[PMID: 38818695 DOI: 10.1080/07357907.2024.2359987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Accepted: 05/22/2024] [Indexed: 06/01/2024]
Abstract
Addressing recurrent cervical cancer poses a substantial challenge. Osimertinib, an FDA-approved EGFR inhibitor, has emerged as a promising option. Our study examined its potential to enhance paclitaxel's efficacy against cervical cancer. Osimertinib effectively hindered cancer cell growth and induced apoptosis across multiple cell lines. Combined with paclitaxel, it exhibited synergy in suppressing cervical cancer cells. Importantly, osimertinib's inhibitory effect was EGFR-independent; it targeted Mnk phosphorylation, reducing eIF4E activity. In mice, the combined osimertinib-paclitaxel treatment surpassed individual drugs in inhibiting cancer growth. These preclinical findings suggest osimertinib's repurposing as a means to improve paclitaxel's effectiveness in cervical cancer treatment.

Abstract
Gynecologic malignancies (GMs) are relatively less focused cancers by oncologists and researchers. The five-year survival rate of patients with GMs remained almost the same during the last decade. The development of drug resistance GMs makes it even more challenging to tackle due to tumor heterogeneity, genomic instability, viral/non-viral antigens, and etiological tumor origin. A precision medicine approach, including gene therapies, is under testing to restore tumor responsiveness to therapeutics and immunotherapy. With more data being uncovered, immunotherapy is emerging as a viable alternative for achieving promising results. This review highlights the drug resistance mechanisms and immunotherapeutic approaches to managing GMs better. The approval of immune therapeutic drugs in recent years shifted this notion. It provided hope for researchers, clinicians, and patients with GMs to experience the anti-cancer benefits of these therapies.

Abstract
Kaposiform lymphangiomatosis (KLA) is a life-threatening rare disease that can cause substantial morbidity, mortality, and social burdens for patients and their families. Diagnosis often occurs long after initial symptoms, and there are few centers in the world with the expertise to diagnose and care for patients with the disease. KLA is a lymphatic anomaly and significant advancements have been made in understanding its pathogenesis and etiology since its first description in 2014. This review provides multidisciplinary, comprehensive, and state-of-the-art information on KLA patient presentation, diagnostic imaging, pathology, organ involvement, genetics, and pathogenesis. Finally, we describe current therapeutic approaches, important areas for research, and challenges faced by patients and their families. Further insights into the pathogenesis of KLA may advance our understanding of other vascular anomalies given that similar signaling pathways may be involved.

Abstract
Despite a high efficacy of chemotherapy in cancer treatment, acquired resistance of tumors to certain chemotherapeutic agents and frequent side effects remain the major factors of unfavorable prognosis in most cancer patients with unresectable, metastatic and recurrent forms of the disease. The discovery of novel molecular targets in tumors and development of new therapeutic approaches to enhance the efficiency of chemotherapeutic agents remain the biggest challenges in current oncology. Here we examined the ability of pyrrole-based heterocyclic compound 2-APC to sensitize tumor cells to the topoisomerase II inhibitor doxorubicin. The study was performed on human cancer cell lines treated with 2-APC, paclitaxel, and doxorubicin. Expression of DNA repair was investigated by Western blotting, whereas protein-protein interactions were examined by co-immunoprecipitation. The synergism between the chemotherapeutic agents was assessed with the Synergy Finder program. Doxorubicin exhibited moderate cytotoxic effect against cancer cell lines (in particular, osteosarcoma cell lines). 2-APC in non-toxic concentrations substantially potentiated the cytotoxic effect of doxorubicin and induced apoptosis of cancer cells. This activity of 2-APC was due to its ability to impair DNA damage repair by decreasing the content of Rad51 recombinase via promoting its proteasomal degradation. Similar effects were observed for paclitaxel, which affects tubulin polymerization. Therefore, chemotherapeutic agents and chemical compounds interfering with the microtubule dynamics can potentiate the cytotoxic effects of DNA-damaging chemotherapeutic agents via impairment of DNA damage repair mechanisms in cancer cells.

