Med Res Rev 2023; 43:1946-1973. [PMID: 37102365 DOI: 10.1002/med.21967] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Revised: 03/23/2023] [Accepted: 04/13/2023] [Indexed: 04/28/2023]
Abstract
Surgery remains to be the mainstay of treatment for hepatocellular carcinoma (HCC). Nonetheless, its therapeutic efficacy is significantly impaired by postoperative recurrence, which occurs in more than half of cases as a result of intrahepatic metastasis or de novo tumorigenesis. For decades, most therapeutic strategies on inhibiting postoperative HCC recurrence have been focused on the residual tumor cells but satisfying therapeutic outcomes are barely observed in the clinic. In recent years, a better understanding of tumor biology allows us to shift our focus from tumor cells toward the postoperative tumor microenvironment (TME), which is gradually identified to play a pivotal role in tumor recurrence. In this review, we describe various surgical stress and surgical perturbation on postoperative TME. Besides, we discuss how such alternations in TME give rise to postoperative recurrence of HCC. Based on its clinical significance, we additionally highlight the potential of the postoperative TME as a target for postoperative adjuvant therapeutics.

Abstract
Radical gastrectomy is a mainstay therapy for patients with locally resectable gastric cancer (GC). GC patients who are candidates for radical gastrectomy will experience at least part of the following perioperative events: surgery, anesthesia, pain, intraoperative blood loss, allogeneic blood transfusion, postoperative complications, and their related anxiety, depression and stress response. Considerable clinical studies have shown that these perioperative events can promote recurrence and decrease the long-term survival of GC patients. The mechanisms include activation of neural signaling and the inflammatory response, suppression of antimetastatic immunity, increased release of cancer cells into circulation, and delayed adjuvant therapy, which are involved in every step of the invasion-metastasis cascade. Having appreciated these perioperative events and their influence on the risk of GC recurrence, we can now use this knowledge to find strategies that might substantially prevent the deleterious recurrence-promoting effects of perioperative events, potentially increasing cancer-free survival in GC patients.

Abstract
Lymphatic vessels play an important role in health and in disease. In this study, we evaluated the effects of GSK3-β inhibition on lung lymphatic endothelial cells in vitro. Pharmacological inhibition and silencing of GSK3-β resulted in increased lymphangiogenesis of lung lymphatic endothelial cells. To investigate mechanisms of GSK3-β-mediated lymphangiogenesis, we interrogated the mammalian/mechanistic target of rapamycin pathway and found that inhibition of GSK3-β resulted in PTEN activation and subsequent decreased activation of AKT, leading to decreased p-P70S6kinase levels, indicating inhibition of the mTOR pathway. In addition, consistent with a negative role of GSK3-β in β-catenin stability through protein phosphorylation, we found that GSK3-β inhibition resulted in an increase in β-catenin levels. Simultaneous silencing of β-catenin and inhibition of GSK3-β demonstrated that β-catenin is required for GSK3-β-induced lymphangiogenesis.

Abstract
In this study, we modeled lymphangiogenesis and vascular angiogenesis in a microdevice using a tissue engineering approach. Lymphatic vessels (LV) and blood vessels (BV) were fabricated by sacrificial molding with seeding human lymphatic endothelial cells and human umbilical vein endothelial cells into molded microchannels (600 μm diameter). During subsequent perfusion culture, lymphangiogenesis and vascular angiogenesis were induced by addition of phorbol 12-myristate 13-acetate (PMA) and VEGF-C or VEGF-A characterized by podoplanin and Prox-1 expression. The lymphatic capillaries formed button-like junctions treated with dexamethasone. To test the potential for screening anti-angiogenic (vascular and lymphatic) factors, antagonists of VEGF were introduced. We found that an inhibitor of VEGF-R3 did not completely suppress lymphatic angiogenesis with BVs present, although lymphatic angiogenesis was selectively prevented by addition of a VEGF-R3 inhibitor without BVs. To probe the mechanism of action, we focus on matrix metalloproteinase (MMP) secretion by vascular endothelial cells and lymphatic endothelial cells under monoculture or co-culture conditions. We found that vascular angiogenesis facilitated lymphangiogenesis via remodeling of the local microenvironment by the increased secretion of MMP, mainly by endothelial cells. Applications of this model include a drug screening assay for corneal disease and models for tumorigenesis including lymphatic angiogenesis and vascular angiogenesis.

