Mitochondria have a complete and independent genetic system with necessary biological energy for cancer occurrence and persistence. Mitochondrial RNA (mt-RNA) methylation, as a frontier in epigenetics, has linked to cancer progression with growing evidences. This review has comprehensively summarized detailed mechanisms of mt-RNA methylation in regulating cancer proliferation, metastasis, and immune infiltration from the mt-RNA methylation sites, biological significance, and its methyltransferases. The mt-RNA methylation also plays a very significant role via epigenetic crosstalk between nucleus and mitochondria. Importantly, the unique structures and functional characteristics of mt-RNA methyltransferases and the potential targeting treatment drugs for cancer are also analyzed. Revealing human mt-RNA methylation regulatory system and the relationship with cancer will contribute to identifying potential biomarkers and therapeutic targets for precise prevention, detection, intervention and treatment in the future.

RNF43 and ZNRF3 are recognized as important regulators of Wnt/β-catenin signaling by maintaining Wnt-receptors at minimal essential levels. In various cancer types, particularly gastrointestinal tumors, mutations in these genes lead to abnormal Wnt-dependent activation of β-catenin signaling. However, recent findings implicate RNF43/ZNRF3 also in the regulation of other tumor-related proteins, including EGFR, BRAF, and the BMP-signaling pathway, which may have important implications for tumor biology. Additionally, we describe in detail how phosphorylation and ubiquitination may finetune RNF43 and ZNRF3 activity. We also address the variety of mutations observed in cancers and the mechanism through which they support tumor growth, and challenge the prevailing view that specific missense mutations in the R-spondin and RING domains may possess dominant-negative activity in contributing to tumor formation.

The bottleneck on therapeutics and diagnostics is removed by an alternate approach known as theranostics which combines both therapeutics and diagnostics within a single platform. Due to this “all in one” nature of theranostics, it is now extensively applied in the medicinal field mainly in cancer treatment over the conventional therapy. Recently, FDA approval of lutetium 177 (177Lu) DOTATATE and 177Lu–PSMA-based radionuclide theranostics are clinically used and very few theranostics specific to breast cancer are in clinical trials. In this review, we are willing to draw special attention to the application of theranostics in the most relevant cancers in women, the breast and the cervical as these cancers affect women harshly but talked very silently due to the social restrictions and discriminations mainly in rural areas of developing and under developing countries. This approach not only combines therapeutics and diagnostics but targeting moieties can also be accommodated for the precise medication. Herein, our main objective is to enlighten the broader aspects of different kinds of theranostic devices based on radioisotopes, nanoparticles, graphene quantum dots, dendrimers and their fruitful application against breast and cervical cancer. The development of synthetic nano-theranostics was reported by accommodating therapeutic drugs, imaging probes and targeting ligands through conjugation or encapsulation. The imaging modalities like optical fluorescence, photosensitizers and radiotracers are used to get the diagnostic images through NIR, PET, MRI and CT/SPECT to detect the progress of cancer non-invasively and also at the same time targeting ligands such as antibodies, proteins and peptides in attachment with the theranostics enhances the therapeutic efficacy in addition to the clarity in diagnostics. The applications of theranostics from the last decade with their present scenario in clinics and future perspectives, as well as the pitfalls with the hurdles that still leave questions to rethink from the root are also been discussed in this review.

Neutrophils, the most abundant leukocyte population in circulation, play a crucial role in detecting and responding to foreign cells, such as pathogens and tumor cells. However, the impact of neutrophils on cancer pathogenesis has been overlooked because of their short lifespan, terminal differentiation, and limited transcriptional activity. Within the tumor microenvironment (TME), neutrophils can be influenced by tumor cells or other stromal cells to acquire either protumor or antitumor properties via the cytokine environment. Despite progress in neutrophil-related research, a comprehensive understanding of tissue-specific neutrophil diversity and adaptability in the TME is still lacking, which poses a significant obstacle to the development of neutrophil-based cancer therapies. This review evaluated the current studies on the dual roles of neutrophils in cancer progression, emphasizing their importance in predicting clinical outcomes, and explored various approaches for targeting neutrophils in cancer treatment, including their potential synergy with cancer immunotherapy.

