Numerous studies have elucidated that programmed cell death plays a significant role in DOX-induced cardiotoxicity (DIC). This review summarizes several kinds of programmed cell death, including apoptosis, pyroptosis, necroptosis, autophagy, and ferroptosis. Furthermore, oxidative stress, inflammation, and mitochondrial dysfunction are also important factors in the molecular mechanisms of DIC. Besides, a comprehensive understanding of specific signal pathways of DIC can be helpful to its treatment. Therefore, the related signal pathways are elucidated in this review, including sirtuin deacetylase (silent information regulator 2 [Sir2]) 1 (SIRT1)/nuclear factor erythroid 2-related factor 2, SIRT1/Klotho, SIRT1/Recombinant Sestrin 2, adenosine monophosphate-activated protein kinase, AKT, and peroxisome proliferator-activated receptor. Heat shock proteins function as chaperones, which play an important role in various stressful situations, especially in the heart. Thus, some of heat shock proteins involved in DIC are also included. Hence, the last part of this review focuses on the therapeutic research based on the mechanisms above.</div></div>","PeriodicalId":9684,"journal":{"name":"Cell Stress & Chaperones","volume":"29 5","pages":"Pages 666-680"},"PeriodicalIF":3.3,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142342430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is still a lack of ideal therapies for promoting TEC proliferation. Heat shock protein A12A (HSPA12A) shows abundant expression in kidney in our previous studies. To investigate the role of HSPA12A in TEC proliferation after KI/R, an <em>in vitro</em> KI/R model was simulated by hypoxia (12 h) and reoxygenation (12 h) in human kidney tubular epithelial HK-2 cells. We found that, when hypoxia/reoxygenation (H/R) triggered HK-2 cell injury, HSPA12A expression was downregulated, and extracellular lactate, the readout of glycolysis, was also decreased. Loss and gain of functional studies showed that HSPA12A did not change cell viability after hypoxia but increased cell proliferation as well as glycolytic flux of HK-2 cells after H/R. When blocking glycolysis by 2-deoxy-D-glucose or oxamate, the HSPA12A promoted HK-2 cell proliferation was also abolished. Further analysis revealed that HSPA12A overexpression increased hypoxia-inducible factor 1α (Hif1α) protein expression and nuclear localization in HK-2 cells in response to H/R, whereas HSPA12A knockdown showed the opposite effects. Notably, pharmacological inhibition of Hif1α with YC-1 reversed the HSPA12A-induced increases of both glycolytic flux and proliferation of H/R HK-2 cells. Moreover, the HSPA12A increased Hif1α protein expression was not <em>via</em> upregulating its transcription but through increasing its protein stability in a Smurf1-dependent manner. The findings indicate that HSPA12A might serve as a promising target for TEC proliferation to help recovery after KI/R.</div></div>","PeriodicalId":9684,"journal":{"name":"Cell Stress & Chaperones","volume":"29 5","pages":"Pages 681-695"},"PeriodicalIF":3.3,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142342429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, sperm production occurs in the testes and is regulated by a complex series of cellular and molecular interactions. Endoplasmic reticulum (ER) stress arises when there is a deviation from or damage to the normal functions of the ER within cells. In response to this stress, a cascade of response mechanisms is activated to regulate ER stress within cells. This study aims to investigate the role of ER stress-regulated chaperones as potential biomarkers in male infertility. ER stress associated with azoospermia can manifest in cells such as spermatogonia in the testes and can impact sperm production. As a result of ER stress, the expression and activity of a variety of proteins within cells can be altered. Among these proteins are chaperone proteins that regulate the ER stress response. The sample size was calculated to be a minimum of 36 patients in each group. In this preliminary study, we measured and compared serum levels of protein disulfide-isomerase A1, protein disulfide-isomerase A3 (PDIA3), mesencephalic astrocyte-derived neurotrophic factor (MANF), glucose regulatory protein 78 (GRP78), clusterin (CLU), calreticulin (CRT), and calnexin (CNX) between male subjects with idiopathic nonobstructive azoospermia and a control group of noninfertile males. Serum PDIA1 (<em>P</em> = 0.0004), MANF (<em>P</em> = 0.018), PDIA3 (<em>P</em> < 0.0001), GRP78 (<em>P</em> = 0.0027), and CRT (<em>P</em> = 0.0009) levels were higher in the infertile group compared to the control. In summary, this study presents novel findings in a cohort of male infertile patients, emphasizing the significance of incorporating diverse biomarkers. It underscores the promising role of ER stress-regulated proteins as potential serum indicators for male infertility. By elucidating the impact of ER stress on spermatogenic cells, the research illuminates the maintenance or disruption of cellular health. A deeper understanding of these results could open the door to novel treatment approaches for reproductive conditions, including azoospermia.</p></div>","PeriodicalId":9684,"journal":{"name":"Cell Stress & Chaperones","volume":"29 5","pages":"Pages 654-665"},"PeriodicalIF":3.3,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1355814524001159/pdfft?md5=84713038e695926d42b7593588ba33b6&pid=1-s2.0-S1355814524001159-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142139422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Blames for the failures were unanimously directed at the Hsp90 inhibitors or tumors or both. However, analyses of recent cellular and genetic studies together with the Hsp90 data from the Human Protein Atlas database suggest that the vast variations in Hsp90 expression among different organs in patients might have been the actual cause. It is evident now that Hsp90β is the root of dose-limiting toxicity (DLT), whereas Hsp90α is a buffer of penetrated Hsp90 inhibitors. The more Hsp90α, the safer Hsp90β, and the lower DLT are for the host. Unfortunately, the dramatic variations of Hsp90, from total absence in the eye, muscle, pancreas, and heart to abundance in reproduction organs, lung, liver, and gastrointestinal track, would cause the selection of any fair toxicity biomarker and an effective maximum tolerable dose (MTD) of Hsp90 inhibitor extremely challenging. In theory, a safe MTD for the organs with high Hsp90 could harm the organs with low Hsp90. In reverse, a safe MTD for organs with low or undetectable Hsp90 would have little impact on the tumors, whose cells exhibit average 3–7% Hsp90 over the average 2–3% Hsp90 in normal cells. Moreover, not all tumor cell lines tested follow the “inhibitor binding-client protein degradation” paradigm. It is likely why the oral Hsp90 inhibitor TAS-16 (Pimitespib), which bypasses blood circulation and other organs, showed some beneficiary efficacy by conveniently hitting tumors along the gastrointestinal track. The critical question is what the next step will be for the Hsp90 chaperone as a cancer therapeutic target.</p></div>","PeriodicalId":9684,"journal":{"name":"Cell Stress & Chaperones","volume":"29 5","pages":"Pages 642-653"},"PeriodicalIF":3.3,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1355814524001135/pdfft?md5=bb6803984815a0bac43a72463f215aff&pid=1-s2.0-S1355814524001135-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142055099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The knowledge generated in this framework can be actionable for the design and development of chemical tools and drugs targeting Hsp90 in specific disease-associated cellular contexts.