Abstract
Lymphangiogenesis is the process of new vessel formation from pre-existing lymphatic vessels. The process mainly involves cell adhesion, migration, and tubule formation of lymphatic endothelial cells. Tumor-induced lymphangiogenesis is an important factor contributing to promotion of tumor growth and cancer metastasis via the lymphatic system. Finding the non-toxic agents that can prevent or inhibit lymphangiogenesis may lead to blocking of lymphatic metastasis. Recently, aspirin, a non-steroidal anti-inflammatory drug (NSAID), has been reported to inhibit in vivo lymphangiogenesis in tumor and incision wound models, but the mechanisms of actions of aspirin on anti-lymphangiogenesis have been less explored. In this study, we aim to explore the mechanism underlying the anti-lymphangiogenic effects of aspirin in primary human dermal lymphatic microvascular endothelial (HMVEC-dLy) cells in vitro. Pretreatment of aspirin at non-toxic dose 0.3 mM significantly suppressed in vitro cord formation, adhesion, and the migration abilities of the HMVEC-dLy cells. Western blotting analysis indicated that aspirin decreased expression of vascular cell adhesion molecule-1 (VCAM-1), at both protein and mRNA levels, and these correlated with the reduction of NF-κB p65 phosphorylation. By using NF-κB inhibitor (BAY-11-7085) and VCAM-1 siRNA, we showed that VCAM-1 expression is downstream of NF-κB activation, and this NF-κB/VCAM-1 signaling pathway controls cord formation, adhesion, and the migration abilities of the HMVEC-dLy cells. In summary, we demonstrate the potential of aspirin as an anti-lymphangiogenic agent, and elucidate its mechanism of action.

Abstract
Surgery is a mainstay treatment for patients with solid tumours. However, despite surgical resection with a curative intent and numerous advances in the effectiveness of (neo)adjuvant therapies, metastatic disease remains common and carries a high risk of mortality. The biological perturbations that accompany the surgical stress response and the pharmacological effects of anaesthetic drugs, paradoxically, might also promote disease recurrence or the progression of metastatic disease. When cancer cells persist after surgery, either locally or at undiagnosed distant sites, neuroendocrine, immune, and metabolic pathways activated in response to surgery and/or anaesthesia might promote their survival and proliferation. A consequence of this effect is that minimal residual disease might then escape equilibrium and progress to metastatic disease. Herein, we discuss the most promising proposals for the refinement of perioperative care that might address these challenges. We outline the rationale and early evidence for the adaptation of anaesthetic techniques and the strategic use of anti-adrenergic, anti-inflammatory, and/or antithrombotic therapies. Many of these strategies are currently under evaluation in large-cohort trials and hold promise as affordable, readily available interventions that will improve the postoperative recurrence-free survival of patients with cancer.

Abstract
BACKGROUND Axillary nodes dissection (AND) is an important risk factor for the appearance of breast cancer-related lymphedema (BCRL). The anatomy and pathophysiology leading to the development of BCRL after AND are not completely understood. Despite the existence of lymphedema models after AND, none of them were able to create lymphedemas without additional chemical inflammatory drugs or auxiliary physical techniques (radiotherapy). In this study, we aimed to describe the anatomical changes of AND on a rat's front leg before and after a new surgery technique. METHODS AND RESULTS AND was performed on seven Wistar rats with a new, posterior surgical approach. Indocyanine green mapping was done before and after surgery to detect "normal and secondary superficial lymphatic pathways" of the operated rat's front legs. Twelve months after surgery, dissections were performed. Subcutaneous blue dye injection of the hand was used to observe superficial and deep lymphatic pathways. Postsurgery, an acute edema of arm and shoulder appeared and persisted for 14-21 days. However, none of the rats showed a chronic secondary lymphedema. In two cases, seromas also appeared. All rats showed substitution functional lymphatic pathways as perforating lymph vessels around the surgical sites. CONCLUSION This is the first description of perforating lymph vessels as lymphatic substitution pathways after AND on rats. These results help to understand why a chronic secondary lymphedema could not be created in rats after AND without additional chemical or physical interventions.

