GPR97-Gα12-mTORC1 signaling drives myotube hypertrophy: identification of 5-hydroxy-7-methoxyflavone as a pathway activator.

Fujita Shuhei S, Kimura Ayano A, Maekawa Daisuke D, Kubota Mai M et al.

Elucidating novel signaling pathways that drive myotube hypertrophy may provide new insights into the mechanisms regulating skeletal muscle growth. We previously reported that 5-hydroxy-7-methoxyflavone (HMF) induces hypertrophy of murine C2C12 myotubes; however, the underlying molecular mechanism remains unclear. Here, loss- and gain-of-function analyses revealed that GPR97 positively regulates myotube size. Furthermore, knockdown and rescue experiments demonstrated that GPR97 is required for HMF-induced myotube hypertrophy. HMF activated mTORC1 signaling in myotubes, and intramuscular administration of HMF also activated mTORC1 signaling in mouse skeletal muscle in vivo. Gpr97 knockdown abolished HMF-induced mTORC1 signaling and protein synthesis. Furthermore, depletion of Gna12 and expression of dominant-negative Gα12 abolished HMF-induced myotube hypertrophy. Gna12 depletion also suppressed HMF-induced mTORC1 signaling and protein synthesis. Beclomethasone dipropionate, a reported GPR97 ligand, suppressed HMF-induced hypertrophy and mTORC1 signaling, while further enhancing HMF-induced serum response factor (SRF)-dependent transcription. Although dominant-negative RhoA inhibited HMF-induced SRF-dependent transcriptional activity, it did not affect myotube hypertrophy. These findings indicate that GPR97-Gα12-mTORC1 signaling promotes hypertrophy independent of the Gα12-RhoA-SRF pathway. GPR97 was predominantly expressed on the myotube surface as a C-terminal fragment generated by N-terminal fragment (NTF) cleavage, and HMF reduced its surface expression. HMF induced hypertrophy in myotubes expressing an NTF cleavage-resistant GPR97 mutant, but not in those expressing an NTF-deleted mutant. These results indicate that NTF cleavage is dispensable and suggest that NTF contributes to GPR97-mediated hypertrophic signaling. These findings identify a novel GPR97-Gα12-mTORC1 signaling axis that mediates HMF-induced myotube hypertrophy.

Particle engineering, aerosol physics, and pulmonary deposition of single-inhaler triple ICS/LABA/LAMA therapies in obstructive airway diseases.

Sorino Claudio C, Virchow Johann Christian JC, Spanevello Antonio A, Buscemi Agata A et al.

Single-inhaler triple therapy (SITT) combining an inhaled corticosteroid, long-acting β2-agonist, and long-acting muscarinic antagonist (ICS/LABA/LAMA) represents the current ceiling of inhaled pharmacotherapy for moderate-to-very-severe chronic obstructive pulmonary disease and severe uncontrolled asthma. Five device platforms are currently approved: two extrafine formulations delivering beclomethasone dipropionate/formoterol/glycopyrronium (the Modulite solution pressurised metered-dose inhaler [pMDI] and the NEXThaler breath-actuated dry powder inhaler [DPI]); the co-suspension pMDI Aerosphere platform (budesonide/glycopyrrolate/formoterol); the standard-particle Ellipta DPI (fluticasone furoate/umeclidinium/vilanterol); and the low-resistance, single-dose capsule-based DPI Breezhaler (mometasone furoate/indacaterol/glycopyrronium). Despite a shared pharmacological class, these systems differ in aerosol physics, particle engineering, intrapulmonary deposition patterns, and device-patient interaction. Furthermore, some of them are authorized only for COPD or asthma. This narrative review examines the technology and in vivo deposition evidence for each SITT platform, discusses real-world performance determinants (particle size, flow dependency, technique robustness), and proposes an expert-informed framework for patient-level device selection. Methodological limitations include reliance on in silico Functional Respiratory Imaging data when in vivo scintigraphy is unavailable, and inconsistent dose denominators across studies (emitted vs. metered dose). Cross-platform comparisons are limited by heterogeneous methodologies, and no SITT platform has demonstrated universal superiority. In platform-specific studies, NEXThaler shows relatively high lung deposition (∼55% of emitted dose) though flow-dependent; Aerosphere is robust to inhalation technique variations; Modulite provides extrafine, peripheral delivery; Ellipta and Breezhaler offer once-daily convenience with moderate deposition. Rational device selection requires structured assessment of patient inspiratory capacity, disease phenotype, coordination, and adherence. Head-to-head scintigraphy and prospective imaging-outcome studies represent major evidence gaps.