Abstract
Worldwide, cervical cancer was the fourth leading cause of cancer death among women, while in Mexico was the second cause (5.28%). Cancer patients receiving chemotherapy and radiotherapy have a high risk of malnutrition secondary to the disease and treatment, affects the patient's overall, with adverse effects on gastrointestinal symptoms. These use affects the medical therapy. The aim of the present study was to evaluate the benefits on individualized nutritional therapy on decrease weight loss and gastrointestinal adverse effects and to consider these outcomes in pharmacology research, especially in repurposing drugs. We conducted a longitudinal design with two comparation groups with medical diagnosis of cervical cancer and received radiotherapy weekly, 1) the intervention group (nutritional intervention and counseling -INC-) with 20 participants and 2) control group (retrospective cohort -CG-) with 9 participants. Weekly body composition, dietary intake, adverse effects (gastrointestinal symptoms), glucose, hemoglobin, and blood pressure were analyzed during 4 to 5 weeks. Both groups had weight loss weekly (p = 0.013 and p = 0.043 respectively) but the CG vs INC presented loss fat-free mass ≥500g in 67 and of 37% respectively. By the end of the intervention a 25% of the INC group had <10 g/dL of hemoglobin vs 60% for the CG. To compare the dietary intake of vitamins (A and folic acid), fiber (p = 0.006), iron (p = 0.03) and energy (mainly carbohydrates) (p = 0.04) were according to the recommendations in INC group (p>0.05). The number needed to treat was 4 (95% CI, 2 to 13). The nutritional intervention and counseling weekly during radiotherapy in cervical cancer to maintain/improve muscle mass, hemoglobin, and dietary intake above 70% of the recommendations for INC group compared to the evidence. Adequate nutritional status was maintained and decrease the rate of complications, mainly gastrointestinal symptoms, in INC group. The efficacy of drug repurposing can improve through individualized nutritional therapy for preventing adverse effects of radiotherapy in patients with cervical cancer.

Abstract
RAS was identified as a human oncogene in the early 1980s and subsequently found to be mutated in nearly 30% of all human cancers. More importantly, RAS plays a central role in driving tumor development and maintenance. Despite decades of effort, there remain no FDA approved drugs that directly inhibit RAS. The prevalence of RAS mutations in cancer and the lack of effective anti-RAS therapies stem from RAS' core role in growth factor signaling, unique structural features, and biochemistry. However, recent advances have brought promising new drugs to clinical trials and shone a ray of hope in the field. Here, we will exposit the details of RAS biology that illustrate its key role in cell signaling and shed light on the difficulties in therapeutically targeting RAS. Furthermore, past and current efforts to develop RAS inhibitors will be discussed in depth.

Zoledronic acid inhibits the growth of leukemic MLL-AF9 transformed hematopoietic cells. Heliyon 2020; 6:e04020.

Abstract
A leukemic in vitro model produced by transducing Cord Blood derived-hematopoietic CD34+ cells with the MLL-AF9 translocation resulting in the oncogenic fusion protein, is used to assess for sensitivity to Zoledronic acid. These cells are practically immortalized and are of myeloid origin. Proliferation, clonogenic and stromal co-culture assays showed that the MLL-AF9 cells were considerably more sensitive to Zoledronic acid than normal hematopoietic CD34+ cells or MS-5 stromal cells. The MLL-AF9 cells were notably more inhibited by Zoledronic acid when cultured as colonies in 3 dimensions, requiring cell-cell contacts compared to suspension expansion cultures. This is coherent with the mechanism of action of Zoledronic acid inhibiting farnesyl diphosphate synthase which results in a block in prenylation of GTPases such that their role in the membrane is compromised for cell-cell contacts. Zoledronic acid can be proposed to target the MLL-AF9 leukemic stem cells before they emerge from the hematopoietic niche, which being in proximity to bone osteoclasts where Zoledronic acid is sequestered can be predicted to result in sufficient levels to result in an anti-leukemic action.
