Within the endoplasmic reticulum (ER), GRP78 functions as a chaperone protein, showcasing a range of important functions. Cellular survival is impeded by the stress-induced consequence. Cancer cell expression of cell surface GRP78 (CS-GRP78) is significantly elevated by a combination of stressors, including ER stress, chronic psychological and nutritional stress, hypoxia, chemotherapy, radiation therapy, and drug resistance. Furthermore, CS-GRP78 is correlated with a more aggressive form of cancer and reduced responsiveness to anti-cancer therapies, signifying it as a significant therapeutic target. Experimental data highlight the possibility that targeting CS-GRP78 with anti-GRP78 monoclonal antibodies (Mab) and incorporating further treatments could potentially reverse chemotherapy, radiotherapy, or targeted therapy resistance in solid tumors, consequently boosting therapeutic outcomes. Recent data on CS-GRP78's contribution to the development of resistance to cancer treatments, and the potential benefits of using anti-GRP78 Mab in combination with other therapies for particular patient groups will be reviewed in this article. Our limited grasp of CS-GRP78 regulation in human studies remains a crucial limitation in the development of effective CS-GRP78-targeted therapies. Accordingly, further investigation is essential to integrate these potential therapies into the realm of clinical practice.

Analyzing post-mortem brain tissue is paramount to understanding cell types, their connections, and subcellular structures down to the molecular level within the central nervous system, critically important for advancing our knowledge of the many brain diseases. Immunostaining with fluorescent dyes is a key method, enabling high-resolution, three-dimensional imaging of multiple structures simultaneously. Formalin-preserved brain samples, while plentiful, frequently encounter limitations in research due to several conditions that complicate the usage of human brain tissue within high-resolution fluorescence microscopy.
For immunofluorescence analysis of perfusion- and immersion-fixed post-mortem human brain tissue, this study introduces a novel clearing strategy, human Clear Lipid-exchanged Acrylamide-hybridized Rigid Imaging / Immunostaining / In situ hybridization-compatible Tissue-hYdrogel (hCLARITY). Specificity is paramount in hCLARITY, which minimizes off-target labeling, enabling highly sensitive stainings of human brain sections. These sensitive stainings facilitate super-resolution microscopy, providing unprecedented visualization of pre- and postsynaptic compartments. Furthermore, the hallmarks of Alzheimer's disease were maintained through the hCLARITY procedure, and crucially, conventional 33'-diaminobenzidine (DAB) or Nissl stainings are compatible with this method. The multifaceted nature of hCLARITY is exemplified by its capacity to utilize more than 30 high-performing antibodies, facilitating the destaining and subsequent restaining of the same tissue section. This characteristic is vital in multiple labeling experiments, for instance, in advanced super-resolution microscopy techniques.
Through a holistic utilization of hCLARITY, one can conduct investigations into the intricate workings of the human brain, obtaining resolution on a sub-diffraction scale, alongside high sensitivity. Thus, its potential is considerable for the investigation of localized morphological variations, such as those seen in neurodegenerative diseases.
Through its comprehensive approach, hCLARITY provides researchers with the capacity to study the human brain with extreme sensitivity, reaching the sub-diffraction resolution limit.