Abstract
The main function of the lymphatic system is to control and maintain fluid homeostasis, lipid transport, and immune cell trafficking. In recent years, the pathological roles of lymphangiogenesis, the generation of new lymphatic vessels from preexisting ones, in inflammatory diseases and cancer progression are beginning to be elucidated. Sphingosine-1-phosphate (S1P), a bioactive lipid, mediates multiple cellular events, such as cell proliferation, differentiation, and trafficking, and is now known as an important mediator of inflammation and cancer. In this review, we will discuss recent findings showing the emerging role of S1P in lymphangiogenesis, in inflammation, and in cancer.

Abstract
Noninvasive, longitudinal near-infrared fluorescence (NIRF) imaging was used to detect and quantify lymphangiogenesis following a full-dermis thickness incision in the presence and absence of locally administered vascular endothelial growth factor-C (VEGF-C), a well-known regulator of lymphangiogenesis. Peripheral cytokines/chemokines were also measured in treated and sham-injected animals. Lymphangiogenesis was detected via NIRF imaging by day 7-8 and confirmed by intravital microscopy, while angiogenesis was observed by day 2-3 postincision (PI). All lymph vessel parameters quantified were significantly greater on wounded vs. nonwounded sides of mice. Lymph vessel parameters appeared larger on wounded sides of VEGF-C- relative to NaCl-treated mice, although differences were not significant. Interleukin-1α and interleukin-22 were significantly elevated at day 7 PI relative to respective preincision levels in VEGF-C-treated mice, and decreased by day 21 PI to levels nearing those measured preincision. For the majority of cytokines/chemokines measured, mean responses were significantly greater in VEGF-C- vs. NaCl-treated animals. Local VEGF-C administration may stimulate lymphangiogenesis during tissue repair and regeneration via mediating systemic cytokine/chemokine levels. NIRF imaging can be utilized to detect lymphangiogenesis during wound healing, and offers a promising platform to complement current methods for monitoring wound status and studying the effects of growth factors on healing.

Abstract
Lymphatic vessel growth or lymphangiogenesis occurs during embryonic development and wound healing and plays an important role in tumor metastasis and inflammatory diseases. However, the possibility of noninvasive detection and quantification of lymphangiogenesis has been lacking. Here, we present the Vegfr3(EGFPLuc) mouse model, where an EGFP-luciferase fusion protein, expressed under the endogenous transcriptional control of the Vegfr3 gene, allows the monitoring of physiological and pathological lymphangiogenesis in vivo. We show tracking of lymphatic vessel development during embryogenesis as well as lymphangiogenesis induced by specific growth factors, during wound healing and in contact hypersensitivity (CHS)--induced inflammation where we also monitor down-regulation of lymphangiogenesis by the glucocorticoid dexamethasone. Importantly, the Vegfr3-reporter allowed us to tracking tumor-induced lymphangiogenesis at the tumor periphery and in lymph nodes in association with the metastatic process. This is the first reporter mouse model for luminescence imaging of lymphangiogenesis. It should provide an important tool for studying the involvement of lymphangiogenesis in pathological processes.

Abstract
The lymphatic system has long been accepted as a passive escape route for metastasizing tumor cells. The classic view that lymphatics solely regulate fluid balance, lipid metabolism, and immune cell trafficking to the LN is now being challenged. Research in the field is entering a new phase with increasing evidence suggesting that lymphatics play an active role modulating inflammation, autoimmune disease, and the anti-tumor immune response. Evidence exists to suggest that the lymphatics and chemokines guide LN bi-functionally, driving immunity vs. tolerance according to demand. At sites of chronic inflammation, autoimmunity, and tumors, however, the same chemokines and aberrant lymphangiogenesis foster disease progression. These caveats point to the existence of a complex, finely balanced relationship between lymphatics and the immune system in health and disease. This review discusses emerging concepts in the fields of immunology, tumor biology, and lymphatic physiology, identifying critical, overlapping functions of lymphatics, the LN and lymphoid factors in tipping the balance of immunity vs. tolerance in favor of a growing tumor.

