[PMID: 38470012 DOI: 10.1002/tox.24204] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Revised: 02/05/2024] [Accepted: 02/18/2024] [Indexed: 03/13/2024]
Abstract
Recurrence of breast cancer may be due to the presence of breast cancer stem cells (BCSC). Abnormal tumor cell growth is closely associated with increased reactive oxygen species (ROS) and disruption of redox homeostasis, and BCSCs exhibit low levels of ROS. The detailed mechanism between the low levels of ROS in BCSCs and their maintenance of stemness characteristics has not been reported. A growing number of studies have shown that tumor development is often accompanied by metabolic reprogramming, which is an important hallmark of tumor cells. As the first rate-limiting enzyme of pentose phosphate pathway (PPP), the expression of G6PD is precisely regulated in tumor cells, and there is a certain correlation between PPP and BCSCs. MiR-375 has been shown to inhibit stem cell-like properties in breast cancer, but the exact mechanism is not clear. Here, KLF5, as a transcription factor, was identified to bind to the promoter of G6PD to promote its expression, whereas miR-375 inhibited the expression of KLF5 by binding to the 3'UTR region of KLF5 mRNA and thus reduced the expression of G6PD expression, inhibits PPP to reduce NADPH, and increases ROS levels in breast cancer cells, thereby weakening breast cancer cell stemness. Our study reveals the specific mechanism by which miR-375 targets the KLF5/G6PD signaling axis to diminish the stemness of breast cancer cells, providing a therapeutic strategy against BCSCs.

Abstract
Benzopyran nitrile dyes cannot be used as qualified photosensitizers due to the low quantum yield of triplet state. The benzopyran derivatives containing selenium instead of oxygen atom based on the heavy atom effect are expected to become potential agents for photodynamic therapy. In this paper, a series of selenium-containing photosensitizers (PSX) were prepared according to this strategy. PSX can effectively produce both singlet oxygen and superoxide anions upon laser irradiation. PSX exhibited the emission wavelength at 500-800 nm and near-infrared (NIR) fluorescence imaging in HeLa cells. Excellent biocompatibility and phototoxicity further indicated that PSX could be used as efficient photosensitizers for NIR fluorescence imaging and photodynamic therapy.

Abstract
In the past decade, bacteria-based cancer immunotherapy has attracted much attention in the academic circle due to its unique mechanism and abundant applications in triggering the host anti-tumor immunity. One advantage of bacteria lies in their capability in targeting tumors and preferentially colonizing the core area of the tumor. Because bacteria are abundant in pathogen-associated molecular patterns that can effectively activate the immune cells even in the tumor immunosuppressive microenvironment, they are capable of enhancing the specific immune recognition and elimination of tumor cells. More attractively, during the rapid development of synthetic biology, using gene technology to enable bacteria to be an efficient producer of immunotherapeutic agents has led to many creative immunotherapy paradigms. The combination of bacteria and nanomaterials also displays infinite imagination in the multifunctional endowment for cancer immunotherapy. The current progress report summarizes the recent advances in bacteria-based cancer immunotherapy with specific foci on the applications of naive bacteria-, engineered bacteria-, and bacterial components-based cancer immunotherapy, and at the same time discusses future directions in this field of research based on the present developments.

J Cell Biochem 2019; 120:7778-7787.

Abstract
Intracellular reactive oxygen species (ROS) play important roles in the ex vivo expansion of hematopoietic stem and progenitor cells (HSPCs). In this study, the effects of resveratrol (RES), on the ex vivo expansion of HSPCs were investigated by analyzing CD34+ cells expansion and biological functions, with the objective to optimize ex vivo culture conditions for CD34 + cells. Among the five tested doses (0, 0.1, 1, 10, 20, and 50 μM), 10 μM RES was demonstrated to be the most favorable for ex vivo CD34 + cells expansion. In the primary cultures, 10 μM RES favored higher expansion folds of CD34 + cells, CD34 + CD38 - cells, and colony-forming units (CFUs) ( P < 0.05). It was found that the percentages of primitive HSPCs (CD34 + CD38 - CD45R - CD49f + CD90 + cells) in 10 μM RES cultures were higher than those without RES. Further, in the secondary cultures, expanded CD34 + cells derived from primary cultures with 10 μM RES exhibited significantly higher total cells and CD34 + cells expansion ( P < 0.05). In the semisolid cultures, the frequency of CFU-GM and total CFUs of 10 μM RES group were both higher than those of without RES group, demonstrating that CD34 + cells expanded with 10 μM RES possessed better biological function. Furthermore, the addition of 10 μM RES downregulated the intracellular ROS level via strengthening the scavenging capability of ROS, and meanwhile reducing the percentages of apoptotic cells in cultures. Collectively, RES could stimulate the ex vivo expansion of CD34 + cells, preserved more primitive HSPCs and maintain better biological function by alleviating intracellular ROS level and cell apoptosis in cultures.

