pathway is therefore important for evaluating the abnormality and selecting an appropriate management strategy.
Yes. Testicular dysfunction may disrupt hormone production, sperm development, or both, so reproductive and endocrine effects do not necessarily occur in the same pattern. This distinction matters because a person may require assessment of hormonal function and sperm production as separate dimensions of testicular health. Considering both prevents evaluation from focusing on only one possible outcome.
Assessment may integrate medical history, physical examination, hormone testing, semen analysis, and imaging. The history can identify relevant disease, medication, or other contributing factors, while examination and imaging help investigate structural abnormalities. Hormone testing addresses endocrine function, and semen analysis evaluates sperm development. Using these sources together supports a more complete search for the underlying problem.
Hormone testing examines the endocrine dimension of testicular function, particularly abnormalities related to testosterone production or hormonal signaling. Semen analysis provides information about the reproductive dimension, including whether sperm development has been disrupted. Their findings may point toward impairment in one process or both, helping clinicians characterize the pattern of dysfunction rather than relying on a single measurement.
Imaging can complement medical history, examination, laboratory testing, and semen analysis by helping identify underlying structural abnormalities. Its value is greatest when clinicians need information that cannot be obtained from hormone measurements or sperm analysis alone. As part of a combined assessment, imaging contributes to linking observed reproductive or endocrine problems with possible changes in testicular structure.
In clinical medicine, evaluating testicular dysfunction supports the assessment of infertility, hypogonadism, and related health problems. In research, the topic provides a framework for studying how tissue damage, hormonal abnormalities, genetic conditions, infection, medications, and other disease affect reproductive and endocrine outcomes. It also supports investigation of longer-term endocrine consequences associated with impaired testicular function.