Betamethasone Dipropionate Inhibits NLRP3 Inflammasome Activation by Suppressing Pro-IL-1β Expression.

Huang Weichen W, Xie Shoufeng S, Rong Xinyu X, Liu Yongzhi Y et al.

The NOD-like receptor Family, pyrin domain-containing 3 protein (NLRP3) inflammasome is a macromolecular complex critical for inflammatory responses. Its excessive activation or improper regulation is intimately associated with the development of various inflammatory diseases. However, currently available drugs directly targeting the NLRP3 inflammasome are limited. In preliminary analyses, detecting the level of secreted interleukin-1 beta (IL-1β) revealed that betamethasone-17,21-dipropionate (also known as betamethasone dipropionate, BD), a clinically used glucocorticoid, potentially inhibits NLRP3 inflammasome activation. In vitro, the role and preliminary mechanism of BD in inhibiting the activation of NLRP3 inflammasome were investigated in THP-1-differentiated macrophages and bone marrow-derived macrophages (BMDMs) using enzyme-linked immunosorbent assay (ELISA), Cell Counting Kit-8 (CCK-8), reverse transcription-quantitative polymerase chain reaction (RT-qPCR), and western blotting (WB). The preliminary effects of BD on the assembly of NLRP3 inflammasome were assessed in HEK293T cells overexpressing NLRP3/ASC/caspase-1/NEK7 through drug affinity responsive target stability (DARTS) and co-immunoprecipitation (Co-IP) approaches. In vivo, the effect of BD on LPS-induced systemic inflammation was assessed by measuring serum concentrations of IL-1β and TNF-α via ELISA, and by recording mouse survival rates and body weights. BD significantly inhibited NLRP3 inflammasome activation by suppressing pro-IL-1β expression in vitro. Mechanistic studies showed that it decreased pro-IL-1β expression by suppressing NF-κB signaling. In vivo, BD downregulated the serum concentrations of IL-1β and TNF-α, and increase the survival rate of mice using the LPS-induced systemic inflammation model. Collectively, our data verify that BD inhibits NLRP3 inflammasome activation by suppressing pro-IL-1β expression. These findings suggest that BD may be a potential therapeutic approach for inflammatory diseases. However, further studies are needed to elucidate its precise role and specific mechanism in clinical practice.

Recent advancements in phytotherapeutics for controlling babesiosis and theileriosis.

Prajapati Amar A, Rajput Ritika R, Srivastava Anand A

Babesiosis/theileriosis is a tick-borne disease caused by protozoan parasites of the genus Babesia and Theileria. Tick species of genera, such as Ixodes, Rhipicephalus, Haemaphysalis and Hyalomma, transmit these parasites. These diseases threaten livestock productivity and health, particularly in tropical and subtropical areas. These diseases have a significant economic impact due to reduced milk and meat production, reproductive losses, higher veterinary expenses, and, in extreme cases, animal mortality. Even after decades of research, piroplasmosis is still difficult to control and manage. The most common drugs to treat this disease include buparvaquone, diminazene aceturate, and imidocarb dipropionate. These drugs are known for toxicity, and recent reports of the emergence of resistance to these drugs are worrisome. Hence, the development of alternative sustainable control methods is necessary. This review examines the current status of research on plant-based natural extracts/compounds, with particular emphasis on combination therapies integrating natural products with synthetic antiparasitic agents.

Therapeutic outcomes of CAL/BDP PAD-based cream in patients with mild-to-moderate psoriasis: insights from four case reports.