Hyperbaric oxygen treatment produces an antinociceptive response phase and inhibits astrocyte activation and inflammatory response in a rat model of neuropathic pain. J Mol Neurosci 2014; 53:251-61. [PMID: 24390961 DOI: 10.1007/s12031-013-0213-3] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2013] [Accepted: 12/15/2013] [Indexed: 10/25/2022]
Abstract
Hyperbaric oxygen (HBO) treatment has been proven to be a promising candidate for protection of the nervous system after acute injury in animal models of neuropathic pain. The purposes of this study were to examine the antinociceptive response phase induced by HBO treatment in a model of neuropathic pain and to determine the dependence of the treatment's mechanism of alleviating neuropathic pain on the inhibition of spinal astrocyte activation. Neuropathic pain was induced in rats by chronic constriction injury of the sciatic nerve. Mechanical threshold and thermal latency were tested preoperatively and for 1 week postoperatively, four times daily at fixed time points. Methane dicarboxylic aldehyde (MDA) and superoxide dismutase (SOD) parameters were used as indices of oxidative stress response and tested before and after the treatment. The inflammatory cytokines interleukin (IL)-1β and IL-10 were assayed in the sciatic nerve were with enzyme-linked immunoassay. Glial fibrillary acidic protein activation in the spinal cord was evaluated immunohistochemically. The rats exhibited temporary allodynia immediately after HBO treatment completion. This transient allodynia was closely associated with changes in MDA and SOD levels. A single HBO treatment caused a short-acting antinociceptive response phase. Repetitive HBO treatment led to a long-acting antinociceptive response phase and inhibited astrocyte activation. These results indicated that HBO treatment played a dual role in the aggravation and alleviation of neuropathic pain, though the aggravated pain effect (transient allodynia) was far less pronounced than the antinociceptive phase. Astrocyte inhibition and anti-inflammation may contribute to the antinociceptive effect of HBO treatment after nerve injury.

Comparison of two-stage epidermal carcinogenesis initiated by 7,12-dimethylbenz(a)anthracene or N-methyl-N'-nitro-N-nitrosoguanidine in newborn and adult SENCAR and BALB/c mice. Cancer Res 1981; 17:md17090526. [PMID: 31505769 PMCID: PMC6780187 DOI: 10.3390/md17090526] [Citation(s) in RCA: 14] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2019] [Revised: 09/06/2019] [Accepted: 09/06/2019] [Indexed: 12/19/2022]
Abstract
In order to define factors which determine susceptibility to chemical carcinogenesis, mice sensitive (SENCAR) and resistant (BALB/c) to epidermal carcinogenesis were studied under several treatment conditions for sensitivity to initiation by 7,12-dimethylbenz(a)anthracene or N-methyl-N'-nitro-N-nitrosoguanidine and promotion by 12-O-tetradecanoylphorbol-13-acetate. In newborns of both strains, topical application of initiator was much less effective than in adults. However, initiation by i.p. injection of 7,12-dimethylbenz(a)anthracene is at least as effective in newborns as in adults, which may indicate that topically applied carcinogen is not delivered effectively to target cells in newborns. Thus, newborn epidermis can respond to 7,12-dimethylbenz(a)anthracene as well as adult epidermis when the initiator is appropriately administered. SENCAR mice are much more sensitive than are BALB/c mice to both initiators, which suggests that enhanced metabolic activation of hydrocarbon carcinogens by SENCAR mice is unlikely to account for their sensitivity. Newborn male SENCAR's developed approximately 50% more papillomas than did females in all groups. BALB/c newborn mice developed so few tumors that a meaningful comparison of sensitivity of males and females could not be made. Thus, the increased sensitivity of SENCAR's was apparent regardless of route of administration of initiator or the age or sex of the mice. SENCAR mice also developed a significant number of papillomas and squamous cell carcinomas with 12-O-tetradecanoylphorbol-13-acetate promotion in the absence of an exogenous initiator. Therefore, the skin of SENCAR mice may contain an initiated population of cells capable of responding to tumor promoters.