Drug resistance is a significant challenge in oncology and is driven by various mechanisms, among which a crucial role is played by enhanced DNA repair. Thus, targeting DNA damage response (DDR) factors with specific inhibitors is emerging as a promising therapeutic strategy. An important process involved in the modulation of DNA repair pathways, and hence in drug resistance, is post-translational modification (PTM). PTMs such as methylation affect protein function and are critical in cancer biology. Methylation is catalyzed by specific enzymes called protein methyltransferases. In recent years, the SET domain-containing N-lysine methyltransferase SMYD3 has emerged as a significant oncogenic driver. It is overexpressed in several tumor types and plays a signal-dependent role in promoting gastrointestinal cancer formation and development. Recent evidence indicates that SMYD3 is involved in the maintenance of cancer genome integrity and contributes to drug resistance in response to genotoxic stress by regulating DDR mechanisms. Several potential SMYD3 interactors implicated in DNA repair, especially in the homologous recombination and non-homologous end-joining pathways, have been identified by in silico analyses and confirmed by experimental validation, showing that SMYD3 promotes DDR protein interactions and enzymatic activity, thereby sustaining cancer cell survival. Targeting SMYD3, in combination with standard or targeted therapy, shows promise in overcoming drug resistance in colorectal, gastric, pancreatic, breast, endometrial, and lung cancer models, supporting the integration of SMYD3 inhibition into cancer treatment regimens. In this review, we describe the role played by SMYD3 in drug resistance and analyze its potential as a molecular target to sensitize cancer cells to treatment.
耐药性是肿瘤学面临的一项重大挑战，其驱动机制多种多样，其中 DNA 修复能力的增强发挥了至关重要的作用。因此，以 DNA 损伤应答（DDR）因子为靶点的特异性抑制剂正成为一种前景广阔的治疗策略。DNA 修复途径的一个重要调节过程是翻译后修饰 (PTM)，这也是导致耐药性的一个重要原因。甲基化等 PTM 会影响蛋白质的功能，在癌症生物学中至关重要。甲基化由称为蛋白质甲基转移酶的特定酶催化。近年来，含 SET 结构域的 N-赖氨酸甲基转移酶 SMYD3 已成为一种重要的致癌驱动因子。它在几种肿瘤类型中过度表达，并在促进胃肠癌的形成和发展中发挥着信号依赖性作用。最近的证据表明，SMYD3 参与了癌症基因组完整性的维护，并通过调节 DDR 机制在应对基因毒性压力时产生抗药性。一些潜在的 SMYD3 与 DNA 修复（尤其是同源重组和非同源末端连接途径）有关的相互作用因子已通过硅学分析确定，并通过实验验证得到证实，表明 SMYD3 促进了 DDR 蛋白相互作用和酶活性，从而维持了癌细胞的存活。在结直肠癌、胃癌、胰腺癌、乳腺癌、子宫内膜癌和肺癌模型中，靶向 SMYD3 与标准疗法或靶向疗法相结合，有望克服耐药性，支持将 SMYD3 抑制纳入癌症治疗方案。在这篇综述中，我们描述了 SMYD3 在耐药性中扮演的角色，并分析了其作为分子靶点使癌细胞对治疗敏感的潜力。

The urological system, including kidneys, ureters, bladder, urethra and prostate is known to be vital for blood filtration, waste elimination and electrolyte balance. Notably, urological system cancers represent a significant portion of global cancer diagnoses and mortalities. The current therapeutic strategies for early-stage cancer primarily involve resection surgery, which significantly affects the quality of life of patients, whereas advanced-stage cancer often relies on less effective chemo- or radiotherapy. Recently, accumulating evidence has revealed that autophagy, a crucial process in which excess organelles or inclusions within cells are removed to maintain cell homeostasis, has numerous links to urological system cancers. In this review, we focus on summarizing the underlying two-sided mechanisms of autophagy in urological system cancers. We also review the current clinical drugs targeting autophagy, which demonstrate significant potential in improving treatment outcomes for urological system cancers. In addition, we provide an overview of the research status of novel small molecule compounds targeting autophagy that are in the preclinical stages of investigation. Furthermore, drug combinations based on autophagy modulation strategies in urological system cancers are systematically summarized and discussed. These findings provide comprehensive new insight for the future discovery of more autophagy-related drug candidates.