Dattola Annunziata A, Sechi Andrea A, Gargiulo Luigi L, Loconsole Francesco F

Topical medications are commonly used to manage mild-to-moderate psoriasis as adjunctive treatments in patients receiving phototherapy, systemic agents or biologic therapies. Amongst available topical options, the fixed-dose combination of calcipotriol (CAL) and betamethasone dipropionate (BDP) has demonstrated efficacy and tolerability in clinical trials, with most adverse events being mild and transient local reactions. CAL/BDP has recently been formulated as a cream using polyaphron dispersion (PAD) technology to improve its rheological behaviour and sensory characteristics. We describe the use of CAL/BDP PAD-based cream specifically in patients with mild-to-moderate psoriasis across four Italian centres. The first case involves a man with mild-to-moderate scalp psoriasis, in whom CAL/BDP PAD-based cream was effective in this high-impact disease location. The second case focuses on a patient with pretibial psoriasis, a difficult-to-treat site. The third case is of a woman with palmoplantar psoriasis who reported clinical improvement in the lesions and increased treatment compliance compared with her previous therapies. The last case describes the concomitant use of CAL/BDP PAD-based cream with a biologic drug, resulting in optimized lesion clearance. CAL/BDP PAD-based cream appears promising for managing psoriasis in specific contexts such as lesions in difficult-to-treat areas or residual disease during biologic therapy. Further real-world data and clinical observations will be important to clarify how this formulation can be integrated into individualized management strategies for mild-to-moderate psoriasis.

Economic Burden and Cost Differences Between Branded and Generic Topical Antifungals in India.

Dt Prateek P, Dongerkery Kavitha K, Deolekar Pradnya P, Dahibhate Atharva A et al.

India's pharmaceutical market is characterized by a significant presence of both generic and branded drugs, particularly for common ailments such as superficial mycoses (SFMs), which pose a substantial public health and economic burden. Patients in tropical countries like India, which have common superficial mycoses, need prolonged treatment because of their recurrence rates after initial treatment and due to incomplete therapy. Given the high variability in drug pricing and the imperative for cost-effective healthcare, a pharmacoeconomic analysis comparing generic and branded topical antifungals in India is crucial to inform prescribing practices and optimize resource allocation. The price comparison of various topical antifungal medications from different brands was conducted by using the latest information from the "Monthly Index of Medical Specialties" August to October 2025, and 1mg online pharmacy and Jan Aushadhi website. The study calculated the total expenses for 30 mL and 30 g dosage forms, which included cream, ointment, lotion, eye drops, and shampoo products of each drug brand. We conducted a comparison between different drug brands through their cost ratio, and percentage cost variation (PCV) analysis was done, keeping generic medicines prices (retrieved from the Jan Aushadhi website) as baseline values. The data analysis showed a significant variation in the costs of different brands of topical antifungals in the Indian market. After analysis, we identified itraconazole 1% ointment to have the highest cost variation at 8335.1%, followed by clotrimazole dusting powder (4740%). Ketoconazole 2% cream, bifonazole 1% lotion, and sertaconazole shampoo showed the smallest variation at 3.29%, 3.5%, and 11.3%, respectively. When generic and branded topical antifungals were compared, the highest cost variation was seen for clotrimazole 1% cream (3431.7%), and the least variation was observed for ketoconazole 2% powder (135.4%). When combination topical antifungals were compared, the highest percentage cost variation of 1479.4% was seen for clotrimazole 1%w/w and beclomethasone dipropionate 0.025%w/w cream, and the least percentage cost variation of 38.8% was seen for terbinafine (1% w/w) + ciprofloxacin (1% w/w) + metronidazole (1% w/w) + clobetasol (0.05% w/w). The market for topical antifungal agents demonstrates substantial price variation among available products. Regulatory authorities, pharmaceutical manufacturers, and clinicians must collaborate to achieve optimal reductions in drug costs. Strict implementation of cost regulation policies, along with increased awareness among clinicians regarding the rational selection of cost-effective therapies, is essential.
