CRISPR based therapeutic targeting of signaling pathways in breast cancer
Biochim Biophys Acta Mol Basis Dis. 2023 Sep 2:166872. doi: 10.1016/j.bbadis.2023.166872. Online ahead of print.ABSTRACTBreast cancer represents the prevailing malignancy in females and contributing towards mortality on a global scale. There are innumerable anomalous genes that are responsible in the multi factorial carcinogenesis pathway. Although several disease-causing mutations have been detected, therapy frequently focuses on attenuating the manifestation of the disease rather than harmonizing the mutation in the target area. However, the emergence of the CRISPR-Cas system as a DNA modifying tool has proved to be a pr...

Flexibility in the bridge of chalcone derivatives is important for the inhibition of cellular growth
Bioorg Med Chem Lett. 2023 Sep 2:129467. doi: 10.1016/j.bmcl.2023.129467. Online ahead of print.ABSTRACTChalcones and their derivatives are a privileged scaffold in medicinal chemistry, demonstrating numerous biological activities. These molecules have shown significant potential toward the development of novel cancer therapies. While much is known about modification to the chalcone aryl rings, little is known about conformations of the bridge between the aryl rings. Here we report the synthesis and biological evaluation of a series of molecules with flexible and rigid bridge conformations. Crystal structures of a select g...

Online ahead of print.ABSTRACTRecent technological advancements in testing and monitoring instrumentation have greatly contributed to the progress in cancer treatment by surgical, chemotherapeutic and radiotherapeutic interventions. However, the mortality rate still remains high, calling for the development of new treatment strategies with higher efficacy. Extensive efforts driven in this direction have included broadening of early cancer screening and applying innovative theranostic nanotechnologies. They have been supported by platforms introdu...

Design, synthesis and biological evaluation of pyrimidine base hydroxamic acid derivatives as dual JMJD3 and HDAC inhibitors
In this study, based on rational drug design strategy, we designed and synthesized a series of pyrimidine derivatives with hydroxamic acid as novel dual JMJD3 and HDAC inhibitors for synergistic cancer treatment. Compound A5b exhibited inhibitory potency against JMJD3 and HDAC1/6 simultaneously and favorable cytotoxicity against human cancer cells such as A549 and U937. Furthermore, mechanistic studies showed that A5b treatment in A549 cells increased the hypermethylation of histone H3K27 and hyperacetylation of H3K9, suppressed clonogenicity, migration and invasion of cancer cells. Besides, A5b induced apoptosis via the c...

A practical approach to the ESC 2022 cardio-oncology guidelines. Comments by a team of experts: cardiologists and oncologists
Kardiol Pol. 2023 Sep 3. doi: 10.33963/v.kp.96840. Online ahead of print.ABSTRACTThe 2022 European Society of Cardiology (ESC) guidelines [1] are a comprehensive document, prepared jointly by experts in cardiology and oncology. In the case of an oncological patient, it is necessary to individualize care in relation to the cardiological condition, the stage of the cancer and the type of potential anti-cancer therapy. Cardiac care optimisation should be undertaken before the start of oncological therapy, and continued during oncological therapy, as well as long-term after its completion [2]. The published ESC Guidelines were...

Subverted macrophages in the triple-negative breast cancer ecosystem
Biomed Pharmacother. 2023 Sep 1;166:115414. doi: 10.1016/j.biopha.2023.115414. Online ahead of print.ABSTRACTTumor-associated macrophages (TAMs) are the most critical effector cells of innate immunity and the most abundant tumor-infiltrating immune cells. They play a key role in the clearance of apoptotic bodies, regulation of inflammation, and tissue repair to maintain homeostasis in vivo. With the progression of triple-negative breast cancer（TNBC）, TAMs are "subverted" from tumor-promoting immune cells to tumor-promoting immune suppressor cells, which play a significant role in tumor development and are considered po...

Collagen code in tumor microenvironment: Functions, molecular mechanisms, and therapeutic implications
Biomed Pharmacother. 2023 Sep 1;166:115390. doi: 10.1016/j.biopha.2023.115390. Online ahead of print.ABSTRACTThe tumor microenvironment (TME) is crucial in cancer progression, and the extracellular matrix (ECM) is an important TME component. Collagen is a major ECM component that contributes to tumor cell infiltration, expansion, and distant metastasis during cancer progression. Recent studies reported that collagen is deposited in the TME to form a collagen wall along which tumor cells can infiltrate and prevent drugs from working on the tumor cells. Collagen-tumor cell interaction is complex and requires the activation o...

Role of cancer-educated mesenchymal stromal cells on tumor progression
Biomed Pharmacother. 2023 Sep 1;166:115405. doi: 10.1016/j.biopha.2023.115405. Online ahead of print.ABSTRACTThe malignant tumor is the main cause of human deaths worldwide. Current therapies focusing on the tumor itself have achieved unprecedented benefits. Various pro-tumorigenic factors in the tumor microenvironment (TME) could abolish the effect of cancer therapy. Mesenchymal stromal cells (MSCs) are one of the substantial components in the tumor microenvironment, contributing to tumor progression. However, MSCs are not inherently tumor-promoting. Indeed, they acquire pro-tumorigenic properties under the education of t...
