Carcinoma epizoótico en el invierno Flounder, Pseudopleuronectes americanus
Resumen
Las neoplasias se encontraron en la borla de invierno (Pseudopleuronectes americanus) del puerto de Boston. Estos tumores hepáticos, incluidos los colangiocarcinomas y los hepatocarcinomas, se parecen a los observados en roedores expuestos a carcinógenos.
Área de la Ciencia:
- Biología marina Biología marina.
- Ictiología Ictiología.
- Toxicología ambiental y toxicología ambiental.
Sus antecedentes:
- La flor de invierno (Pseudopleuronectes americanus) es una especie de pez comercialmente importante en el noreste de los Estados Unidos.
- Estudios anteriores han planteado preocupaciones sobre la salud de la vida marina en el puerto de Boston.
Objetivo del estudio:
- Para investigar la prevalencia de las neoplasias hepáticas en la borla de invierno del puerto de Boston.
- Para caracterizar los tipos de lesiones hepáticas observadas y compararlas con lesiones conocidas inducidas por carcinógenos.
Principales métodos:
- Examen histopatológico de tejidos hepáticos de plato de invierno.
- Análisis de 200 muestras de peces recolectadas en el puerto de Boston.
Principales resultados:
- Se detectó una alta prevalencia de neoplasias en la borla de invierno examinada.
- Las lesiones identificadas como colangiocarcinomas y hepatocarcinomas estaban presentes en 16 de los 200 peces.
- Las lesiones observadas eran morfológicamente similares a las inducidas por carcinógenos en modelos de roedores.
Conclusiones:
- La borla de invierno en el puerto de Boston exhibe una incidencia significativa de tumores de hígado.
- Los hallazgos sugieren una posible exposición a agentes cancerígenos en el entorno del puerto de Boston.
- Se requiere más investigación para identificar los carcinógenos específicos y sus fuentes que afectan a las poblaciones de flotilla de invierno.

Mouse Models of Cancer Study
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
Rabies
Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