Abstract
Recent studies have implicated that lymphangiogenesis plays a role in the development of metastasis in experimental cancer models and in certain types of human tumors. Epidemiological and laboratory data suggest that non steroidal anti-inflammatory agents (NSAIDs) have antitumor activities, although the mechanisms have not been elucidated. This systematic review aimed to synthesize data on the effect of aspirin and other NSAIDs on lymphangiogenesis. In particular, an answer was attempted to be found for the following primary questions: Is there an effect of aspirin and NSAIDs on lymphangiogenesis? If yes, is this effect mediated through COX-II inhibition or through COX-II-independent mechanisms? Electronical databases were searched with the appropriate search terms for the period from 1966 up to and including February 2011. The few identified experimental trials indicated that aspirin and other NSAIDs inhibit lymphangiogenesis, with a potential decrease in metastatic spread, possibly through COX-II-dependent regulation of VEGF-C expression. COX-II-independent mechanisms of inhibition of lymphangiogenesis by salicylates and the other NSAIDs have not been investigated. Although further research validation is needed, this proposed effect of NSAIDs might have therapeutic implications in chemoprevention, adjuvant chemotherapy, and treatment of metastatic disease.

Abstract
Despite significant advances in the understanding of tissue responses to biomaterials, most implants are still plagued by inflammatory responses which can lead to fibrotic encapsulation. This is of dire consequence in tissue engineering, where seeded cells and bioactive components are separated from the native tissue, limiting the regenerative potential of the design. Additionally, these interactions prevent desired tissue integration and angiogenesis, preventing functionality of the design. Recent evidence supports that mesenchymal stem cells (MSC) and hematopoietic stem cells (HSC) can have beneficial effects which alter the inflammatory responses and improve healing. The purpose of this study was to examine whether stem cells could be targeted to the site of biomaterial implantation and whether increasing local stem cell responses could improve the tissue response to PLGA scaffold implants. Through incorporation of SDF-1alpha through factor adsorption and mini-osmotic pump delivery, the host-derived stem cell response can be improved resulting in 3X increase in stem cell populations at the interface for up to 2 weeks. These interactions were found to significantly alter the acute mast cell responses, reducing the number of mast cells and degranulated mast cells near the scaffold implants. This led to subsequent downstream reduction in the inflammatory cell responses, and through altered mast cell activation and stem cell participation, increased angiogenesis and decreased fibrotic responses to the scaffold implants. These results support that enhanced recruitment of autologous stem cells can improve the tissue responses to biomaterial implants through modifying/bypassing inflammatory cell responses and jumpstarting stem cell participation in healing at the implant interface.

Abstract
OBJECTIVES Presence of lymphatics in adventitia of major arteries remains controversial. Presence of lymphatics in adventitia of internal carotid artery was not documented and its relation to atherosclerosis was not studied. The aim of our study was to evaluate presence of lymphatic vessels in adventitia of internal carotid artery in healthy and atherosclerotic arteries. METHODS Fragments of arterial wall of internal carotid artery were obtained during the surgical eversion endarterectomy in 15 patients with internal carotid artery stenosis and 2 healthy organ donors. 21 arteries were studied. Patients age ranged from 56 to 77 years. Fragments of arterial wall were embeded in paraffin. Lymphatics of arterial adventitia were visualized with immunohistochemistry using LYVE-1 and anty-podoplanin antibodies. RESULTS The lymphatic vessels were visualized in adventitia of 20 carotid arteries. The serial sections have revealed that both LYVE-1 and podoplanin have identical specificity for lymphatic endothelium Number of lymphatics in adventitia significantly correlated with thickness of intima (p<0.046). CONCLUSIONS Lymphatics are present in adventitia of internal carotid artery. Number of adventitial lymphatics increases with severity of atherosclerosis measured as intimal thickness.
