Abstract
The presence of HSPs in female reproductive and their relationship with the steroid hormone fluctuation have been reported in several mammals but not in non-human primates. The present research dealt with the oviductal expression and localization of the more studied HSPs (60, 70, and 90) as well as the morphological changes in the Hamadryas baboon (Papio hamadryas) during the follicular, preovulatory, and luteal phases of the menstrual cycle. Therefore, western blots, histomorphological, and immunohistochemical analyses were carried out. The results of western blot analysis displayed the lowest HSP expression in the luteal phase. The histomorphology showed that the mucosal epithelium consisted of undifferentiated cuboidal cells in follicular and luteal phases and well-distinguishable columnar ciliated and non-ciliated cells during the preovulatory phase. Immunohistochemistry evidenced that the mucosal epithelium contained cytoplasmic and nuclear HSP60, 70, and 90 immunostaining in the follicular and luteal phases. During the preovulatory phase, the non-ciliated cells showed: (i) cytoplasmic HSP60; (ii) nuclear and cytoplasmic HSP90. Ciliated cells showed cytoplasmic and ciliary HSP70 and ciliary HSP90. The stromal cells and myocytes of muscular layer displayed a decreased cytoplasmic HSP60 in the preovulatory phase and nuclear and low cytoplasmic HSP70 throughout the menstrual cycle. Nuclear HSP90 decreased in ampulla stromal cells and the follicular phase myocytes. These findings indicate that the expression pattern of HSP60,70, and 90 is related to the morphofunctional features of the baboon oviductal ampulla during the menstrual cycle and could represent a referent point for further studies in the oviduct of Primates.

Acta Biochim Biophys Sin (Shanghai) 2015; 47:451-8.

Abstract
Heat shock protein 90 (Hsp90) is a fascinating target for cancer therapy due to its significant role in the crossroad of multiple signaling pathways associated with cell proliferation and regulation. Hsp90 inhibitors have the potential to be developed into anti-cancer drugs. Here, we identified nicotinic-mycoepoxydiene (NMD), a structurally novel compound as Hsp90 inhibitor to perform the anti-tumor activity. The compound selectively bound to the Hsp90 N-terminal domain, and degraded the Hsp90 client protein Akt. The degradation of Akt detained Bad in non-phosphorylation form. NMD-associated apoptosis was characterized by the formation of fragmented nuclei, poly(ADP-ribose) polymerase cleavage, cytochrome c release, caspase-3 activation, and the increased proportion of sub-G1 phase cells. Interestingly, the apoptosis was accompanied with autophagy, by exhibiting the increased expression of LC-3 and the decrease of lysosome pH value. Our findings provide a novel cellular mechanism by which Hsp90 inhibitor adjusts cell apoptosis and autophagy in vitro, suggesting that NMD not only has a potential to be developed into a novel anti-tumor pharmaceutical, but also exhibits a new mechanism in regulating cancer cell apoptosis and autophagy via Hsp90 inhibition.

Abstract
Programmed cell death (PCD) has important implications in the biology of unicellular parasites, especially in devising control strategies against them. In this study, we examined the role of metacaspase LdMC1 and heat shock protein Hsp70 in Leishmania donovani through transient gene knockdown using antisense oligonucleotides (ASOs), during MG132-induced PCD. Proteasome inhibitor MG132 was used for inducing PCD in the in vitro culture of Leishmania donovani, which was confirmed by morphological and molecular markers. To assess the role of LdMC1 and Hsp70, ASOs with partially modified phosphorothioate backbone were designed against the protein-coding regions of these genes. Promastigotes and axenic ALFs were exposed to ASOs, and gene knockdown was confirmed using RT-PCR. Exposure to MG132 and ASOs led to morphological defects, DNA fragmentation, delay in progressing through the S-phase of cell-cycle and a decrease in the mitochondrial membrane potential. Antisense knockdown of both these genes, individually as well as together, caused phenotypic and molecular characteristics of PCD. Simultaneous knockdown of both LdMC1 and Hsp70 led to a severity in these defects. Parasites co-exposed to MG132 along with ASOs suffered the maximum damage. Together, these data suggest that LdMC1 and Hsp70 have an indispensable role in Leishmania cell-cycle and are, therefore, important for its survival.

Abstract
Heat shock proteins (HSP) are a family of proteins induced in cells exposed to different insults. This induction of HSPs allows cells to survive stress conditions. Mammalian HSPs have been classified into six families according to their molecular size: HSP100, HSP90, HSP70, HSP60, HSP40 and small HSPs (15 to 30kDa) including HSP27. These proteins act as molecular chaperones either helping in the refolding of misfolded proteins or assisting in their elimination if they become irreversibly damaged. In recent years, proteomic studies have characterized several different HSPs in various tumor types which may be putative clinical biomarkers or molecular targets for cancer therapy. This has led to the development of a series of molecules capable of inhibiting HSPs. Numerous studies speculated that over-expression of HSP is in part responsible for resistance to many anti-tumor agents and chemotherapeutics. Hence, from a pharmacological point of view, the co-administration of HSP inhibitors together with other anti-tumor agents is of major importance in overcoming therapeutic resistance. In this review, we provide an overview of the current status of HSPs in autoimmune, cardiovascular, and neurodegenerative diseases with special emphasis on cancer.

Abstract
BACKGROUND Endoplasmic reticulum stress (ERS), the unfolded protein response (UPR) and apoptosis signal transduction pathways are fundamental to normal cellular homeostasis and survival, but are exploited by cancer cells to promote the cancer phenotype. OBJECTIVE Collateral activation of ERS and UPR role players impact on cell growth, cell cycle arrest or apoptosis, genomic stability, tumour initiation and progression, tumour aggressiveness and drug resistance. An understanding of these processes affords promising prospects for specific cancer drug targeting of the ERS, UPR and apoptotic pathways. METHOD This review (Part II of II) brings forward the latest developments relevant to the molecular connections among cell cycle regulators, caspases, NF-κB, and the proteasome with ERS and UPR signalling cascades, their functions in apoptosis induction, apoptosis resistance and oncogenesis, and how these relationships can be exploited for targeted cancer therapy. CONCLUSION Overall, ERS, the UPR and apoptosis signalling cascades (the molecular therapeutic targets) and the development of drugs that attack these targets signify a success story in cancer drug discovery, but a more reductionist approach is necessary to determine the precise molecular switches that turn on antiapoptotic and pro-apoptotic programmes.

Abstract
BACKGROUND In eukaryotes, endoplasmic reticulum stress (ERS) and the unfolded protein response (UPR) are coordinately regulated to maintain steady-state levels and activities of various cellular proteins to ensure cell survival. OBJECTIVE This review (Part I of II) focuses on specific ERS and UPR signalling regulators, their expression in the cancer phenotype and apoptosis, and proposes how their implication in these processes can be rationalised into proteasome inhibition, apoptosis induction and the development of more efficacious targeted molecular cancer therapies. METHOD In this review, we contextualise many ERS and UPR client proteins that are deregulated or mutated in cancers and show links between ERS and the UPR, their implication in oncogenic transformation, tumour progression and escape from immune surveillance, apoptosis inhibition, angiogenesis, metastasis, acquired drug resistance and poor cancer prognosis. CONCLUSION Evasion of programmed cell death or apoptosis is a hallmark of cancer that enables tumour cells to proliferate uncontrollably. Successful eradication of cancer cells through targeting ERS- and UPR-associated proteins to induce apoptosis is currently being pursued as a central tenet of anticancer drug discovery.