Tumour metastasis is a crucial factor in determining clinically challenging tumours. In this respect, the lymphatic system may act as potential entry portals for tumour metastasis, whilst, clinical detection of tumour-infiltrated lymph nodes also indicates poorer prognosis and higher metastatic risk. Whether tumour cells gain ferroptosis resistance in lymph that make them exhibit a stronger propensity for lymphatic dissemination compared to hematogenous spread might be a breakthrough for elucidating lymph-associated tumour metastasis. This review discusses how the lymphatic system endows tumour cells with ferroptosis resistance character, which makes them more propensity for lymph node pre-metastasis and distant metastasis through lymphatic circulation. Comprehensively considering the distinct structure and property of lymph and the unique metabolic characteristics of tumours, all of the lymphatic vessels, intestinal lymph and lymph nodes collectively manipulate an intricate interaction with the hematogenous system and afford substances exchange with tumour cells and extracellular vesicles, upon which make a ferroptosis resistant microenvironment for subsequent metastasis in distant organs and lymph nodes.

Human endogenous retroviruses (HERVs) are a class of transposable elements formed by the integration of ancient retroviruses into the germline genome. They are inherited in a Mendelian manner and approximately constitute 8 % of the human genome. HERVs were considered as “junk DNA” for decades, but increasing evidence suggests that they play significant roles in pathological inflammation, neural differentiation, and oncogenesis. Specifically, HERVs expression has been implicated in several oncogenic processes and the formation of the tumor microenvironment. Indeed, the dual roles of HERVs in cancer, serving as both promoters of oncogenesis and forerunners of the innate antitumor immune response, remain a subject of debate. In this review, we will discuss how HERVs participate in cancer progression and how they are regulated. Our aim is to provide a comprehensive understanding of the fundamental properties and potential function of HERVs in propagating oncogenesis and activating the antitumor immune response. We hope that updated knowledge will reshape our understanding of the critical roles played by HERVs in human evolution and cancer progression.

CD8+ T-cell exhaustion has been identified as a significant contributor to immunosuppression and immune escape in triple-negative breast cancer (TNBC). Dysfunction due to cell exhaustion is characterized by reduced effector capacity and sustained expression of inhibitory receptors (IRs). The factors contributing to CD8+ T-cell exhaustion are multifaceted, encompassing external influences such as the upregulation of IRs, reduction of effector cytokines, and internal changes within the immune cell, including transcriptomic alterations, epigenetic landscape remodeling, and metabolomic shifts. The impact of the altered TNBC tumor microenvironment (TME) on Tex is also a critical consideration. The production of exhausted CD8+ T-cells (CD8+ Tex) is positively correlated with poor prognosis and reduced response rates to immunotherapy in TNBC patients, underscoring the urgent need for the development of novel TNBC immunotherapeutic strategies that target the mechanisms of CD8+ T-cell exhaustion. This review delineates the dynamic trajectory of CD8+ T-cell exhaustion development in TNBC, provides an update on the latest research advancements in understanding its pathogenesis, and offers insights into potential immunotherapeutic strategies.

Bladder cancer (BCa) is the most common malignant tumor of the urinary system. Current treatments often have poor efficacy and carry a high risk of recurrence and progression due to the lack of consideration of tumor heterogeneity. Patient-derived organoids (PDOs) are three-dimensional tissue cultures that preserve tumor heterogeneity and clinical relevance better than cancer cell lines. Moreover, PDOs are more cost-effective and efficient to cultivate compared to patient-derived tumor xenografts, while closely mirroring the tissue and genetic characteristics of their source tissues. The development of PDOs involves critical steps such as sample selection and processing, culture medium optimization, matrix selection, and improvements in culture methods. This review summarizes the methodologies for generating PDOs from patients with BCa and discusses the current advancements in drug sensitivity testing, immunotherapy, living biobanks, drug screening, and mechanistic studies, highlighting their role in advancing personalized medicine.
